1.2 Description
The processor core is an ARM926EJ-S RISC processor. The ARM926EJ-S is a 32-bit processor core that
performs 32-bit and 16-bit instructions and processes 32-bit, 16-bit, and 8-bit data. The core uses
pipelining so that all parts of the processor and memory system can operate continuously. The ARM core
incorporates:
• A coprocessor 15 (CP15) and protection module
• Data and program Memory Management Units (MMUs) with table look-aside buffers.
• Separate 16K-byte instruction and 8K-byte data caches. Both are four-way associative with virtual
index virtual tag (VIVT).
DM355 performance is enhanced by its MPEG/JPEG co-processor. The MPEG/JPEG co-processor
performs the computational operations required for image processing; JPEG compression and MPEG1,2,4
video and imaging standards.
The device has a Video Processing Subsystem (VPSS) with two configurable video/imaging peripherals:
• A Video Processing Front-End (VPFE)
• A Video Processing Back-End (VPBE)
The VPFE port provides an interface for CCD/CMOS imager modules and video decoders. The VPBE
provides hardware On Screen Display (OSD) support and composite NTSC/PAL and digital LCD output.
The DM355 peripheral set includes:
• An inter-integrated circuit (I2C) Bus interface
• Two audio serial ports (ASP)
• Three 64-bit general-purpose timers each configurable as two independent 32-bit timers
• A 64-bit watchdog timer
• Up to 104-pins of general-purpose input/output (GPIO) with programmable interrupt/event generation
modes, multiplexed with other peripherals
• Three UARTs with hardware handshaking support on one UART
• Three serial port Interfaces (SPI)
• Four pulse width modulator (PWM) peripherals
• Four real time out (RTO) outputs
• Two Multi-Media Card / Secure Digital (MMC/SD) interfaces
• A USB 2.0 full and high-speed device and host interface
• Two external memory interfaces:
– An asynchronous external memory interface (AEMIF) for slower memories/peripherals such as
NAND and OneNAND,
– A high speed synchronous memory interface for DDR2/mDDR.
For software development support the has a complete set of ARM development tools which include: C
compilers, assembly optimizers to simplify programming and scheduling, and a Windows™ debugger
interface for visibility into source code execution.

2.3 Pin Assignments
Extensive use of pin multiplexing is used to accommodate the largest number of peripheral functions in
the smallest possible package. Pin multiplexing is controlled using a combination of hardware
configuration at device reset and software programmable register settings.
Pin Map (Bottom View)
Figure 2-1 through Figure 2-4 show the pin assignments in four quadrants (A, B, C, and D). Note that
micro-vias are not required. Contact your TI representative for routing recommendations.

2.4 Pin Functions
The pin functions tables (Table 2-4 through Table 2-22) identify the external signal names, the associated
pin (ball) numbers along with the mechanical package designator, the pin type, whether the pin has any
internal pullup or pulldown resistors, and a functional pin description. For more detailed information on
device configuration, peripheral selection, multiplexed/shared pins, and debugging considerations, see
Section 3. For the list of all pin in chronological order see Section 2.5
2.4.1
Image Data Input - Video Processing Front End
The definition of the CCD controller data input signals depend on the input mode selected.
• In 16-bit YCbCr mode, the Cb and Cr signals are multiplexed on the Cl signals and the order is
configurable (i.e., Cb first or Cr first).
• In 8-bit YCbCr mode, the Y, Cb, and Cr signals are multiplexed and not only is the order selectable,
but also the half of the bus used.

Image Data Output - Video Processing Back End (VPBE)
The Video Encoder/Digital LCD interface module in the video processing back end has an external signal
interface for digital image data output as described in Table 2-7 and Table 2-8.
The digital image data output signals support multiple functions / interfaces, depending on the display
mode selected. The following table describes these modes. Parallel RGB mode with more than RGB565
signals requires enabling pin multiplexing to support (i.e., for RGB666 mode).

I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground, A = Analog signal.
Specifies the operating I/O supply voltage for each signal. See Section 5.3, Power Supplies for more detail.
PD = pull-down, PU = pull-up. (To pull up a signal to the opposite supply rail, a 1 kΩ resistor should be used.)
To reduce EMI and reflections, depending on the trace length, approximately 22 Ω to 50 Ω damping resistors are recommend on the
following outputs placed near the DM355: YOUT(0-7),COUT(0-7), HSYNC,VSYNC,LCD_OE,FIELD,EXTCLK,VCLK. The trace lengths
should be minimized.

I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground, A = Analog signal.
Specifies the operating I/O supply voltage for each signal. See Section 5.3, Power Supplies for more detail.
PD = pull-down, PU = pull-up. (To pull up a signal to the opposite supply rail, a 1 kΩ resistor should be used.)
To reduce EMI and reflections, depending on the trace length, approximately 22 Ω to 50 Ω damping resistors are recommend on the
following outputs placed near the DM355: YOUT(0-7),COUT(0-7), HSYNC,VSYNC,LCD_OE,FIELD,EXTCLK,VCLK. The trace lengths
should be minimized.

2.6 Device Support
2.6.1
Development Tools
TI offers an extensive line of development tools for DM355 systems, including tools to evaluate the
performance of the processors, generate code, develop algorithm implementations, and fully integrate and
debug software and hardware modules. The tools support documentation is electronically available within
the Code Composer Studio™ Integrated Development Environment (IDE).
The following products support development of DM355 based applications:
Software Development Tools:
Code Composer Studio™ Integrated Development Environment (IDE): including Editor
C/C++/Assembly Code Generation, and Debug plus additional development tools
Hardware Development Tools:
Extended Development System (XDS™) Emulator (supports TMS320DM355 DMSoC multiprocessor
system debug) EVM (Evaluation Module)
For a complete listing of development-support tools for the TMS320DM355 DMSoC platform, visit the
Texas Instruments web site on the Worldwide Web at http://www.ti.com. For information on pricing and
availability, contact the nearest TI field sales office or authorized distributor.
2.6.2
Device Nomenclature
To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all
DSP devices and support tools. Each DSP commercial family member has one of three prefixes: TMX,
TMP, or TMS (e.g., ). Texas Instruments recommends two of three possible prefix designators for its
support tools: TMDX and TMDS. These prefixes represent evolutionary stages of product development
from engineering prototypes (TMX/TMDX) through fully qualified production devices/tools (TMS/TMDS).
Device development evolutionary flow:
TMX
Experimental device that is not necessarily representative of the final device's electrical
specifications.
TMP
Final silicon die that conforms to the device's electrical specifications but has not completed
quality and reliability verification.
TMS
Fully-qualified production device.
Support tool development evolutionary flow:
TMDX
Development-support product that has not yet completed Texas Instruments internal
qualification testing.
TMDS
Fully qualified development-support product.

SPRS463 – SEPTEMBER 2007
TMX and TMP devices and TMDX development-support tools are shipped against the following
disclaimer:
"Developmental product is intended for internal evaluation purposes."
TMS devices and TMDS development-support tools have been characterized fully, and the quality and
reliability of the device have been demonstrated fully. TI's standard warranty applies.
Predictions show that prototype devices (TMX or TMP) have a greater failure rate than the standard
production devices. Texas Instruments recommends that these devices not be used in any production
system because their expected end-use failure rate is undefined. Only qualified production devices are to
be used in production.
PRODUCT PREVIEW
TI device nomenclature also includes a suffix with the device family name. This suffix indicates the
package type (for example, ZCE), the temperature range (for example, "Blank" is the commercial
temperature range), and the device speed range in megahertz (for example, 202 is 202.5 MHz). The
following figure provides a legend for reading the complete device name for any TMS320DM355 DMSoC
platform member.

describes the serial peripheral interface (SPI) in the TMS320DM35x Digital Media
System-on-Chip (DMSoC). The SPI is a high-speed synchronous serial input/output port that
allows a serial bit stream of programmed length (1 to 16 bits) to be shifted into and out of the
device at a programmed bit-transfer rate. The SPI is normally used for communication
between the DMSoC and external peripherals. Typical applications include an interface to
external I/O or peripheral expansion via devices such as shift registers, display drivers, SPI
EPROMs and analog-to-digital converters.

