FIXED-POINT DIGITAL SIGNAL PROCESSORS
SPRS146N − FEBRUARY 2001 − REVISED MAY 2005
description
The TMS320C64x™ DSPs (including the TMS320C6414, TMS320C6415, and TMS320C6416 devices) are the
highest-performance fixed-point DSP generation in the TMS320C6000™ DSP platform. The TMS320C64x™
(C64x™†) device is based on the second-generation high-performance, advanced VelociTI™
very-long-instruction-word (VLIW) architecture (VelociTI.2™) developed by Texas Instruments (TI), making
these DSPs an excellent choice for multichannel and multifunction applications. The C64x™ is a
code-compatible member of the C6000™ DSP platform.
With performance of up to 5760 million instructions per second (MIPS) at a clock rate of 720 MHz, the C64x
devices offer cost-effective solutions to high-performance DSP programming challenges. The C64x DSPs
possess 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)— with
VelociTI.2™ extensions. The VelociTI.2™ extensions in the eight functional units include new instructions to
accelerate the performance in key applications and extend the parallelism of the VelociTI™ architecture. The
C64x can produce four 16-bit multiply-accumulates (MACs) per cycle for a total of 2880 million MACs per
second (MMACS), or eight 8-bit MACs per cycle for a total of 5760 MMACS. The C64x DSP also has
application-specific hardware logic, on-chip memory, and additional on-chip peripherals similar to the other
C6000™ DSP platform devices.
The C6416 device has two high-performance embedded coprocessors [Viterbi Decoder Coprocessor (VCP)
and Turbo Decoder Coprocessor (TCP)] that significantly speed up channel-decoding operations on-chip. The
VCP operating at CPU clock divided-by-4 can decode over 600 7.95-Kbps adaptive multi-rate (AMR) [K = 9,
R = 1/3] voice channels. The VCP supports constraint lengths K = 5, 6, 7, 8, and 9, rates R = 1/2, 1/3, and 1/4,
and flexible polynomials, while generating hard decisions or soft decisions. The TCP operating at CPU clock
divided-by-2 can decode up to forty-three 384-Kbps or seven 2-Mbps turbo encoded channels (assuming 6
iterations). The TCP implements the max*log-map algorithm and is designed to support all polynomials and
rates required by Third-Generation Partnership Projects (3GPP and 3GPP2), with fully programmable frame
length and turbo interleaver. Decoding parameters such as the number of iterations and stopping criteria are
also programmable. Communications between the VCP/TCP and the CPU are carried out through the EDMA
controller.
The C64x uses a two-level cache-based architecture and has a powerful and diverse set of peripherals. The
Level 1 program cache (L1P) is a 128-Kbit direct mapped cache and the Level 1 data cache (L1D) is a 128-Kbit
2-way set-associative cache. The Level 2 memory/cache (L2) consists of an 8-Mbit memory space that is
shared between program and data space. L2 memory can be configured as mapped memory or combinations
of cache (up to 256K bytes) and mapped memory. The peripheral set includes three multichannel buffered serial
ports (McBSPs); an 8-bit Universal Test and Operations PHY Interface for Asynchronous Transfer Mode (ATM)
Slave [UTOPIA Slave] port (C6415/C6416 only); three 32-bit general-purpose timers; a user-configurable 16-bit
or 32-bit host-port interface (HPI16/HPI32); a peripheral component interconnect (PCI) [C6415/C6416 only];
a general-purpose input/output port (GPIO) with 16 GPIO pins; and two glueless external memory interfaces
(64-bit EMIFA and 16-bit EMIFB‡), both of which are capable of interfacing to synchronous and asynchronous
memories and peripherals.
The C64x has a complete set of development tools which includes: an advanced C compiler with C64x-specific
enhancements, an assembly optimizer to simplify programming and scheduling, and a Windows™ debugger
interface for visibility into source code execution.

