TMS320DM6443
Digital Media System on-Chip
SPRS282 – DECEMBER 2005
Description
The TMS320DM6443 (also referenced as DM6443) leverages TI’s Davinci technology to meet the
networked media encode and decode application processing needs of next-generation embedded devices.
The DM6443 enables OEMs and ODMs to quickly bring to market devices featuring robust operating
systems support, rich user interfaces, high processing performance, and long battery life through the
maximum flexibility of a fully integrated mixed processor solution.
The dual-core architecture of the DM6443 provides benefits of both DSP and Reduced Instruction Set
Computer (RISC) technologies, incorporating a high-performance TMS320C64x+ DSP core and an
ARM926EJ-S MPU core.
The ARM926EJ-S is a 32-bit RISC processor core that performs 32-bit or 16-bit instructions and
processes 32-bit, 16-bit, or 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).
The TMS320C64x+™ DSPs are the highest-performance fixed-point DSP generation in the
TMS320C6000™ DSP platform. It is based on an enhanced version of the second-generation
high-performance, advanced very-long-instruction-word (VLIW) architecture developed by Texas
Instruments (TI), making these DSP cores an excellent choice for digital media applications. The C64x is a
code-compatible member of the C6000™ DSP platform. The TMS320C64x+ DSP is an enhancement of
the C64x+ DSP with added functionality and an expanded instruction set.
Any reference to the C64x DSP or C64x CPU also applies, unless otherwise noted, to the C64x+ DSP and
C64x+ CPU, respectively.
With performance of up to 4752 million instructions per second (MIPS) at a clock rate of 594 MHz, the
C64x+ core offers solutions to high-performance DSP programming challenges. The DSP core possesses
the operational flexibility of high-speed controllers and the numerical capability of array processors. The
C64x+ DSP core processor has 64 general-purpose registers of 32-bit word length and eight highly
independent functional units—two multipliers for a 32-bit result and six arithmetic logic units (ALUs). The
eight functional units include instructions to accelerate the performance in video and imaging applications.
The DSP core can produce four 16-bit multiply-accumulates (MACs) per cycle for a total of 2376 million
MACs per second (MMACS), or eight 8-bit MACs per cycle for a total of 4752 MMACS. For more details
on the C64x+ DSP, see the TMS320C64x/C64x+ DSP CPU and Instruction Set Reference Guide
(literature number SPRU732).
The DM6443 also has application-specific hardware logic, on-chip memory, and additional on-chip
peripherals similar to the other C6000 DSP platform devices. The DM6443 core uses a two-level
cache-based architecture. The Level 1 program cache (L1P) is a 256K-bit direct mapped cache and the
Level 1 data cache (L1D) is a 640K-bit 2-way set-associative cache. The Level 2 memory/cache (L2)
consists of an 512K-bit memory space that is shared between program and data space. L2 memory can
be configured as mapped memory, cache, or combinations of the two.
The peripheral set includes: 1 configurable video port; a 10/100 Mb/s Ethernet MAC (EMAC) with a
Management Data Input/Output (MDIO) module; an inter-integrated circuit (I2C) Bus interface; one audio
serial port (ASP); 2 64-bit general-purpose timers each configurable as 2 independent 32-bit timers; 1
64-bit watchdog timer; up to 71-pins of general-purpose input/output (GPIO) with programmable
interrupt/event generation modes, multiplexed with other peripherals; 3 UARTs with hardware
handshaking support on 1 UART; 3 pulse width modulator (PWM) peripherals; and 2 external memory
interfaces: an asynchronous external memory interface (EMIFA) for slower memories/peripherals, and a
higher speed synchronous memory interface for DDR2.

TMS320DM6443
Digital Media System on-Chip

SPRS282 – DECEMBER 2005
The DM6443 includes a Video Processing Sub-System (VPSS) that has a configurable Resizer and Video
Processing Back-End (VPBE) output used for display.
The Resizer accepts image data for separate horizontal and vertical resizing from 1/4x to 4x in increments
of 256/N, where N is between 64 and 1024.
The Video Processing Back-End (VPBE) is comprised of an On-Screen Display Engine (OSD) and a
Video Encoder (VENC). The OSD engine is capable of handling 2 separate video windows and 2 separate
OSD windows. Other configurations include 2 video windows, 1 OSD window, and 1 attribute window
allowing up to 8 levels of alpha blending. The VENC provides four analog DACs that run at 54 MHz,
providing a means for composite NTSC/PAL video, S-Video, and/or Component video output. The VENC
also provides up to 24 bits of digital output to interface to RGB888 devices. The digital output is capable of
8/16-bit BT.656 output and/or CCIR.601 with separate horizontal and vertical syncs.
PRODUCT PREVIEW
The Ethernet Media Access Controller (EMAC) provides an efficient interface between the DM644X MPU
core processor and the network. The DM6443 EMAC support both 10Base-T and 100Base-TX, or 10
Mbits/second (Mbps) and 100 Mbps in either half- or full-duplex mode, with hardware flow control and
quality of service (QOS) support.
The Management Data Input/Output (MDIO) module continuously polls all 32 MDIO addresses in order to
enumerate all PHY devices in the system. Once a PHY candidate has been selected by the MPU, the
MDIO module transparently monitors its link state by reading the PHY status register. Link change events
are stored in the MDIO module and can optionally interrupt the MPU, allowing the MPU to poll the link
status of the device without continuously performing costly MDIO accesses.
The I2C, SPI, USB2.0, and VLYNQ ports allow DM6443 to easily control peripheral devices and/or
communicate with host processors.
The rich peripheral set provides the ability to control external peripheral devices and communicate with
external processors. For details on each of the peripherals, see the related sections later in this document
and the associated peripheral reference guides.
The DM6443 has a complete set of development tools for both the ARM and DSP. These include C
compilers, a DSP assembly optimizer to simplify programming and scheduling, and a Windows™
debugger interface for visibility into source code execution.