3.2 ARM926EJ-S RISC CPU
The ARM Subsystem integrates the ARM926EJ-S processor. The ARM926EJ-S processor is a member of
ARM9 family of general-purpose microprocessors. This processor is targeted at multi-tasking applications
where full memory management, high performance, low die size, and low power are all important. The
ARM926EJ-S processor supports the 32-bit ARM and 16 bit THUMB instruction sets, enabling the user to
trade off between high performance and high code density. Specifically, the ARM926EJ-S processor
supports the ARMv5TEJ instruction set, which includes features for efficient execution of Java byte codes,
providing Java performance similar to Just in Time (JIT) Java interpreter, but without associated code
overhead.
The ARM926EJ-S processor supports the ARM debug architecture and includes logic to assist in both
hardware and software debug. The ARM926EJ-S processor has a Harvard architecture and provides a
complete high performance subsystem, including:
• ARM926EJ -S integer core
• CP15 system control coprocessor
• Memory Management Unit (MMU)
• Separate instruction and data Caches
• Write buffer
• Separate instruction and data Tightly-Coupled Memories (TCMs) [internal RAM] interfaces

3.2.1
CP15
The ARM926EJ-S system control coprocessor (CP15) is used to configure and control instruction and
data caches, Tightly-Coupled Memories (TCMs), Memory Management Unit (MMU), and other ARM
subsystem functions. The CP15 registers are programmed using the MRC and MCR ARM instructions,
when the ARM in a privileged mode such as supervisor or system mode.
MMU
The ARM926EJ-S MMU provides virtual memory features required by operating systems such as Linux,
WindowCE, ultron, ThreadX, etc. A single set of two level page tables stored in main memory is used to
control the address translation, permission checks and memory region attributes for both data and
instruction accesses. The MMU uses a single unified Translation Lookaside Buffer (TLB) to cache the
information held in the page tables. The MMU features are:
• Standard ARM architecture v4 and v5 MMU mapping sizes, domains and access protection scheme.
• Mapping sizes are:
– 1MB (sections)
– 64KB (large pages)
– 4KB (small pages)
– 1KB (tiny pages)
• Access permissions for large pages and small pages can be specified separately for each quarter of
the page (subpage permissions)
• Hardware page table walks
• Invalidate entire TLB, using CP15 register 8
• Invalidate TLB entry, selected by MVA, using CP15 register 8
• Lockdown of TLB entries, using CP15 register 10
3.2.3
Caches and Write Buffer
The size of the Instruction Cache is 16KB, Data cache is 8KB. Additionally, the Caches have the following
features:
• Virtual index, virtual tag, and addressed using the Modified Virtual Address (MVA)
• Four-way set associative, with a cache line length of eight words per line (32-bytes per line) and with
two dirty bits in the Dcache
• Dcache supports write-through and write-back (or copy back) cache operation, selected by memory
region using the C and B bits in the MMU translation tables.
• Critical-word first cache refilling
• Cache lockdown registers enable control over which cache ways are used for allocation on a line fill,
providing a mechanism for both lockdown, and controlling cache corruption
• Dcache stores the Physical Address TAG (PA TAG) corresponding to each Dcache entry in the TAG
RAM for use during the cache line write-backs, in addition to the Virtual Address TAG stored in the
TAG RAM. This means that the MMU is not involved in Dcache write-back operations, removing the
possibility of TLB misses related to the write-back address.
• Cache maintenance operations provide efficient invalidation of, the entire Dcache or Icache, regions of
the Dcache or Icache, and regions of virtual memory.

SPRS463 – SEPTEMBER 2007
The write buffer is used for all writes to a noncachable bufferable region, write-through region and write
misses to a write-back region. A separate buffer is incorporated in the Dcache for holding write-back for
cache line evictions or cleaning of dirty cache lines. The main write buffer has 16-word data buffer and a
four-address buffer. The Dcache write-back has eight data word entries and a single address entry.
3.2.4
Tightly Coupled Memory (TCM)
PRODUCT PREVIEW
ARM internal RAM is provided for storing real-time and performance-critical code/data and the Interrupt
Vector table. ARM internal ROM enables non-AEMIF boot options, such as NAND, UART, and HPI. The
RAM and ROM memories interfaced to the ARM926EJ-S via the tightly coupled memory interface that
provides for separate instruction and data bus connections. Since the ARM TCM does not allow
instructions on the D-TCM bus or data on the I-TCM bus, an arbiter is included so that both data and
instructions can be stored in the internal RAM/ROM. The arbiter also allows accesses to the RAM/ROM
from extra-ARM sources (e.g., EDMA or other masters). The ARM926EJ-S has built-in DMA support for
direct accesses to the ARM internal memory from a non-ARM master. Because of the time-critical nature
of the TCM link to the ARM internal memory, all accesses from non-ARM devices are treated as DMA
transfers.
Instruction and Data accesses are differentiated via accessing different memory map regions, with the
instruction region from 0x0000 through 0x7FFF and data from 0x10000 through 0x17FFF. Placing the
instruction region at 0x0000 is necessary to allow the ARM Interrupt Vector table to be placed at 0x0000,
as required by the ARM architecture. The internal 32-KB RAM is split into two physical banks of 16KB
each, which allows simultaneous instruction and data accesses to be accomplished if the code and data
are in separate banks.
3.2.5
Advanced High-performance Bus (AHB)
The ARM Subsystem uses the AHB port of the ARM926EJ-S to connect the ARM to the configuration bus
and the external memories. Arbiters are employed to arbitrate access to the separate D-AHB and I-AHB
by the configuration bus and the external memories bus.
3.2.6
Embedded Trace Macrocell (ETM) and Embedded Trace Buffer (ETB)
To support real-time trace, the ARM926EJ-S processor provides an interface to enable connection of an
Embedded Trace Macrocell (ETM). The ARM926ES-J Subsystem in DM355 also includes the Embedded
Trace Buffer (ETB). The ETM consists of two parts:
• Trace Port provides real-time trace capability for the ARM9.
• Triggering facilities provide trigger resources, which include address and data comparators, counter,
and sequencers.
The DM355 trace port is not pinned out and is instead only connected to the Embedded Trace Buffer. The
ETB has a 4KB buffer memory. ETB enabled debug tools are required to read/interpret the captured trace
data.
3.3
Memory Mapping
The ARM memory map is shown in Table 2-2 and Table 2-3. This section describes the memories and
interfaces within the ARM's memory map.
3.3.1
ARM Internal Memories
The ARM has access to the following ARM internal memories:
• 32KB ARM Internal RAM on TCM interface, logically separated into two 16KB pages to allow
simultaneous access on any given cycle if there are separate accesses for code (I-TCM bus) and data
(D-TCM) to the different memory regions.
• 8KB ARM Internal ROM

3.4 ARM Interrupt Controller (AINTC)
The DM355 ARM Interrupt Controller (AINTC) has the following features:
• Supports up to 64 interrupt channels (16 external channels)
• Interrupt mask for each channel
• Each interrupt channel can be mapped to a Fast Interrupt Request (FIQ) or to an Interrupt Request
(IRQ) type of interrupt.
• Hardware prioritization of simultaneous interrupts
• Configurable interrupt priority (2 levels of FIQ and 6 levels of IRQ)
• Configurable interrupt entry table (FIQ and IRQ priority table entry) to reduce interrupt processing time
The ARM core supports two interrupt types: FIQ and IRQ. See the ARM926EJ-S Technical Reference
Manual for detailed information about the ARM’s FIQ and IRQ interrupts. Each interrupt channel is
mappable to an FIQ or to an IRQ type of interrupt, and each channel can be enabled or disabled. The
INTC supports user-configurable interrupt-priority and interrupt entry addresses. Entry addresses minimize
the time spent jumping to interrupt service routines (ISRs). When an interrupt occurs, the corresponding
highest priority ISR’s address is stored in the INTC’s ENTRY register. The IRQ or FIQ interrupt routine can
read the ENTRY register and jump to the corresponding ISR directly. Thus, the ARM does not require a
software dispatcher to determine the asserted interrupt.
3.4.1
Interrupt Mapping
The AINTC takes up to 64 ARM device interrupts and maps them to either the IRQ or to the FIQ of the
ARM. Each interrupt is also assigned one of 8 priority levels (2 for FIQ, 6 for IRQ). For interrupts with the
same priority level, the priority is determined by the hardware interrupt number (the lowest number has the
highest priority). Table 3-1 shows the connection of device interrupts to the ARM.

are multiplexed and you must use the register ARM_INTMUX in the System Control Module to select the interrupt source for multiplexed
interrupts. Refer to the ARM Subsystem Guide for more information on the System Control Module register ARM_INTMUX.