† Throughout the remainder of this document, the TMS320C6414, TMS320C6415, and TMS320C6416 shall be referred to as TMS320C64x or
C64x where generic, and where specific, their individual full device part numbers will be used or abbreviated as C6414, C6415, or C6416.
‡ These C64x™ devices have two EMIFs (64-bit EMIFA and 16-bit EMIFB). The prefix “A” in front of a signal name indicates it is an EMIFA signal
whereas a prefix “B” in front of a signal name indicates it is an EMIFB signal. Throughout the rest of this document, in generic EMIF areas of
discussion, the prefix “A” or “B” may be omitted from the signal name.

CPU (DSP core) description
The CPU fetches VelociTI™ advanced very-long instruction words (VLIWs) (256 bits wide) to supply up to eight
32-bit instructions to the eight functional units during every clock cycle. The VelociTI™ VLIW architecture
features controls by which all eight units do not have to be supplied with instructions if they are not ready to
execute. The first bit of every 32-bit instruction determines if the next instruction belongs to the same execute
packet as the previous instruction, or whether it should be executed in the following clock as a part of the next
execute packet. Fetch packets are always 256 bits wide; however, the execute packets can vary in size. The
variable-length execute packets are a key memory-saving feature, distinguishing the C64x CPUs from other
VLIW architectures. The C64x™ VelociTI.2™ extensions add enhancements to the TMS320C62x™ DSP
VelociTI™ architecture. These enhancements include:
Register file enhancements
Data path extensions
Quad 8-bit and dual 16-bit extensions with data flow enhancements
Additional functional unit hardware
Increased orthogonality of the instruction set
Additional instructions that reduce code size and increase register flexibility
The CPU features two sets of functional units. Each set contains four units and a register file. One set contains
functional units .L1, .S1, .M1, and .D1; the other set contains units .D2, .M2, .S2, and .L2. The two register files
each contain 32 32-bit registers for a total of 64 general-purpose registers. In addition to supporting the packed
16-bit and 32-/40-bit fixed-point data types found in the C62x™ VelociTI™ VLIW architecture, the C64x™ register
files also support packed 8-bit data and 64-bit fixed-point data types. The two sets of functional units, along with
two register files, compose sides A and B of the CPU [see the functional block and CPU (DSP core) diagram,
and Figure 1]. The four functional units on each side of the CPU can freely share the 32 registers belonging to
that side. Additionally, each side features a “data cross path”—a single data bus connected to all the registers
on the other side, by which the two sets of functional units can access data from the register files on the opposite
side. The C64x CPU pipelines data-cross-path accesses over multiple clock cycles. This allows the same
register to be used as a data-cross-path operand by multiple functional units in the same execute packet. All
functional units in the C64x CPU can access operands via the data cross path. Register access by functional
units on the same side of the CPU as the register file can service all the units in a single clock cycle. On the C64x
CPU, a delay clock is introduced whenever an instruction attempts to read a register via a data cross path if that
register was updated in the previous clock cycle.
In addition to the C62x™ DSP fixed-point instructions, the C64x™ DSP includes a comprehensive collection of
quad 8-bit and dual 16-bit instruction set extensions. These VelociTI.2™ extensions allow the C64x CPU to
operate directly on packed data to streamline data flow and increase instruction set efficiency.
Another key feature of the C64x CPU is the load/store architecture, where all instructions operate on registers
(as opposed to data in memory). Two sets of data-addressing units (.D1 and .D2) are responsible for all data
transfers between the register files and the memory. The data address driven by the .D units allows data
addresses generated from one register file to be used to load or store data to or from the other register file. The
C64x .D units can load and store bytes (8 bits), half-words (16 bits), and words (32 bits) with a single instruction.
And with the new data path extensions, the C64x .D unit can load and store doublewords (64 bits) with a single
instruction. Furthermore, the non-aligned load and store instructions allow the .D units to access words and
doublewords on any byte boundary. The C64x CPU supports a variety of indirect addressing modes using either
linear- or circular-addressing with 5- or 15-bit offsets. All instructions are conditional, and most can access any
one of the 64 registers. Some registers, however, are singled out to support specific addressing modes or to
hold the condition for conditional instructions (if the condition is not automatically “true”).