• Power and Sleep Controller (PSC)
• System Module
2.3.1
ARM926EJ-S RISC MPU
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:

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.
2.3.3
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
2.3.4
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.
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.
2.3.5
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-EMIFA boot options, such as NAND and UART. 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 0x8000 through 0xFFFF. Placing the
instruction region at 0x0000 is necesssary to allow the ARM Interrupt Vector table to be placed at 0x0000,
as required by the ARM architecture. The internal 16-KB RAM is split into two physical banks of 8KB
each, which allows simultaneous instruction and data accesses to be accomplished if the code and data
are in separate banks.
The ARM926EJ-S has built in DMA support for direct accesses to the ARM internal memory from a nonARM device. Furthermore, 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.
2.3.6
Advanced High-Performance Bus (AHB)
The ARM Subsystem uses the AHB port of the ARM926EJ-S to connect the ARM to the Config bus and
the external memories. Arbiters are employed to arbitrate access to the separate D-AHB and I-AHB by the
Config Bus and the external memories bus.
2.3.7
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 DM644X 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 DM644X 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.

configuring and controlling a variety of system functions. For details and register descriptions for the
System module, see the Device Configurations section and the Documentation Support section of this
document for the ARM Subsystem Guide.
2.3.15
Power Management
DM6443 has several means of managing power consumption. There is extensive use of clock gating,
which reduces the power used by global device clocks and individual peripheral clocks. The DSP power
can be disabled through register settings. Voltage/Frequency scaling can be used to allow the user to
lower the core power supply voltage if the frequency needs for a particular application are lower. Clock
management can be utilized to reduce clock frequencies in order to reduce switching power. For more
details on power management techniques, see the Device Configurations and Peripheral sections of this
document and the Documentation Support section of this document for the ARM Subsystem Guide.
DM6443 gives the programmer full flexibility to use any and all of the previously mentioned capabilities to
customize an optimal power management strategy. Several typical power management scenarios are
described in the following sections.
2.3.15.1
Standby Power Mode
This mode consumes the lowest power, with the minimum set of modules kept alive that are required to
wake up the chip to a higher power mode. DSP and coprocessor subsystems are not powered. The rest of
the chip is powered and clocks are suspended, except for GPIO (interrupts), UARTs, I2C (in slave mode),
and the PWM peripheral. PLLs are operating in bypass mode. 27-MHz clock is the only clock available to
the system. DDR2 clock is suspended and the DDR2 Memory Controller is put into self-refresh mode.
2.3.15.2
Low-Power Mode
This mode is for the ARM to sustain some basic control functions. DSP and coprocessor subsystems are
not powered. The rest of the chip is powered, but most clocks are suspended, except for ARM, GPIO,
UARTs, SPI, I2C, PWMs, and Timers. PLLs are operating in bypass mode. 27-MHz clock is the only clock
available to the system. ARM runs at 13.5 MHz, and handles all peripherals by direct access. DDR2 clock
is suspended and DDR2 Memory Controller is put into self-refresh mode. ARM will not have access to
DDR2 and its caches are either frozen or inaccessible.
2.3.15.3
Active Power Mode
The entire chip is powered. All modules operate at nominal clock frequency. Unused peripherals have
their clocks suspended. Active peripherals have their clocks suspended when unneeded.

DSP Subsystem
The DSP Subsystem includes the following features:
• C64X+ DSP CPU
• 32KB L1 Program (L1P)/Cache (up to 32KB)
• 80KB L1 Data (L1D)/Cache (up to 32KB)
• 64KB Unified Mapped RAM/Cache (L2)
• Little endian
C64X+ DSP CPU Description
The C64x+ Central Processing Unit (CPU) consists of eight functional units, two register files, and two
data paths as shown in Figure 2-1. The two general-purpose register files (A and B) each contain
32 32-bit registers for a total of 64 registers. The general-purpose registers can be used for data or can be
data address pointers. The data types supported include packed 8-bit data, packed 16-bit data, 32-bit
data, 40-bit data, and 64-bit data. Values larger than 32 bits, such as 40-bit-long or 64-bit-long values are
stored in register pairs, with the 32 LSBs of data placed in an even register and the remaining 8 or
32 MSBs in the next upper register (which is always an odd-numbered register).
The eight functional units (.M1, .L1, .D1, .S1, .M2, .L2, .D2, and .S2) are each capable of executing one
instruction every clock cycle. The .M functional units perform all multiply operations. The .S and .L units
perform a general set of arithmetic, logical, and branch functions. The .D units primarily load data from
memory to the register file and store results from the register file into memory.
The C64x+ CPU extends the performance of the C64x core through enhancements and new features.
Each C64x+ .M unit can perform one of the following each clock cycle: one 32 x 32 bit multiply, one 16 x
32 bit multiply, two 16 x 16 bit multiplies, two 16 x 32 bit multiplies, two 16 x 16 bit multiplies with
add/subtract capabilities, four 8 x 8 bit multiplies, four 8 x 8 bit multiplies with add operations, and four
16 x 16 multiplies with add/subtract capabilites (including a complex multiply). There is also support for
Galois field mutiplication for 8-bit and 32-bit data. Many communications algorithms such as FFTs and
modems require complex multiplication. The complex multiply (CMPY) instruction takes for 16-bit inputs
and produces a 32-bit real and a 32-bit imaginary output. There are also complex multiplies with rounding
capability that produces one 32-bit packed output that contain 16-bit real and 16-bit imaginary values. The
32 x 32 bit multiply instructions provide the extended precision necessary for audio and other
high-precision algorithms on a variety of signed and unsigned 32-bit data types.
The .L or (Arithmetic Logic Unit) now incorporates the ability to do parallel add/subtract operations on a
pair of common inputs. Versions of this instruction exist to work on 32-bit data or on pairs of 16-bit data
performing dual 16-bit add and subtracts in parallel. There are also saturated forms of these instructions.
The C64x+ core enhances the .S unit in several ways. In the C64x core, dual 16-bit MIN2 and MAX2
comparisons were only available on the .L units. On the C64x+ core they are also available on the .S unit
which increases the performance of algorithms that do searching and sorting. Finally, to increase data
packing and unpacking throughput, the .S unit allows sustained high performance for the quad 8-bit/16-bit
and dual 16-bit instructions. Unpack instructions prepare 8-bit data for parallel 16-bit operations. Pack
instructions return parallel results to output precision including saturation support.
Other new features include:
• SPLOOP - A small instruction buffer in the CPU that aids in creation of software pipelining loops where
multiple iterations of a loop are executed in parallel. The SPLOOP buffer reduces the code size
associated with software pipelining. Futhermore, loops in the SPLOOP buffer are fully interruptible.
• Compact Instructions - The native instruction size for the C6000 devices is 32 bits. Many common
instructions such as MPY, AND, OR, ADD, and SUB can be expressed as 16 bits if the C64x+
compiler can restrict the code to use certain registers in the register file. This compression is
performed by the code generation tools.