3.5 Device Clocking
3.5.1
Overview
PRODUCT PREVIEW
The DM355 requires one primary reference clock . The reference clock frequency may be generated
either by crystal input or by external oscillator. The reference clock is the clock at the pins named
MXI1/MXOI. The reference clock drives two separate PLL controllers (PLLC1 and PLLC2). PLLC1
generates the clocks required by the ARM, MPEG and JPEG co-processor, VPBE, VPSS, and
peripherals. PLL2 generates the clock required by the DDR PHY. A block diagram of DM355's clocking
architecture is shown in Figure 5-1. The PLLs are described further in Section 3.6.

Peripheral Clocking Considerations
3.5.4.1 Video Processing Back End Clocking
The Video Processing Back End (VPBE) is a sub-module of the VPSS (Video Processing Subsystem).
The VPBE is designed to interface with a variety of LCDs and an internal DAC module. There are two
asynchronous clock domains in the VPBE: an internal clock domain and an external clock domain. The
internal clock domain is driven by the VPSS clock (PLL1 SYSCLK4). The external clock domain is
configurable; you can select one of five source:
• 24 MHz crystal input at MXI1
• 27 MHz crystal input at MXI2 (optional feature, not typically used)
• PLL1 SYSCLK3
• EXTCLK pin (external VPBE clock input pin)
• PCLK pin (VPFE pixel clock input pin)
See the TMS320DM355 DMSoC Video Processing Back End (VPBE) User's Guide for complete
information on VPBE clocking.
3.5.4.2 USB Clocking
The USB Controller is driven by two clocks: an output clock of PLL1 (SYSCLK2) and an output clock of
the USB PHY.
NOTE
For proper USB function, SYSCLK2 must be greater than 60 MHz.
The USB PHY takes an input clock that is configurable by the USB PHY clock source bits (PHYCLKSRC)
in the USB PHY control register (USB_PHY_CTL) in the System Control Module. When a 24 MHz crystal
is used at MXI1/MXO1, set PHYCLKSRC to 0. This will present a 24 MHz clock to the USB PHY. When a
36 MHz crystal is used at MXI1/MXO1, set PHYCLKSRC to 1. This will present a 12 MHz clock (36 MHz
divided internally by three) to the USB PHY. The USB PHY is capable of accepting only 24 MHz and 12
MHz; thus you must use either a 24 MHz or 36 MHz crystal at MXI1/MXO1. See the TMS320DM355
DMSoC Univeral Serial Bus (USB) Controller User's Guide (SPRUED2) for more information. See the
TMS320DM355 DMSoC ARM Subsystem User's Guide for more information on the System Control
Module.

This section describes the PLL Controllers for PLL1 and PLL2. See the TMS320DM355 Digital Media
System-on-Chip ARM Subsystem User's Guide for more information on the PLL controllers.
3.6.1
PLL Controller Module
The DM355 has two PLL controllers that provide clocks to different components of the chip. PLL controller
1 (PLLC1) provides clocks to most of the components of the chip. PLL controller 2 (PLLC2) provides
clocks to the DDR PHY.
PRODUCT PREVIEW
As a module, the PLL controller provides the following:
• Glitch-free transitions (on changing PLL settings)
• Domain clocks alignment
• Clock gating
• PLL bypass
• PLL power down
The various clock outputs given by the PLL controller are as follows:
• Domain clocks: SYSCLKn
• Bypass domain clock: SYSCLKBP
• Auxiliary clock from reference clock: AUXCLK
Various dividers that can be used are as follows:
• Pre-PLL divider: PREDIV
• Post-PLL divider: POSTDIV
• SYSCLK divider: PLLDIV1, …, PLLDIVn
• SYSCLKBP divider: BPDIV
Multipliers supported are as follows:
• PLL multiplier control: PLLM

3.7 Power and Sleep Controller (PSC)
In the DM355 system, the Power and Sleep Controller (PSC) is responsible for managing transitions of
system power on/off, clock on/off, and reset. A block diagram of the PSC is shown in Figure 3-5. Many of
the operations of the PSC are transparent to software, such as power-on-reset operations. However, the
PSC provides you with an interface to control several important clock and reset operations.
The PSC includes the following features:
• Manages chip power-on/off, clock on/off, and resets
• Provides a software interface to:
– Control module clock ON/OFF
– Control module resets
• Supports IcePick emulation features: power, clock, and reset

3.9 Pin Multiplexing
PRODUCT PREVIEW
The DM355 makes extensive use of pin multiplexing to accommodate the large number of peripheral
functions in the smallest possible package. In order to accomplish this, pin multiplexing is controlled using
a combination of hardware configuration (at device reset) and software control. No attempt is made by the
DM355 hardware to ensure that the proper pin muxing has been selected for the peripherals or interface
mode being used, thus proper pin muxing configuration is the responsibility of the board and software
designers. An overview of the pin multiplexing is shown in Table 3-12.

3.9.1
Hardware Controlled Pin Multiplexing
Use the Asynchronous EMIF configuration pins (AECFG[3:0]) for hardware pin mux control. AECFG[3:0]
control the partitioning of the AEMIF addresses and GPIOs at reset, which allows you to properly
configure the number of AEMIF address pins required by the boot device while unused addresses pins are
available as GPIOs. These settings may be changed by software after reset by programming the PinMux2
register The PinMux2 register is in the System Control Module. As shown in Table 3-13, the number of
address bits enabled on the AEMIF is selectable from 0 to 16. Pins that are not assigned to another
peripheral and not enabled as address signals become GPIOs (except EM_A[2:1]). The enabled address
signals are always contiguous from EM_BA[1] upwards; bits cannot be skipped. The exception to this are
EM_A[2:1]. These signals (can be used to) represent the ALE and CLE signals for the NAND Flash mode
of the AEMIF and are always enabled. Note that EM_A[0] does not represent the lowest AEMIF address
bit. DM355 supports only 16-bit and 8-bit data widths for the AEMIF. In 16-bit mode, EM_BA[1] represents
the LS address bit (the half-word address) and EM_BA[0] represents the MS address bit (A[14]). In 8-bit
mode, EM_BA[1:0] represent the 2 LS address bits. Note that additional selections are available by
programming the PinMux2 register in software after boot. Note that AECFG selection of ‘0010’ selects
OneNAND interface. The AEMIF needs to operate in the half-rate mode (full_rate = 0) to meet frequency
requirements. Software should not change the PINMUX2 register setting to affect the AEMIF rate
operation. A soft reset of the AEMIF should be performed any time a rate change is made.