Instruction Set Enhancement - As noted above, there are new instructions such as 32-bit
multiplications, complex multiplications, packing, sorting, bit manipulation, and 32-bit Galois field
multiplication.
Exceptions Handling - Intended to aid the programmer in isolating bugs. The C64x+ CPU is able to
detect and respond to exceptions, both from internally detected sources (such as illegal op-codes) and
from system events (such as a watchdog time expiration).
Privilege - Defines user and supervisor modes of operation, allowing the operating system to give a
basic level of protection to sensitive resources. Local memory is divided into multiple pages, each with
read, write, and execute permissions.
Time-Stamp Counter - Primarily targeted for Real-Time Operating System (RTOS) robustness, a
free-running time-stamp counter is implemented in the CPU which is not sensitive to system stalls.

Device and Development-Support Tool 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., TMX320DM6443ZWT). 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.
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 still is undefined. Only qualified production devices are
to be used.
TI device nomenclature also includes a suffix with the device family name. This suffix indicates the
package type (for example, ZWT), the temperature range (for example, "Blank" is the commercial
temperature range), and the device speed range in megahertz (for example, "Blank" is the default
[594-MHz DSP, 297-MHz ARM9]).
Figure 2-7 provides a legend for reading the complete device name for any TMS320DM644x SoC platform
member.

Power Considerations
Global device power domains are controlled by the Power and Sleep Controller, except as shown in the
following sections.
3.2.1
Power Configurations at Reset
As described in the DM6443 Power and Clock Domains section, the DM6443 has two power domains:
Always On and DSP. There is a shorting switch between the two power domains that must be opened
when the DSP domain is powered off and closed when the DSP domain is powered on.
The CHP_SHRTSW register, shown in Figure 3-1, controls the shorting switch between the device
always-on and DSP power domains. This switch should be enabled after powering-up the DSP domain.
Setting the DSPPWRON bit to '1’ closes (enables) the switch and enables the DSP power domain. The
default switch value is determined by the DSP_BT configuration input. If DSP self boot is selected
(DSP_BT=1), the DSP will be powered-up and DSPPWRON will be set to a value of '1'. For ARM boot
operation (DSP_BT=0), DSPPWRON will be set to the disable value of '0' and must be set by the ARM
before the DSP domain power is turned on.

3.3.1
Clock Configurations after Power-On/Hard Reset
As described in the DM6443 Power and Clock Domains section, the DM6443 system includes two
separate power domains and up to forty-one separate modules. The "AlwaysOn" power domain is always
on when the chip is on. The "AlwaysOn" domain is powered by the CVDD pin of the DM6443 chip. The
majority of the DM6443 modules lie within the "AlwaysOn" power domain. The DSP Subsystem lies in a
separate domain that is not always on. This domain is referred to as the "DSP" domain. The DSP power
domain is powered by the CVDDDSP pin of the device.
Table 3-4 shows the state of each module after a chip Power-On/Hard Reset. The default state of the
"DSP" power domain and the DSP module is determined by the DSP boot select pin
(COUT3/B6/DSP_BT). If the DSP is selected to self boot (COUT3/B6/DSP_BT = 1) at reset, the "DSP"
domain will power up by default.

3.3.1.1.2
Module States
A module can be in one of four states – Disable, Enable, SwRstDisable, or SyncReset. As shown in
Table 3-5, the four states correspond to combinations of module reset asserted or de-asserted and
module clock on or off.

The module states are defined as follows:
• Enable: A module in the enable state has its module reset de-asserted and its clock on.
• Disable: A module in the disable state has its module reset de-asserted and its clock off. This state
is typically used for disabling a module clock for power savings. The DM6443 is designed in full static
CMOS, so when you stop a module clock, the modules state is retained. When the clock is restarted,
the module resumes operating from the point it was stopped.
• SyncRst: A module in the SyncRst state has its module reset asserted and its clock on. After initial
power-on, most modules are by default in the SyncRst state.
• SwRstDisable: A module in the SwRstDisable state has its module reset asserted and its clock off.
3.3.1.2
DAC and Video Encoder Clocks
The DAC and Video Encoder Clocks within the Video Processing SubSystem (VPSS) are controlled via

ARM Boot
The DM6443 ARM can boot from EMIFA, internal ROM (NAND) or UART as determined by the setting of
the BTSEL[1:0] pins. The BTSEL[1:0] pins are read by the ARM ROM Boot Loader (RBL) to further define
the ROM boot mode. The ARM boot modes are summarized in Table 3-9.

Up to 14 K-bytes secondary boot loader through UART.
When the BTSEL[1:0] pins are set to the ARM EMIFA External Boot ("01"), the ARM immediately begins
executing code from the EMIFA EM_CS2 memory space (0x0200 0000). When the BTSEL[1:0] pins
indicate a condition other than the ARM EMIFA External Boot (!01), the RBL begins execution.
ARM NAND Boot mode has the following features:
• No support for a full firmware boot. Instead, copies a secondary User Boot Loader (UBL) from NAND
flash to ARM Internal RAM (AIM) and transfers control to the user software.
• Support for NAND with page sizes up to 2048 bytes.
• Support for error correction when loading UBL
• Support for up to 14KB UBL
• Optional, user selectable, support for use of DMA, I-cache, and PLL enable while loading UBL
ARM UART Boot mode has the following features:
• No support for a full firmware boot. Instead, loads a secondary UBL via UART to AIM and transfers
control to the user software.

3.4.3
DSP Boot
For C64x+ booting, the state of the DSP_BT pin is sampled at reset. If DSP_BT is low, the MPU will be
the master of C64x+ and control booting (Host Boot mode). If DSP_BT is high, the C64x+ will boot itself
coming out of device reset (Self-Boot mode). Table 3-10 shows a summary of the DSP boot modes.

3.4.3.1
Host-Boot Mode
In host boot mode, the ARM is the master and controls the reset and boot of the C64x+. The C64x+ DSP
remains powered-off after device reset. The ARM is responsible for enabling power to the C64x+ and
releasing it from reset (PSC MMR bits: MDCTL[39].LRST and MRSTOUT1.MRSTz[39]). Prior to releasing
the C64x+ reset, the ARM must program the address from which the C64x+ will begin execution in the
DSPBOOTADDR register.
3.4.3.2
Self-Boot Mode
In self-boot mode, the C64x+ power domain is turned on and the C64x+ DSP is released from reset
without ARM intervention. The C64x+ begins execution from the default EMIFA address (0x4220 0000)
contained within the DSPBOOTADDR register. The C64x+ begins execution with instruction (L1P) cache
enabled.

Peripheral Selection at Device Reset
PRODUCT PREVIEW
As briefly mentioned in Table 3-11, the state of the AEAW[4:0] pins captured at reset configures the
number of EMIFA address pins required for device boot. These values are stored in the AEAW field of the
PINMUX0 register. At reset, this provides proper addressing for external boot. Unused address pins are
available for use as GPIO. The register settings are software programmable after reset. Table 3-12,
Table 3-13, and Table 3-14 show the AEAW[4:0] bit settings and the corresponding multiplexing for
EMIFA address and GPIO pins.
The number of EMIFA address bits enabled is configurable from 0 to 23. EM_BA[1] and EM_A[21:0] pins
that are not assigned to another peripheral and not enabled as address signals become GPIO pins. The
enabled address pins are always contiguous from EM_BA[1] upwards and address bits cannot be skipped.
The exception to this are the EM_A[2:1] pins. EM_A[2:1] are usable as the ALE and CLE signals for the
NAND Flash mode of EMIFA and are always enabled as EMIFA pins. If an address width of 0 is selected,
this still allows a NAND Flash to be accessed. Also, selecting an address width of 2, 3, or 4 (AEAW[4:0] =
00010, 00011, or 00100) always results in 4 address outputs. For these and other address bit enable
settings, see Table 3-12, Table 3-13, and Table 3-14.

Configurations After Reset
The following sections give the details on configuring the device after reset.
3.6.1
Switched Central Resource (SCR) Bus Priorities
Prioritization within the switched central resource (SCR) is selected to be either fixed or dynamic. Dynamic
prioritization is based on the incoming epriority signals from each master. On DM6443, only the C64x+,
VPSS, and EDMA masters actually generate epriority values. For all other masters, the value is
programmed in the chip-level MSTPRI0/1 registers. The register bit fields and default priority levels for
DM6443 bus masters are shown in Table 3-15. The priority levels should be tuned to obtain the best
system performance for a particular application. Details on the MSTPRI0/1 registers are given in
Figure 3-6 and Figure 3-7.

3.6.2
Multiplexed Pin Configurations
There are numerous multiplexed pins that are shared by more than one peripheral. Some of these pins
are configured by external pullup/pulldown resistors only at reset, and others are configured by software.
As described in detail in Section 3.5.1 and Section 3.5.2, hardware configurable multiplexed pins are
programmed by external pullup/pulldown resistors at reset to set the initial functionality of pins for use by a
single peripheral. After reset, software configurable multiplexed pins are programmable through Memory
Mapped Registers (MMR) to allow the switching of pin functionalities during run-time. See Section 3.6.3
for more details on the register settings.
A summary of the pin multiplexing is shown in Table 3-16. The EMAC peripheral shares pins with the 3.3V
GPIO pins. The VLYNQ pins overlap upper EMIFA address pins resulting in a reduced EMIFA address
range as the VLYNQ width is increased. The ATA peripheral shares data lines and some control signals
with EMIFA. The ATA DMA pins are multiplexed with UART1. The ASP, UART0/1/2, SPI, I2C, and
PWM0/1/2 all default to GPIO pins when not enabled. The VPBE function of the VPSS requires additional
pins to implement the RGB888 mode. These are multiplexed with GPIOs.

Peripheral Selection After Device Reset
After device reset, the PINMUX0 and PINMUX1 registers are software programmable to allow multiplexing
of shared device pins between peripherals, as given in the Terminal Functions section. Section 3.6.4,
Section 3.6.5, and Section 3.6.6 identify the register settings necessary to configure specific multiplexed
functions and show the primary (default) function after reset.
3.6.4
PINMUX0 Register Description
The PINMUX0 pin multiplexing register controls which peripheral is given ownership over shared pins
among EMAC, LCD, RGB888, RGB666, ATA, VLYNQ, EMIFA, and GPIO peripherals. The register format
is shown in Figure 3-8 and bit field descriptions are given in Table 3-17. More details on the PINMUX0 pin
muxing fields are given in Section 3.6.6. A value of "1" enables the secondary or tertiary pin function.

ATA, EMIFA, UART1, SPI, and GPIO Pin Multiplexing
The ATA peripheral shares pins with the EMIFA and UART1 as seen in Table 3-24. If ATA pin
functionality is enabled by setting the ATAEN bit field, the ATA module will drive the EMIFA data and
control pins. Enabling UART1 disables the use of the ATA DMARQ and DMACK signals and thus only
allows the ATA module to use PIO mode. The ATA HDDIR buffer direction control bit field works in
conjunction with the HDIREN enable bit field to allow the ATA pins to still be used as a GPIO or SPI_EN1
if the buffer is not being used (i.e. for Compact Flash). This multiplexing is shown in Table 3-25. When
ATAEN=0 and HDIREN=1 it indicates that the ATA interface has been disabled so that the EMIFA can be
used, but the ATA buffers are still present. HDDIR is driven low in this situation to ensure that the ATA
buffers drive away from DM644X and don’t cause bus contention with the EMIFA. Note that switching
between EMIFA and ATA (clearing or setting ATAEN) must be carefully performed to prevent bus
contention. Since the ATA device can be a bus master, software must ensure that all outstanding DMA
requests have completed before clearing the ATAEN bit.