Software Controlled Pin Multiplexing
All pin multiplexing options are configurable by software via pin mux registers that reside in the System
Control Module. The PinMux0 Register controls the Video In muxing, PinMux1 register controls Video Out
signals, PinMux2 register controls AEMIF signals, PinMux3 registers control the multiplexing of the GIO
signals, the PinMux4 register controls the SPI and MMC/SD0 signals. Refer to the ARM Subsystem User's
Guide for complete descriptions of the pin mux registers.
3.10 Device Reset
There are five types of reset in DM355. The types of reset differ by how they are initiated and/or by their
effect on the chip. Each type is briefly described in Table 3-14 and further described in the ARM
Subsystem Guide.

3.11 Default Device Configurations
NOTE
Default configuration is the configuration immediately after POR, warm reset, and max
reset and just before the boot process begins. The boot ROM updates the configuration.
See Section 3.12 for more information on the boot process.
3.11.1 Device Configuration Pins
The device configuration pins are described in Table 3-15. The device configuration pins are latched at
reset and allow you to configure all of the following options at reset:
• ARM Boot Mode
• Asynchronous EMIF pin configuration
These pins are described further in the following sections.
NOTE
The device configuration pins are multiplexed with AEMIF pins. After the device
configuration pins are sampled at reset, they automatically change to function as AEMIF
pins. Pin multiplexing is described in Section 3.8.

3.11.2 PLL Configuration
After POR, warm reset, and max reset, the PLLs and clocks are set to their default configurations. The
PLLs are in bypass mode and disabled by default. This means that the input reference clock at MXI1
(typically 24 MHz) drives the chip after reset. For more information on device clocking, see Section 3.5
and Section 3.6. The default state of the PLLs is reflected in the default state of the register bits in the
PLLC registers. Refer the the ARM Subsystem User's Guide for PLLC register descriptions.
3.11.3 Power Domain and Module State Configuration
PRODUCT PREVIEW
Only a subset of modules are enabled after reset by default. Table 3-16 shows which modules are
enabled after reset. Table 3-16 as shows that the following modules are enabled depending on the
sampled state of the device configuration pins: EDMA (CC and TC0), AEMIF, MMC/SD0, UART0, and
Timer0. For example, UART0 is enabled after reset when the device configuration pins (BTSEL[1:0] = 11 Enable UART) select UART boot mode. For more information on module configuration refer to the ARM
Subsystem User's Guide.

3.11.4 ARM Boot Mode Configuration
The input pins BTSEL[1:0] determine whether the ARM will boot from its ROM or from the Asynchronous
EMIF (AEMIF). When ROM boot is selected (BTSEL[1:0] = 00, 10, or 11), a jump to the start of internal
ROM (address 0x0000: 8000) is forced into the first fetched instruction word. The embedded ROM boot
loader code (RBL) then performs certain configuration steps, reads the BOOTCFG register to determine
the desired boot method, and branches to the appropriate boot routine (i.e., a NAND, MMC/SD, or UART
loader routine).
If AEMIF boot is selected (BTSEL[1:0] = 01), a jump to the start of AEMIF (address 0x0200: 0000) is
forced into the first fetched instruction word. The ARM then continues executing from external
asynchronous memory using the default AEMIF timings until modified by software.
NOTE
For AEMIF boot, the OneNAND must be connected to the first AEMIF chip select space
(EM_CE0). Also, the AEMIF does not support direct execution from NAND Flash.
Boot modes are further described in Section 3.12.
3.11.5 AEMIF Configuration
3.11.5.1 AEMIF Pin Configuration
The input pins AECFG[3:0] determine the AEMIF configuration immediately after reset. Use AECFG[3:0]
to properly configure the pins of the AEMIF. Refer to the section on pin multiplexing in Section 3.9.
Also, see the Asynchronous External Memory Interface (AEMIF) Peripheral Reference Guide (SPRUEE8)
for more information on the AEMIF.
3.11.5.2 AEMIF Timing Configuration
When AEMIF is enabled, the wait state registers are reset to the slowest possible configuration, which is
88 cycles per access (16 cycles of setup, 64 cycles of strobe, and 8 cycles of hold). Thus, with a 24 MHz
clock at MXI, the AEMIF is configured to run at 6 MHz/88 which equals approximately 68 kHz by default.
See the Asynchronous External Memory Interface (AEMIF) Peripheral Reference Guide for more
information on the AEMIF.
3.12 Device Boot Modes
The DM355 ARM can boot from either Async EMIF (AEMIF/OneNand) or from ARM ROM, as determined
by the setting of the device configuration pins BTSEL[1:0]. The BTSEL[1:0] pins can define the ROM boot
mode further as well.

The boot selection pins (BTSEL[1:0]) determine the ARM boot process. After reset (POR, warm reset, or
max reset), ARM program execution begins in ARM ROM at 0x0000: 8000, except when BTSEL[1:0] = 01,
indicating AEMIF (AEMIF/OneNand) boot. See Section 3.11.1 for information on the boot selection pins.
DM355’s ARM ROM boot loader (RBL) executes when the BOOTSEL[1:0] pins indicate a condition other
than the normal ARM EMIF boot.
• If BTSEL[1:0] = 01 - Asynchronous EMIF (AEMIF or NOR Flash) boot. This mode is handled by
hardware control and does not involve the ROM. In the case of OneNAND, the user is responsible for
putting any necessary boot code in the OneNAND's boot page. This code shall configure the AEMIF
module for the OneNAND device. After the AEMIF module is configured, booting will continue
immediately after the OneNAND’s boot page with the AEMIF module managing pages thereafter.
Furthermore, in case of Fast Boot from AEMIF/OneNAND, the user is responsible for checking the
state of the FASTBOOT bit in the BOOTCFG register in the System Module in order to respond
properly by executing any required device init, bringing mDDR out of self-refresh, and branching to
user entry point in mDDR.
• The RBL supports 3 distinct boot modes:
– BTSEL[1:0] = 00 - ARM NAND Boot
– BTSEL[1:0] = 10 - ARM MMC/SD Boot
– BTSEL[1:0] = 11 - ARM UART Boot
• If NAND boot fails, then MMC/SD mode is tried.
• If MMC/SD boot fails, then MMC/SD boot is tried again.
• If UART boot fails, then UART boot is tried again.
• RBL uses GIO61 to indicate boot status (can use to blink LED):
– After reset, GIO61 is initially driven low (e.g LED off)
– If NAND boot fails and then MMC/SD boot fails, then GIO61 shall toggle at 4Hz while MMC/SD
boot is retried.
– If MMC/SD boot fails, then GIO61 shall toggle at 4Hz while MMC/SD boot is retried
– If UART boot fails, then GIO61 shall toggle at 2Hz while UART boot is retried
– When boot is successful, just before program control is given to UBL, GIO61 is driven high (e.g.
LED on)
– DM355 Timer0 shall be used to accurately toggle GIO61 at 4Hz and 2Hz
• ARM ROM Boot - NAND Mode
– No support for a full firmware boot. Instead, copies a second stage user boot loader (UBL) from
NAND flash to ARM internal RAM (AIM) and transfers control to the user-defined UBL.
– Support for NAND with page sizes up to 2048 bytes.
– Support for magic number error detection and retry (up to 24 times) when loading UBL
– Support for up to 30KB UBL (32KB IRAM - ~2KB for RBL stack)
– Optional, user-selectable, support for use of DMA and I-cache during RBL execution (i.e.,while
loading UBL)
– Supports booting from 8-bit NAND devices (16-bit NAND devices are not supported)
– Supports 4-bit ECC (1-bit ECC is not supported)
– Supports NAND flash that requires chip select to stay low during the tR read time
– Supports Fast Boot option, which allows you to quickly boot and recover from a low power mode
• ARM ROM Boot - MMC/SD Mode
– No support for a full firmware boot. Instead, copies a second stage Uwer Boot Loader (UBL) from
MMC/SD to ARm Internal RAM (AIM) and transfers control to the user software.
– Support for MMC/SD Native protocol (MMC/SD SPI protocol is not supported)
– Support for descriptor error detection and retry (up to 24 times) when loading UBL