VLYNQ, EMIFA, and GPIO Pin Multiplexing
Table 3-26 and Table 3-27 show the VLYNQ pin control and multiplexing. If VLYNQ is disabled
(VLYNQEN=0), the AECS5 and AECS4 bits select between the GPIO[8] / EMIFA EM_CS5 and GPIO[9] /
EMIFA EM_CS4 functions, and the AEAW field determines the partitioning between GPIO and the upper
EMIFA address pins. If VLYNQ is enabled (VLYNQEN=1), VLYNQ_CLOCK, VLYNQ_TXD0, and
VLYNQ_RXD0 are always selected. The VLYNQ_SCRUN function is only enabled if VLYNQEN=1 and
VLSCREN=1 (VLSCREN overrides AECS4). The remaining VLYNQ TX/RX pins are selected based on
the VLYNQWD value. Unselected VLYNQ TX/RX pins will function as either GPIO or EMIFA address
based on the AEAW value.

UART, ATA, and GPIO Pin Multiplexing
Each UART has independent pin multiplexing control bits in the PINMUX1 register.
Setting the UART1 bit enables UART1 transmit and receive pin functionality. Since these are shared with
the ATA DMA handshake signals, enabling UART1 effectively disables the ATA DMA mode. However,
ATA PIO mode is still supported with UART1 enabled. This is shown in Table 3-33. If the ATA module is
not enabled, the pins are always configured for use by UART1.

Emulation Control
The flexibility of the DM644x architecture allows either the ARM or DSP to control the various peripherals
(setup registers, service interrupts, etc.). While this assignment is purely a matter of software convention,
during an emulation halt it is necessary for the device to know which peripherals are associated with the
halting processor so that only those modules receive the suspend signal. This allows peripherals
associated with the other (unhalted) processor to continue normal operation. The SUSPSRC register
indicates the emulation suspend source for those peripherals which support emulation suspend. The
SUSPSRC register format is shown in Figure 3-10. Brief details on the peripherals which correspond to
the register bits is given in Table 3-35. When the associated SUSPSRC bit is ‘0’, the peripheral’s
emulation suspend signal is controlled by the ARM emulator and when set to ‘1’ it is controlled by the DSP
emulator.

This pin is an internal LDO output and connected via 1 µF capacitor to USB_VSSA1P2LDO.
Future variants of TI SOC devices may operate at voltages ranging from 0.9 V to 1.4 V to provide a range of system power/performance
options. TI highly recommends that users design-in a supply that can handle multiple voltages within this range (i.e., 1.0 V, 1.05 V,
1.1 V, 1.14 V, 1.2, 1.26 V with ± 3% tolerances) by implementing simple board changes such as reference resistor values or input pin
configuration modifications. Not incorporating a flexible supply may limit the system's ability to easily adapt to future versions of TI SOC
devices.
Oscillator ground must be kept separate from other grounds and connected directly to the crystal load capacitor ground.
DDR_VREF is expected to equal 0.5DVDDR2 of the transmitting device and to track variations in the DVDDR2.

Timing Parameters and Board Routing Analysis
The timing parameter values specified in this data sheet do not include delays by board routings. As a
good board design practice, such delays must always be taken into account. Timing values may be
adjusted by increasing/decreasing such delays. TI recommends utilizing the available I/O buffer
information specification (IBIS) models to analyze the timing characteristics correctly. To properly use IBIS
models to attain accurate timing analysis for a given system, see the Using IBIS Models for Timing
Analysis application report (literature number SPRA839). If needed, external logic hardware such as
buffers may be used to compensate any timing differences.

Power Supplies

For more information regarding TI's power management products and suggested devices to power TI
DSPs, visit www.ti.com/dsppower.
5.3.1
Power-Supply Sequencing
Note: This power sequencing information is preliminary and subject to change.
Currently, DM6443 devices do not require specific power sequencing between the core supply and the I/O
supply. However, systems should be designed to ensure that neither supply is powered up for extended
periods of time(>1 second) if the other supply is below the proper operating voltage.
5.3.1.1
Power-Supply Design Considerations
Core and I/O supply voltage regulators should be located close to the DSP (or DSP array) to minimize
inductance and resistance in the power delivery path. Additionally, when designing for high-performance
applications utilizing the DM6443 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 DM6443. Assuming 0603 caps, the user should be able to fit a total of 60 caps, 30 for
the core supplies and 30 for the I/O supplies. These caps need to be close to the DM6443 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.

DM6443 Power and Clock Domains
DM6443 includes two separate power domains: "Always On" and "DSP". The "Always On" power domain
is always on when the chip is on. The "Always On" domain is powered by the VDD pins of the DM6443.
The majority of the DM6443's modules lie within the "Always On" power domain. A separate domain called
the "DSP" domain houses the C64x+. The "DSP" domain is not always on. The "DSP" power domain is
powered by the CVDDDSP pins of the DM6443. Table 5-1 provides a listing of the DM6443 power and clock
domains.
Two primary reference clocks are required for the DM6443 device. These can either be crystal input or
driven by external oscillators. A 27-MHz crystal is recommended for the system PLLs, which generate the
internal clocks for the ARM, DSP, coprocessors, peripherals (including imaging peripherals), and EDMA3.
The recommended 27-MHz input enables the use of the video DACs to drive NTSC/PAL television signals
at the proper frequencies. A 24-MHz crystal is also required if the USB peripheral is to be used. For
further description of the DM6443 clock domains, see Table 5-2 and Figure 5-4.

Power and Sleep Controller (PSC)
The Power and Sleep Controller (PSC) controls DM6443 device power by turning off unused power
domains or gating off clocks to individual peripherals/modules. The PSC consists of a Global PSC (GPSC)
and a set of Local PSCs (LPSCs). The GPSC contains memory mapped registers, power domain control,
PSC interrupt control, and a state machine for each peripheral/module. An LPSC is associated with each
peripheral/module and provides clock and reset control. The GPSC controls all of DM6443’s LPSCs. The
ARM Subsystem does not have an LPSC module. ARM sleep mode is accomplished through the wait for
interrupt instruction. The LPSCs for DM6443 are shown in Table 5-3. The PSC Register memory map is
given in Table 5-4. For more details on the PSC, see the Documentation Support section for the ARM
Subsystem User's Guide.