The is designed for minimal power consumption. There are two components to power consumption: active
power and leakage power. Active power is the power consumed to perform work and scales with clock
frequency and the amount of computations being performed. Active power can be reduced by controlling
the clocks in such a way as to either operate at a clock setting just high enough to complete the required
operation in the required timeline or to run at a clock setting until the work is complete and then drastically
cut the clocks (e.g. to PLL Bypass mode) until additional work must be performed. Leakage power is due

unavoidable while power is applied and scales roughly with the operating junction temperatures. Leakage
power can only be avoided by removing power completely from a device or subsystem. The DM355

3.14 64-Bit Crossbar Architecture
The DM355 uses a 64-bit crossbar architecture to control access between device processors, subsystems
and peripherals. It includes an EDMA Controller consisting of a DMA Transfer Controller (TC) and a DMA
Channel Controller (CC). The TC provides two DMA channels for transfer between slave peripherals. The
CC provides a user and event interface to the EDMA system. It includes up to 64 event channels to which
all system synchronization events can be mapped and 8 auto submit “quick” channels (QDMA). In most
ways, these channels are identical. A channel refers to a specific ‘event’ that can cause a transfer to be
submitted to the TC as a Transfer Request.
3.14.1 Crossbar Connections
PRODUCT PREVIEW
There are five transfer masters (TCs have separate read and write connections) connected to the
crossbar; ARM, the Video Processing Sub-system (VPSS), the master peripherals (USB), and two EDMA
transfer controllers. These can be connected to four separate slave ports; ARM, the DDR EMIF, and CFG
bus peripherals. Not all masters may connect to all slaves. Connection paths are indicated by √ at
intersection points shown in Table 3-18

PRODUCT PREVIEW
The EDMA Controller consists of two major blocks: the Transfer Controller (TC) and the Channel
Controller (CC). The CC is a highly flexible Channel Controller that serves as the user interface and event
interface for the EDMA system. The CC supports 64-event channels and 8 QDMA channels. The CC
consists of a scalable Parameter RAM (PaRAM) that supports flexible ping-pong, circular buffering,
channel-chaining, auto-reloading, and memory protection.

SPRS463 – SEPTEMBER 2007
DMA Channels: Can be triggered by: " External events (for example, ASP TX Evt and RX Evt), " Software
writing a '1' to the given bit location, or channel, of the Event Set register, or, " Chaining to other DMAs.
QDMA: The Quick DMA (QDMA) function is contained within the CC. DM355 implements 8 QDMA
channels. Each QDMA channel has a selectable PaRAM entry used to specify the transfer. A QDMA
transfer is submitted immediately upon writing of the "trigger" parameter (as opposed to the occurrence of
an event as with EDMA). The QDMA parameter RAM may be written by any Config bus master through
the Config Bus and by DMAs through the Config Bus bridge.
QDMA Channels: Triggered by a configuration bus write to a designated 'QDMA trigger word'. QDMAs
allow a minimum number of linear writes (optimized for GEM IDMA feature) to be issued to the CC to
force a series of transfers to take place.
3.14.2.1
EDMA Channel Synchronization Events
PRODUCT PREVIEW
The EDMA supports up to 64 EDMA channels which service peripheral devices and external memory.
Table 3-19 lists the source of EDMA synchronization events associated with each of the programmable
EDMA channels. For the device, the association of an event to a channel is fixed; each of the EDMA
channels has one specific event associated with it. These specific events are captured in the EDMA event
registers (ER, ERH) even if the events are disabled by the EDMA event enable registers (EER, EERH).
For more detailed information on the EDMA module and how EDMA events are enabled, captured,
processed, linked, chained, and cleared, etc., see the Document Support section for the Enhanced Direct
Memory Access (EDMA) Controller Reference Guide.

In addition to the events shown in this table, each of the 64 channels can also be synchronized with the transfer completion or
intermediate transfer completion events. For more detailed information on EDMA event-transfer chaining, see the Document Support
section for the Enhanced Direct Memory Access (EDMA) Controller Reference Guide.
The total number of EDMA events in DM355 exceeds 64, which is the maximum value of the EDMA module. Therefore, several events
are multiplexed and you must use the register EDMA_EVTMUX in the System Control Module to select the event source for multiplexed
events. Refer to the ARM Subsystem Guide for more information on the System Control Module register EDMA_EVTMUX.

All voltage values are with respect to VSS.
Clamp current flows from an input or output pad to a supply rail through a clamp circuit or an intrinsic diode. Positive current results from
an applied input or output voltage that is more than 0.5 V higher (more positive) than the supply voltage, VDD/VDD_PLL*/VDD_USB/VDD_DDR
for dual-supply macros. Negative current results from an applied voltage that is more than 0.5 V less (more negative) than the VSS
voltage..

The data sheet provides timing at the device pin. For output timing analysis, the tester pin electronics and its
transmission line effects must be taken into account. A transmission line with a delay of 2 ns or longer can be used to
produce the desired transmission line effect. The transmission line is intended as a load only. It is not necessary to
add or subtract the transmission line delay (2 ns or longer) from the data sheet timings.
Input requirements in this data sheet are tested with an input slew rate of < 4 Volts per nanosecond (4 V/ns) at the
device pin.

3. Power off 1.3 V: CVDD, VDDA_PLL1/2, VDDD13_USB, VDDA13_USB
You may power-off the 1.8 V and 3.3 V power supplies simultaneously.
Note that when booting the DM355 from OneNAND, you must ensure that the OneNAND device is ready
with valid program instructions before the DM355 attempts to read program instructions from it. In
particular, before you release DM355 reset, you must allow time for OneNAND device power to stabilize
and for the OneNAND device to complete its internal copy routine. During the internal copy routine, the
OneNAND device copies boot code from its internal non-volatile memory to its internal boot memory
section. Board designers typically achieve this requirement by design of the system power and reset
supervisor circuit. Refer to your OneNAND device datasheet for OneNAND power ramp and stabilization
times and for OneNAND boot copy times.
5.3.1.1
Power-Supply Design Considerations
Core and I/O supply voltage regulators should be located close to the DM355 to minimize inductance and
resistance in the power delivery path. Additionally, when designing for high-performance applications
utilizing the device, the PC board should include separate power planes for core, I/O, and ground, all
bypassed with high-quality low-ESL/ESR capacitors.
5.3.1.2
Power-Supply Decoupling
In order to properly decouple the supply planes from system noise, place as many capacitors (caps) as
possible close to . These caps need to be close to the power pins, no more than 1.25 cm maximum
distance to be effective. Physically smaller caps, such as 0402, are better because of their lower parasitic
inductance. Proper capacitance values are also important. Small bypass caps (near 560 pF) should be
closest to the power pins. Medium bypass caps (220 nF or as large as can be obtained in a small
package) should be next closest. TI recommends no less than 8 small and 8 medium caps per supply be
placed immediately next to the BGA vias, using the "interior" BGA space and at least the corners of the
"exterior".
Larger caps for each supply can be placed further away for bulk decoupling. Large bulk caps (on the order
of 100 μF) should be furthest away, but still as close as possible. Large caps for each supply should be
placed outside of the BGA footprint.
Any cap selection needs to be evaluated from a yield/manufacturing point-of-view. As with the selection of
any component, verification of capacitor availability over the product’s production lifetime should be
considered. See also Section 5.5.1 and Section 5.5.2 for additional recommendations on power supplies
for the oscillator/PLL supplies.

5.5 Oscillators and Clocks
has two oscillator input/output pairs (MXI1/MXO1 and MXI2/MXO2) usable with external crystals or
ceramic resonators to provide clock inputs. The optimal frequencies for the crystals are 24 MHz
(MXI1/MXO1) and 27 MHz (MXI2/MXO2). Optionally, the oscillator inputs are configurable for use with
external clock oscillators. If external clock oscillators are used, to minimize the clock jitter, a single clean
power supply should power both the and the external oscillator circuit and the minimum CLKIN rise and
fall times must be observed. The electrical requirements and characteristics are described in this section.
The timing parameters for CLKOUT[3:1] are also described in this section. The has three output clock pins
(CLKOUT[3:1]). See Section 3.5 and Section 3.6 for more information on CLKOUT[3:1].