Description
System reset
Software (register bit)
This is a soft reset that maintains memory contents and
does not affect clocks or power states.
C64x+ Local reset
Software (register bit)
MMR controls the C64x+ reset input. This is used for
control of C64x+ reset by the ARM. The C64x+ Slave
DMA port is still alive when in local reset.
Warm reset is activated by driving the RESET pin active low, while TRST is inactive high. This does not
reset test or ARM emulation logic. An ARM emulator session will stay alive during warm reset, but a
C64x+ emulator session will not.
Maximum reset is initiated by the emulator or the watchdog timer and the reset effects are the same as a
warm reset. The emulator initiates a maximum reset via the ICEPICK module. When the watchdog timer
counter reaches zero, this will initiate a maximum reset to recover from a runaway condition. Both of the
maximum reset initiators can be masked by the ARM emulator.
System reset is initiated by the emulator and is a soft reset. Memory contents are maintained. Test,
emulation, clock, and power control logic are unaffected. The emulator initiates a system reset via the
C64x+ emulation logic, or through ICECRUSHER. Both of these reset initiators are non-maskable resets.
The C64x+ DSP has an internal reset input that allows a host to control it. This reset is configured through
a MMR bit (MDCTL[39].LRSTz) in the PSC module. When in C64x+ local reset, the slave DMA port on
C64x+ will remain active and the internal memory will be accessible.
Refer to the ARM Subsystem User's Guide for details on reset control/status registers.
For information on peripheral selection at the rising edge of RESET, see the Device Configuration section
of this data manual.

For proper RESET operation, the RSV5 pin must be driven low or tied directly to Vss at all times and the user must not switch values
throughout device operation.
BTSEL[1:0], DSP_BT, and AEAW[4:0] are the boot configuration pins during device reset.
C = MXI/CLKIN cycle time in ns. For example, when MXI/CLKIN frequency is 27 MHz, use C = 37.037 ns.

PRODUCT PREVIEW
Power-on-reset (POR) is the global chip reset and it affects test, emulation, and other circuitry. It is
invoked by driving the RESET pin active low while TRST is held low. A POR is required to place DM6443
into a known good initial state. POR can be asserted prior to ramping the core and I/O voltages or after
the core and I/O voltages have reached their proper operating conditions. As a best practice, RESET
should be asserted (held low) during power-up. Prior to deasserting RESET (low-to-high transition), the
core and I/O voltages should be at their proper operating conditions and if an external 27 MHz oscillator is
used on the MXI/CLKIN pin, the external clock should also be running at the correct frequency.

Oscillators
DM6443 has two oscillator input/output pairs (MXI/MXO and M24XI/M24XO) usable with external crystals
or ceramic resonators to provide clock inputs. The optimal frequencies for the crystals are 27 MHz
(MXI/MXO) and 24 MHz (M24XI/M24XO). Optionally, the oscillator inputs are configurable for use with
external oscillators.

Clock PLLs
There are two independently controlled PLLs on DM6443. PLL1 generates the frequencies required for the
DSP, ARM, DMA, VPFE, and other peripherals. PLL2 generates the frequencies required for the DDR2
interface and the VPBE in certain modes. The recommended reference clock for both PLLs is the 27-MHz
crystal input. The USB2.0 PHY contains a third PLL embedded within it and the 24-MHz oscillator is its
reference clock source. This particular PLL is only usable for USB operation, and is discussed further in
the TMS320DM6443 DMSoC Universal Serial Bus (USB) Controller User's Guide (see the Documentation
Support section).
A summary of the PLL controller registers is shown in Table 5-11. Refer to the ARM Subsystem User's
Guide for more details.

Clock PLL Considerations with External Clock Sources
If the internal oscillator is bypassed, to minimize the clock jitter a single clean power supply should power
both the DM6443 device and the external clock oscillator circuit. The minimum CLKIN rise and fall times
should also be observed. For the input clock timing requirements, see the input and output clocks
electricals section.
Rise/fall times, duty cycles (high/low pulse durations), and the load capacitance of the external clock
source must meet the device requirements in this data sheet (see the electrical characteristics over
recommended ranges of supply voltage and operating case temperature table and the input and output
clocks electricals section).

The MXI/CLKIN frequency and PLL multiply factor should be chosen such that the resulting clock frequency is within the specific range
for CPU operating frequency. For example, for a -594 speed device with a 27 MHz CLKIN frequency, the PLL multiply factor should be ≤
22.
The reference points for the rise and fall transitions are measured at VIL MAX and VIH MIN.
For more details on the PLL multiplier factors, see the Documentation Support section for ARM Subsystem User's Guide.

Interrupts
The DM6443 device has a large number of interrupts to service the needs of its many peripherals and
subsystems. Both the ARM and C64x+ are capable of servicing these interrupts. All of the device
interrupts are routed to the ARM interrupt controller with only a limited set routed to the C64x+ interrupt
controller. The interrupts can be selectively enabled or disabled in either of the controllers. In typical
applications, the ARM handles most of the peripheral interrupts and grants control, to the C64x+, of
interrupts that are relevant to DSP algorithms. Also, the ARM and DSP can communicate with each other
through interrupts.
5.7.1
MPU Interrupts
PRODUCT PREVIEW
The ARM9 MPU core supports 2 direct interrupts: FIQ and IRQ. The DM6443 ARM interrupt controller
prioritizes up to 64 interrupt requests from various peripherals and subsystems, which are listed in
Table 5-16, and interrupts the MPU. Each interrupt is programmable for up to 8 levels of priority. There
are 6 levels for IRQ and 2 levels for FIQ. Interrupts at the same priority level are serviced in order by the
MPU Interrupt Number, with the lowest number having the highest priority. Table 5-17 shows the ARM
interrupt controller registers and memory locations. For more details on ARM interrupt control, see the
Documentation Support section for the ARM Subsystem User's Guide.

DSP Interrupts
The C64x+ DSP interrupt controller combines device events into 12 prioritized interrupts. The source for
each of the 12 CPU interrupts is user programmable and is listed in Table 5-18. Also, the interrupt
controller controls the generation of the CPU exception, NMI, and emulation interrupts and the generation
of AEG events. Table 5-19 summarizes the C64x+ interrupt controller registers and memory locations. For
more details on DSP interrupt control, see the Documentation Support section for the DSP Subsystem
User's Guide.

ARM/DSP Communication Interrupts
The INTGEN register is used for generating interrupts between the ARM and DSP. The INTGEN register
format is shown in Figure 5-14. Table 5-20 describes the register bit fields. The ARM may generate an
interrupt to the DSP by setting one of the four INTDSP[3:0] bits or the INTNMI bit. The interrupt bit
automatically self clears and the corresponding DSP[3:0]STAT or NMISTAT bit is automatically set to
indicate that the interrupt was generated. After servicing the interrupt, the DSP clears the status bit by
writing ‘0’. The ARM may poll the status bit to determine when the DSP has completed servicing the
interrupt. The DSP may generate an interrupt to the ARM in the same manner using the INTARM[1:0] bits
and monitor ARM interrupt servicing via the ARM[1:0]STAT bits.

General-Purpose Input/Output (GPIO)
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]).
PRODUCT PREVIEW
The DM6443 GPIO peripheral supports the following:
• Up to 54 1.8v GPIO pins, GPIO[0:53]
• Up to 17 3.3v GPIO pins, GPIO3V[0:16] (GPIO[54:70])
• Interrupts:
– Up to 8 unique GPIO[0:7] interrupts from Bank 0
– 5 GPIO bank (aggregated) interrupt signals from each of the 5 banks of GPIOs
– Interrupts can be triggered by rising and/or falling edge, specified for each interrupt capable GPIO
signal
• DMA events:
– Up to 8 unique GPIO DMA events from Bank 0
– 5 GPIO bank (aggregated) DMA event signals from each of the 5 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 memory map for the GPIO registers is shown in Table 5-21. For more detailed information on GPIOs,
see the Documentation Support section for the General-Purpose Input/Output (GPIO) Reference Guide.

EDMA Channel Synchronization Events
The EDMA supports up to 64 EDMA channels which service peripheral devices and external memory.
Table 5-25 lists the source of EDMA synchronization events associated with each of the programmable
EDMA channels. For the DM6443 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.

DM6443 supports several memory and external device interfaces, including:
• Asynchronous EMIF (EMIFA) for interfacing to NOR Flash, SRAM, etc.
• NAND Flash
• ATA/CF
5.10.1
Asynchronous EMIF (EMIFA)
5.10.1.1
NAND (NAND, SmartMedia, xD)
The EMIFA interface provides both the asynchronous EMIF and NAND interfaces. Four chip selects are
provided and each are individually configurable to provide either EMIFA or NAND support. The NAND
features supported are as follows.
• NAND flash on up to 4 asynchronous chip selects.
• 8 and 16-bit data bus widths.
• Programmable cycle timings.
• Performs ECC calculation.
• NAND Mode also supports SmartMedia/SSFDC (Solid State Floppy Disk Controller) and xD memory
cards
• ARM ROM supports booting of the DM6443 ARM processor from NAND flash located at CS0
The memory map for EMIFA and NAND registers is shown in Table 5-29. For more details on the EMIFA
and NAND interfaces, see the Documentation Support for the DM6443 Asynchronous External Memory
Interface (EMIF) User's Guide.

DDR2 Memory Controller
The DDR2 Memory Controller is a dedicated interface to DDR2 SDRAM. It supports JESD79D-2A
standard compliant DDR2 SDRAM Devices and can interface to either 16-bit or 32-bit DDR2 SDRAM
devices. For details on the DDR2 Memory Controller, see the Document Support section.
DDR2 SDRAM plays a key role in a DaVinci-based system. Such a system is expected to require a
significant amount of high-speed external memory for:
• Buffering of input image data from sensors or video sources
• Intermediate buffering for processing/resizing of image data in the VPFE
• Numerous OSD display buffers
• Intermediate buffering for large raw Bayer data image files while performing image processing
functions
• Buffering for intermediate data while performing video encode and decode functions
• Storage of executable code for both the ARM and DSP
A memory map of the DDR2 Memory Controller registers is shown in Table 5-32.

In addition, the Host IDE Controller supports multiword DMA and Ultra DMA data transfers between
external IDE/ATAPI devices and a system memory bus interface. The ATA timing and control registers are
compatible to the Intel register set in the PIIX family. The ATA perpheral has full scatter gather DMA
capability, which is compatible with Intel scatter gather DMA function on the PIIX chipset.

Video Processing Sub-System (VPSS) Overview
The DM6443 Video Processing Sub-System (VPSS) provides a Video Processing Front End (VPFE) input
interface for external imaging peripherals (i.e., image sensors, video decoders, etc.) and a Video
Processing Back End (VPBE) output interface for display devices, such as analog SDTV displays, digital
LCD panels, HDTV video encoders, etc.
Note: The VPSS module is supported with Linux Application Peripheral Interfaces (APIs) commonly used
by video application developers. The VPSS Back-End (VPBE) uses FBDev/DirectFB as the APIs. Certain
functionalities within the VPBE have not been implemented in the FBDev/DirectFB APIs. For
modes/functions not implemented in software, it is user's responsibility to modify the software drivers/APIs.
The VPSS register memory mapping is shown in Table 5-41.

Video Processing Back-End (VPBE)
The Video Processing Back-End (VPBE) consists of the On-Screen Display (OSD) module, the Video
Encoder (VENC) including the Digital LCD (DLCD) and Analog (i.e., DAC) interfaces. The video encoder
generates analog video output. The DLCD controller generates digital RGB/YCbCr data output and timing
signals.
The VPBE register memory mapping is shown in Table 5-45.