MXI1 (24-MHz) Oscillator
PRODUCT PREVIEW
The MXI1 (typically 24 MHz, can also be 36 MHz) oscillator provides the primary reference clock for the
device. The on-chip oscillator requires an external crystal connected across the MXI1 and MXO1 pins,
along with two load capacitors, as shown in Figure 5-5. The external crystal load capacitors must be
connected only to the oscillator ground pin (VSS_MX1). Do not connect to board ground (VSS). Also, the PLL
power pin (VDDA_PLL1) should be connected to the power supply through a ferrite bead, L1 in the example
circuit shown in Figure 5-5.

5.6 General-Purpose Input/Output (GPIO)
The GPIO peripheral supports the following:
• Up to 104 3.3v GPIO pins, GPIO[103:0]
• Interrupts:
– Up to 10 unique GPIO[9:0] interrupts from Bank 0
– Up to 7 GPIO (bank aggregated) interrupt signals, one from each of the 7 banks of GPIOs
– Interrupts can be triggered by rising and/or falling edge, specified for each interrupt capable GPIO
signal
• DMA events:
– Up to 10 unique GPIO DMA events from Bank 0
– Up to 7 GPIO (bank aggregated) DMA event signals, one from each of the 7 banks of GPIOs
• Set/clear functionality: Firmware writes 1 to corresponding bit position(s) to set or to clear GPIO
signal(s). This allows multiple firmware processes to toggle GPIO output signals without critical section
protection (disable interrupts, program GPIO, re-enable interrupts, to prevent context switching to
anther process during GPIO programming).
• Separate Input/Output registers
• Output register in addition to set/clear so that, if preferred by firmware, some GPIO output signals can
be toggled by direct write to the output register(s).
• Output register, when read, reflects output drive status. This, in addition to the input register reflecting
pin status and open-drain I/O cell, allows wired logic be implemented.

The GPIO peripheral provides general-purpose pins that can be configured as either inputs or outputs.
When configured as an output, a write to an internal register can control the state driven on the output pin.
When configured as an input, the state of the input is detectable by reading the state of an internal
register. In addition, the GPIO peripheral can produce CPU interrupts and EDMA events in different
interrupt/event generation modes. The GPIO peripheral provides generic connections to external devices.
The GPIO pins are grouped into banks of 16 pins per bank (i.e., bank 0 consists of GPIO [0:15]). There
are a total of 7 GPIO banks in the , because the has 104 GPIOs.

5.9 Video Processing Sub-System (VPSS) Overview
The contains a Video Processing Sub-System (VPSS) that provides an input interface (Video Processing
Front End or VPFE) for external imaging peripherals such as image sensors, video decoders, etc.; and an
output interface (Video Processing Back End or VPBE) for display devices, such as analog SDTV
displays, digital LCD panels, HDTV video encoders, etc.
PRODUCT PREVIEW
In addition to these peripherals, there is a set of common buffer memory and DMA control to ensure
efficient use of the DDR2 burst bandwidth. The shared buffer logic/memory is a unique block that is
tailored for seamlessly integrating the VPSS into an image/video processing system. It acts as the primary
source or sink to all the VPFE and VPBE modules that are either requesting or transferring data from/to
DDR2. In order to efficiently utilize the external DDR2 bandwidth, the shared buffer logic/memory
interfaces with the DMA system via a high bandwidth bus (64-bit wide). The shared buffer logic/memory
also interfaces with all the VPFE and VPBE modules via a 128-bit wide bus. The shared buffer
logic/memory (divided into the read & write buffers and arbitration logic) is capable of performing the
following functions. It is imperative that the VPSS utilize DDR2 bandwidth efficiently due to both its large
bandwidth requirements and the real-time requirements of the VPSS modules. Because it is possible to
configure the VPSS modules in such a way that DDR2 bandwidth is exceeded, a set of user accessible
registers is provided to monitor overflows or failures in data transfers.
5.9.1
Video Processing Front-End (VPFE)
The VPFE or Video Processing Front-End block is comprised of the CCD Controller (CCDC), Image Pipe
(IPIPE), Hardware 3A Statistic Generator (H3A), and CFA Multiply Mask / Lens Distortion Module
(CFALD). These modules are described in the sections that follow.
5.9.1.1 CCD Controller (CCDC)
The CCDC is responsible for accepting raw (unprocessed) image/video data from a sensor (CMOS or
CCD). In addition, the CCDC can accept YUV video data in numerous formats, typically from so-called
video decoder devices. In the case of raw inputs, the CCDC output requires additional image processing
to transform the raw input image to the final processed image. This processing can be done either
on-the-fly in the Preview Engine hardware ISP or in software on the ARM and MPEG/JPEG co-processor
subsystems. In parallel, raw data input to the CCDC can also used for computing various statistics (3A,
Histogram) to eventually control the image/video tuning parameters. The CCDC is programmed via control
and parameter registers. DM355 performance is enhanced by its dedicated hard-wired MPEG/JPEG
co-processor (MJCP). The MJCP performs all the computational operations required for JPE and MPEG4
compression. These operations can be invoked using the xDM (xDIAS for Digital Media) APIs. For more
information, refer to the xDIAS-DM (xDIAS for Digital Media) User's Guide (SPRUEC8). The following
features are supported by the CCDC module.
• Support for conventional Bayer pattern, movie mode VGA (e.g. Panasonic/Sony), and Foveon sensor
formats.
• Support for the various movie mode formats is also provided via a data reformatter that transforms
from any specific sensor format to the Bayer format. This data reformatter is internal to the CCDC.
• Generates HD/VD timing signals and field ID to an external timing generator or can synchronize to the
external timing generator.
• Support for progressive and interlaced sensors (hardware support for up to 2 fields and firmware
support for higher number of fields, typically 3-, 4-, and 5-field sensors).
• Support for up to 75 MHz sensor clock
• Support for REC656/CCIR-656 standard (YCbCr 422 format, either 8- or 16-bit).
• Support for YCbCr 422 format, either 8- or 16-bit with discrete H and VSYNC signals.
• Support for up to 14-bit input.
• Support for color space conversion
• Generates optical black clamping signals.
• Support for shutter signal control.

Support for generating output to range from 16-bits to 8-bits wide (8-bits wide allows for 50% saving in
storage area).
Support for down sampling via programmable culling patterns.
Ability to control output to the DDR2 via an external write enable signal.
Support for up to 32K pixels (image size) in both the horizontal and vertical direction.
5.9.1.2 IPIPE - Image Pipe
The hardware Image Pipe (IPIPE) is a programmable hardware image processing module that is
responsible for transforming raw (unprocessed) image/video data from a sensor (CMOS or CCD) into
YCbCr 422 data that is amenable for compression or display. The IPIPE can also be configured to operate
in a resize only mode, which allows YCbCr 422 to be resized without applying the processing of every
module in the IPIPE. Typically, the output of the IPIPE is used for both video compression and displaying
it on an external display device such as a NTSC/PAL analog encoder or a digital LCD. The IPIPE is
programmed via control and parameter registers. The following features are supported by the IPIPE.
• The input interface extracts valid raw data from the CCD raw data, and then various modules in IPIPE
process the raw CCD data.
• The 2D noise filter module reduces impulse noise in the raw data and adjusts the resolution of the
input image.
• The 2D pre-filter adjusts the resolution of the input image and remove line crawl noise.
• The white balance module applies two gain adjustments to the data: a digital gain (total gain) and a
white balance gain.
• The Color Filter Array (CFA) interpolation module implements CFA interpolation. The output from the
CFA interpolation module is always RGB formatted data.
• The RGB2RGB blending module applies a 3x3 matrix transform to the RGB data generated by the
CFA interpolation module.
• The gamma correction module independently applies gamma correction to each RGB component.
Gamma is implemented using a piece-wise linear interpolation approach with a 512 entry look up table
for each color.
• The RGB2YCbCr conversion module applies 3x3 matrix transformation to the RGB data to convert it to
YCbCr data. This module also implements offset.
• The 4:2:2 conversion module applies the chroma low pass filter and down samples Cb and Cr, so that
IPIPE output data is in YCbCr-4:2:2 format.
• The 2D edge enhancer module improves image clarity with luminance non-linear filter. This module
also has contrast and brightness adjustment functions.
• The chroma suppression module reduces faulty-color using luminance (Y) value or high-pass-filtering Y
value. The H-resizer and V-resizer modules resize horizontal and vertical image sizes, respectively.
• The output interface module transfers data from IPIPE to SDRAM, in the form of YCbCr-422 or RGB
(32bit/16bit).
• The histogram function can record histograms of up to 4 distinct areas into up to 256 bins.
• The boxcar function makes 1/8 or 1/16 size (1/64 or 1/256 in area) images.
• The boundary signal calculator makes vectors of row and column summations.
• IPIPE has four different processing paths:

– Case 2: IPIPE reads CCD raw data and stores the ayer data after white balance to SDRAM.
– Case 3: IPIPE reads YCbCr-422 data and apply edge enhance, chroma suppression and Resize to
output YCbCr (or RGB) data to SDRAM.
– Case 4: IPIPE reads CCD raw data and produces Boxcar data.
5.9.1.3 Hardware 3A (H3A)
The H3A module is designed to support the control loops for Auto Focus, Auto White Balance and Auto
Exposure by collecting metrics about the imaging/video data. The metrics are to adjust the various
parameters for processing the imaging/video data. There are 2 main blocks in the H3A module:
• Auto Focus (AF) engine
• Auto Exposure (AE) Auto White Balance (AWB) engine
PRODUCT PREVIEW
The AF engine extracts and filters the red, green, and blue data from the input image/video data and
provides either the accumulation or peaks of the data in a specified region. The specified region is a
two-dimensional block of data and is referred to as a "paxel" for the case of AF.
The AE/AWB Engine accumulates the values and checks for saturated values in a sub sampling of the
video data. In the case of the AE/AWB, the two-dimensional block of data is referred to as a "window".
Thus, other than referring them by different names, a paxel and a window are essentially the same thing.
However, the number, dimensions, and starting position of the AF paxels and the AE/AWB windows are
separately programmable.
The following features are supported by the AF engine:
• Support for input from DDR2 / mDDR SDRAM (in addition to the CCDC port)
• Support for a Peak Mode in a Paxel (a Paxel is defined as a two dimensional block of pixels).
• Accumulate the maximum Focus Value of each line in a Paxel
• Support for an Accumulation/Sum Mode (instead of Peak mode).
• Accumulate Focus Value in a Paxel.
• Support for up to 36 Paxels in the horizontal direction and up to 128 Paxels in the vertical direction.
The number of horizontal paxels is limited by the memory size (and cost), while the vertical number of
paxels is not. Therefore, the number of paxels in horizontal direction is smaller than the number of
paxels in vertical direction.
• Programmable width and height for the Paxel. All paxels in the frame will be of same size.
• Programmable red, green, and blue position within a 2x2 matrix.
• Separate horizontal start for paxel and filtering.
• Programmable vertical line increments within a paxel.
• Parallel IIR filters configured in a dual-biquad configuration with individual coefficients (2 filters with 11
coefficients each). The filters are intended to compute the sharpness/peaks in the frame to focus on.
The following features are supported by the AE/AWB engine:
• Support for input from DDR2 / mDDR SDRAM (in addition to the CCDC port)
• Accumulate clipped pixels along with all non-saturated pixels
• Support for up to 36 horizontal windows.
• Support for up to 128 vertical windows.
• Programmable width and height for the windows. All windows in the frame will be of same size.
• Separate vertical start co-ordinate and height for a black row of paxels that is different than the
remaining color paxels.
• Programmable Horizontal Sampling Points in a window
• Programmable Vertical Sampling Points in a window

This hardware module, CFALD, contains two functions: lens distortion correction and CFA multiply mask.
The two functions share hardware components so only one can operate at a time. Lens geometric
distortion, or barrel distortion, refers to the warping of image contents typically at the corners of a captured
image. This is a common problem in digital photography, so being able to correct the distortion in
hardware enhances the value and competitiveness of a digital camera DSP device. The CFA multiply
mask function takes a down-sampled multiplication mask from external memory, and up-samples it to pixel
resolution to scale the corresponding pixels of a CFA image. CFA multiply mask is useful for lens shading
compensation and scene-dependent lighting adjustment. .
• Lens distortion correction:
– Correct barrel distortion
– Radius-to-magnification-factor table to accommodate various distortion functions via programming
– Configurable center point and horizontal/vertical adjustment
– Separate lookup table for each color to correct chromatic aberration
– Support CFA data format input/output for pre-image-pipe correction
– Support up to 14-bit data input/output
– Support up to 16383 x 16383 image dimension
• CFA multiply mask:
– Multiply mask in 8x8 down-sampled format
– Support 8-bit mask (in U8Q5 format)
– Support up to 14-bit image data input/output
– Support up to 16383 x 16383 image dimension
5.9.1.3.2 Auto Exposure (AE) and Auto White Balance (AWB) Engine
The following features are supported by the Auto Exposure (AE) and Auto White Balance (AWB) Engine.
• Accumulate clipped pixels along with all non-saturated pixels.
• Up to 36 horizontal windows.
• Up to 128 vertical windows.
• Programmable width and height for the windows. All windows in the frame will be of same size.
• Separate vertical start coordinate and height for a black row of paxels that is different than the
remaining color paxels.
• Programmable Horizontal Sampling Points in a window.
• Programmable Vertical Sampling Points in a window.

Video Processing Back-End (VPBE)
The Video Processing Back-End of VPBE module is comprised of the On Screen Display (OSD) module
and the Video Encoder / Digital LCD Controller (VENC/DLCD).
5.9.2.1 On-Screen Display (OSD)
The primary function of the OSD module is to gather and blend video data and display/bitmap data and
then pass it to the Video Encoder (VENC) in YCbCr format. The video and display data is read from
external DDR2/mDDR memory. The OSD is programmed via control and parameter registers. The
following are the primary features that are supported by the OSD.
• Support for two video windows and two OSD bitmapped windows that can be displayed simultaneously
(VIDWIN0/VIDWIN1 and OSDWIN0/OSDWIN1).
• Video windows supports YCbCr data in 422 format from external memory, with the ability to
interchange the order of the CbCr component in the 32-bit word
• OSD bitmap windows support 1/2/4/8 bit width index data of color palette
• In addition one OSD bitmap window at a time can be configured to one of the following:
– YUV422 (same as video data)
– RGB format data in 16-bit mode (R=5bit, G=6bit, B=5bit)
– 24-bit mode (each R/G/B=8bit) with pixel level blending with video windows
• Programmable color palette with the ability to select between a RAM/ROM table with support for 256
colors.
• Support for 2 ROM tables, one of which can be selected at a given time
• Separate enable/disable control for each window
• Programmable width, height, and base starting coordinates for each window
• External memory address and offset registers for each window
• Support for x2 and x4 zoom in both the horizontal and vertical direction
• Pixel-level blending/transparency/blinking attributes can be defined for OSDWIN0 when OSDWIN1 is
configured as an attribute window for OSDWIN0.
• Support for blinking intervals to the attribute window
• Ability to select either field/frame mode for the windows (interlaced/progressive)
• An eight step blending process between the bitmap and video windows
• Transparency support for the bitmap and video data (when a bitmap pixel is zero, there will be no