On-Screen Display (OSD)
The major function of the OSD module is to gather and blend video data and display/bitmap data before
feeding it to the Video Encoder (VENC) in YCbCr format. The video and display data is read from an
external memory, typically DDR2. The OSD is programmed via control and parameter registers. The
following are the primary features that are supported by the OSD.
• Simultaneous display of two video windows and two OSD windows (VIDWIN0/VIDWIN1 and
OSDWIN0/OSDWIN1).
– Separate enable 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
– OSDWIN1 can be used as an attribute window for OSDWIN0
– Attribute window blinking intervals
– Field/frame mode for the windows (interlaced/progressive)
– Eight step blending process between the OSD and video windows
– Transparency support for the OSD and video data (when a bitmap pixel is zero, there will be no
blending for that corresponding video pixel)
– Resize from VGA to NTSC/PAL (640x480 to 720x576) for both the OSD and video windows
– Reads in YCbCr data in 422 format from external memory, with the capability for swapping the
order of the CbCr component in the 32-bit word (this is relevant to the two video windows)
– Support for a ping-pong buffer scheme that can be used for VIDWIN0 (allows for video data to be
accessed from two different locations in DDR2)
– Each OSD window (either one, but not both at the same time) is capable of reading in RGB data
(16-bit data with six bits for the green and five bits each for the red and blue colors) instead of
bitmap data in YCbCr format restricted to a maximum of 8-bits
– The OSD bitmap data width is selectable between 1, 2, 4, or 8-bits.
– Each OSD window supports 16 entries for the bitmap (to index into a 256 entry RAM/ROM CLUT
table).
– Indirect support for 24-bit RGB input data (which will be transformed into 16-bit YCbCr video
window data) via the wrapper interface in the VPBE.
• Support for a rectangular cursor window and a programmable background color selection.
– Programmable color palette with the ability to select between a RAM/ROM table with support for
256 colors.
– The width, height, and color of the cursor is programmable.
– The display priority is: Rectangular-Cursor > OSDWIN1 > OSDWIN0 > VIDWIN1 > VIDWIN0 >
background color
• Support for attenuation of the YCbCr values for the REC601 standard.

The following restrictions exist in the OSD module.
• Both the OSD windows and VIDWIN1 should be fully contained inside VIDWIN0.
• When one of the OSD windows is set in RGB mode, it cannot overlap with VIDWIN1.
• The OSD cannot support more than 256 color entries in the CLUT RAM/ROM. Some applications
require higher number of entries, and one workaround is to use VIDWIN1 as an overlay mimicking the
OSD window. Another option is to use the RGB mode for one of the OSD windows which allows for a
total of 16-bits for the R, G, and B colors (64K colors).
• The OSD can only read YCbCr in 422 interleaved format for the video windows. Other formats, either
color separate storage or 444/420 interleaved data is not supported.
• If the vertical resize filter is enabled for either of the video windows, the maximum horizontal window
dimension cannot be greater than 720 currently.
• It is not possible to use both of the CLUT ROMs at the same time. However, one window can use
RAM while another uses ROM.
• The 24-bit RGB input mode is only valid for one of the two video windows (programmable) and does
not apply to the OSD windows.
The OSD register memory mapping is shown in Table 5-46.

pF
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.

CLKRP = CLKXP = FSRP = FSXP = 0. If polarity of any of the signals is inverted, then the timing references of that signal are also
inverted.
Minimum delay times also represent minimum output hold times.
Minimum CLKR/X cycle times must be met, even when CLKR/X is generated by an internal clock source. Minimum CLKR/X cycle times
are based on internal logic speed; the maximum usable speed may be lower due to EDMA limitations and AC timing requirements.
P = 1/DSP CPU clock frequency in ns. For example, when running parts at 594 MHz, use P = 1.68 ns.
C = H or L
S = sample rate generator input clock = 4P if CLKSM = 1 (P = 1/CPU clock frequency)
S = sample rate generator input clock = Not Supported if CLKSM = 0 (no CLKS pin on DM6443)
H = CLKX high pulse width = (CLKGDV/2 + 1) * S if CLKGDV is even
H = (CLKGDV + 1)/2 * S if CLKGDV is odd or zero
L = CLKX low pulse width = (CLKGDV/2) * S if CLKGDV is even
L = (CLKGDV + 1)/2 * S if CLKGDV is odd or zero
CLKGDV should be set appropriately to ensure the ASP bit rate does not exceed the maximum limit (see footnote above).
Extra delay from CLKX high to DX valid applies only to the first data bit of a device, if and only if DXENA = 1 in SPCR.
if DXENA = 0, then D1 = D2 = 0
if DXENA = 1, then D1 = 4P, D2 = 8P
Extra delay from FSX high to DX valid applies only to the first data bit of a device, if and only if DXENA = 1 in SPCR.

Ethernet Media Access Controller (EMAC)
The Ethernet Media Access Controller (EMAC) provides an efficient interface between DM6443 and the
network. The DM6443 EMAC support both 10Base-T and 100Base-TX, or 10 Mbits/second (Mbps) and
100 Mbps in either half- or full-duplex mode, with hardware flow control and quality of service (QOS)
support.
The EMAC controls the flow of packet data from the DM6443 device to the PHY. The MDIO module
controls PHY configuration and status monitoring.
For the DM6443 Ethernet Media Access Controller (EMAC) / Management Data Input/Output (MDIO)
Module Reference Guide which describes the DM6443 EMAC peripheral in detail, see the Documentation
Support section . For a list of supported registers and register fields, see Table 5-73 [Ethernet MAC

Both the EMAC and the MDIO modules interface to the DSP through a custom interface that allows
efficient data transmission and reception. This custom interface is referred to as the EMAC control
module, and is considered integral to the EMAC/MDIO peripheral. The control module is also used to
multiplex and control interrupts.

Management Data Input/Output (MDIO)
The Management Data Input/Output (MDIO) module continuously polls all 32 MDIO addresses in order to
enumerate all PHY devices in the system.
The Management Data Input/Output (MDIO) module implements the 802.3 serial management interface to
interrogate and control Ethernet PHY(s) using a shared two-wire bus. Host software uses the MDIO
module to configure the auto-negotiation parameters of each PHY attached to the EMAC, retrieve the
negotiation results, and configure required parameters in the EMAC module for correct operation. The
module is designed to allow almost transparent operation of the MDIO interface, with very little
maintenance from the core processor. Only one PHY may be connected at any given time.
For more detailed information on the MDIO peripheral, see the Documentation Support section for the
Ethernet Media Access Controller (EMAC)/Management Data Input/Output (MDIO) Module Reference
Guide. For a list of supported registers and register fields, see Table 5-81 [MDIO Registers] in this data
manual.

IEEE 1149.1 JTAG
The JTAG (1) interface is used for BSDL testing and emulation of the DM6443 device.
The DM6443 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.
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, DM6443 includes an internal pulldown (IPD) 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.

PRODUCT PREVIEW
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.