•
The following restrictions exist in the OSD module.
• If the vertical resize filter is enabled for either of the video windows, the maximum horizontal window
dimension cannot be greater than 720 currently. This is due to the limitation in the size of the line
memory.
• It is not possible to use both of the CLUT ROMs at the same time. However, a window can use RAM
while another uses ROM.
5.9.2.2 Video Encoder / Digital LCD Controller (VENC/DLCD)

The I2C pins SDA and SCL do not feature fail-safe I/O buffers. These pins could potentially draw current when the device is powered
down.
A Fast-mode I2C-bus™ device can be used in a Standard-mode I2C-bus™ system, but the requirement tsu(SDA-SCLH)≥ 250 ns must then
be met. This will automatically be the case if the device does not stretch the LOW period of the SCL signal. If such a device does stretch
the LOW period of the SCL signal, it must output the next data bit to the SDA line tr max + tsu(SDA-SCLH)= 1000 + 250 = 1250 ns
(according to the Standard-mode I2C-Bus Specification) before the SCL line is released.
A device must internally provide a hold time of at least 300 ns for the SDA signal (referred to the VIHmin of the SCL signal) to bridge the
undefined region of the falling edge of SCL.
The maximum th(SDA-SCLL) has only to be met if the device does not stretch the low period [tw(SCLL)] of the SCL signal.
Cb = total capacitance of one bus line in pF. If mixed with HS-mode devices, faster fall-times are allowed.

Digital Media System-on-Chip (DMSoC)
SPRS463 – SEPTEMBER 2007
DM355 includes two separate ASP controllers. The primary use for the audio serial port (ASP) is for audio
interface purposes. The primary audio modes that are supported by the ASP are the AC97 and IIS modes.
In addition to the primary audio modes, the ASP supports general serial port receive and transmit
operation, but is not intended to be used as a high-speed interface. The ASP is backward compatible with
other TI ASPs. The ASP supports the following features:
• Full-duplex communication
• Double-buffered data registers, which allow a continuous data stream
• Independent framing and clocking for receive and transmit
• External shift clock generation or an internal programmable frequency shift clock
• Double-buffered data registers, which allow a continuous data stream
• Independent framing and clocking for receive and transmit
• Direct interface to industry-standard codecs, analog interface chips (AICs), and other serially
connected analog-to-digital (A/D) and digital-to-analog (D/A) devices
• Direct interface to AC97 compliant devices (the necessary multiphase frame synchronization capability
is provided)
• Direct interface to IIS compliant devices
• A wide selection of data sizes, including 8, 12, 16, 20, 24, and 32 bits
• μ-Law and A-Law commanding
• 8-bit data transfers with the option of LSB or MSB first
• Programmable polarity for both frame synchronization and data clocks
• Highly programmable internal clock and frame generation
For more detailed information on the ASP peripheral, see the Documentation Support section for the
Audio Serial Port (ASP) Reference Guide.

PRODUCT PREVIEW
The contains four software-programmable timers. Timer 0, Timer 1, and Timer 3 (general-purpose timers)
can be programmed in 64-bit mode, dual 32-bit unchained mode, or dual 32-bit chained mode. Timer 3
supports additional features over the other timers: external clock/event input, period reload, output event
tied to Real Time Out (RTO) module, external event capture, and timer counter register read reset. Timer
2 is used only as a watchdog timer. Timer 2 is tied to device reset.
• 64-bit count-up counter
• Timer modes:
– 64-bit general-purpose timer mode (Timer 0, 1, 3)
– Dual 32-bit general-purpose timer mode (Timer 0, 1, 3)
– Watchdog timer mode (Timer 2)
• Two possible clock sources:
– Internal clock
– External clock/event input via timer input pins (Timer 3)
• Three possible operation modes:
– One-time operation (timer runs for one period then stops)
– Continuous operation (timer automatically resets after each period)
– Continuous operation with period reload (Timer 3)
• Generates interrupts to the ARM CPU
• Generates sync event to EDMA
• Generates output event to device reset (Timer 2)

Pulse Width Modulator (PWM)
The DM355 contains 4 separate Pulse Width Modulator (PWM) modules. The pulse width modulator
(PWM) feature is very common in embedded systems. It provides a way to generate a pulse periodic
waveform for motor control or can act as a digital-to-analog converter with some external components.
This PWM peripheral is basically a timer with a period counter and a first-phase duration comparator,
where bit width of the period and first-phase duration are both programmable. The Pulse Width Modulator
(PWM) modules support the following features:
• 32-bit period counter
• 32-bit first-phase duration counter
• 8-bit repeat count for one-shot operation. One-shot operation will produce N + 1 periods of the
waveform, where N is the repeat counter value.
• Configurable to operate in either one-shot or continuous mode
• Buffered period and first-phase duration registers
• One-shot operation triggerable by hardware events with programmable edge transitions. (low-to-high or
high-to-low).
• One-shot operation triggerable by the CCD VSYNC output of the video processing subsystem (VPSS),
which allows any of the PWM instantiations to be used as a CCD timer. This allows the DM355 module
to support the functions provided by the DM320 CCD timer feature (generating strobe and shutter
signals).
• One-shot operation generates N+1 periods of waveform, N being the repeat count register value
• Configurable PWM output pin inactive state
• Interrupt and EDMA synchronization events

5.18 IEEE 1149.1 JTAG
The JTAG (1) interface is used for BSDL testing and emulation of the device.
The device requires that both TRST and RESET be asserted upon power up to be properly initialized.
While RESET initializes the device, TRST initializes the device's emulation logic. Both resets are required
for proper operation.
While both TRST and RESET need to be asserted upon power up, only RESET needs to be released for
the device to boot properly. TRST may be asserted indefinitely for normal operation, keeping the JTAG
port interface and device's emulation logic in the reset state.
TRST only needs to be released when it is necessary to use a JTAG controller to debug the device or
exercise the device's boundary scan functionality. Note: TRST is synchronous and must be clocked by
TCK; otherwise, the boundary scan logic may not respond as expected after TRST is asserted.
PRODUCT PREVIEW
RESET must be released only in order for boundary-scan JTAG to read the variant field of IDCODE
correctly. Other boundary-scan instructions work correctly independent of current state of RESET.
For maximum reliability, includes an internal pulldown (PD) on the TRST pin to ensure that TRST will
always be asserted upon power up and the device's internal emulation logic will always be properly
initialized.
JTAG controllers from Texas Instruments actively drive TRST high. However, some third-party JTAG
controllers may not drive TRST high but expect the use of a pullup resistor on TRST.
When using this type of JTAG controller, assert TRST to intialize the device after powerup and externally
drive TRST high before attempting any emulation or boundary scan operations. Following the release of
RESET, the low-to-high transition of TRST must be "seen" to latch the state of EMU1 and EMU0. The
EMU[1:0] pins configure the device for either Boundary Scan mode or Emulation mode. For more detailed
information, see the terminal functions section of this data sheet.

follows:
ICEPick port Default TAP TAP IR bits
--------------------------------------------------------------------------18 no c64x+ 38
17 no ETB 4
26 no ARM926 4
NOTE: This is assuming the EMU 0/1 pins are pulled high
ICEPick Boot Mode upon Power-on Reset
EMU1 EMU0 TAPs in the TDI>TDO path Other Effects
--------------------------------------------------------------------------0 0 ICEPick + default TAP(s)
0 1 ICEPick Reserved
1 0 ICEPick Wait-in-reset
1 1 ICEPick Default condition
NOTES: ICDPick is always in the scan chain
Default TAPs are the ARM and the ETB
Notes: It is highly rrecommended that support for the default condition
be inmpemented. Going forward, TI will be moving to have only the
ICDPick in the scan chain, with no configuration with default TAP(s) is
in the scan chain. Thus, support for ICDPick and the ability to
configure the scan chain will be important.