CPU (DSP core) description (continued)
The two .M functional units perform all multiplication operations. Each of the C64x .M units can perform two
16 × 16-bit multiplies or four 8 × 8-bit multiplies per clock cycle. The .M unit can also perform 16 × 32-bit multiply
operations, dual 16 × 16-bit multiplies with add/subtract operations, and quad 8 × 8-bit multiplies with add
operations. In addition to standard multiplies, the C64x .M units include bit-count, rotate, Galois field multiplies,
and bidirectional variable shift hardware.
The two .S and .L functional units perform a general set of arithmetic, logical, and branch functions with results
available every clock cycle. The arithmetic and logical functions on the C64x CPU include single 32-bit, dual
16-bit, and quad 8-bit operations.
The processing flow begins when a 256-bit-wide instruction fetch packet is fetched from a program memory.
The 32-bit instructions destined for the individual functional units are “linked” together by “1” bits in the least
significant bit (LSB) position of the instructions. The instructions that are “chained” together for simultaneous
execution (up to eight in total) compose an execute packet. A “0” in the LSB of an instruction breaks the chain,
effectively placing the instructions that follow it in the next execute packet. A C64x™ DSP device enhancement
now allows execute packets to cross fetch-packet boundaries. In the TMS320C62x™/TMS320C67x™ DSP
devices, if an execute packet crosses the fetch-packet boundary (256 bits wide), the assembler places it in the
next fetch packet, while the remainder of the current fetch packet is padded with NOP instructions. In the C64x™
DSP device, the execute boundary restrictions have been removed, thereby, eliminating all of the NOPs added
to pad the fetch packet, and thus, decreasing the overall code size. The number of execute packets within a
fetch packet can vary from one to eight. Execute packets are dispatched to their respective functional units at
the rate of one per clock cycle and the next 256-bit fetch packet is not fetched until all the execute packets from
the current fetch packet have been dispatched. After decoding, the instructions simultaneously drive all active
functional units for a maximum execution rate of eight instructions every clock cycle. While most results are
stored in 32-bit registers, they can be subsequently moved to memory as bytes, half-words, words, or
doublewords. All load and store instructions are byte-, half-word-, word-, or doubleword-addressable.

EDMA channel synchronization events
The C64x EDMA supports up to 64 EDMA channels which service peripheral devices and external memory.
Table 24 lists the source of C64x EDMA synchronization events associated with each of the programmable
EDMA channels. For the C64x 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 (ERL, ERH) even if the events are disabled by the EDMA event enable registers (EERL, EERH). The
priority of each event can be specified independently in the transfer parameters stored in the EDMA parameter
RAM. For more detailed information on the EDMA module and how EDMA events are enabled, captured,
processed, linked, chained, and cleared, etc., see the TMS320C6000 DSP Enhanced Direct Memory Access
(EDMA) Controller Reference Guide (literature number SPRU234).

interrupt sources and interrupt selector
The C64x DSP core supports 16 prioritized interrupts, which are listed in Table 25. The highest-priority interrupt
is INT_00 (dedicated to RESET) while the lowest-priority interrupt is INT_15. The first four interrupts
(INT_00−INT_03) are non-maskable and fixed. The remaining interrupts (INT_04−INT_15) are maskable and
default to the interrupt source specified in Table 25. The interrupt source for interrupts 4−15 can be programmed
by modifying the selector value (binary value) in the corresponding fields of the Interrupt Selector Control
registers: MUXH (address 0x019C0000) and MUXL (address 0x019C0004).

† These pins are muxed with the GPIO port pins and by default these signals function as clocks (CLKOUT4 or CLKOUT6) or McBSP2
clock source (CLKS2). To use these muxed pins as GPIO signals, the appropriate GPIO register bits (GPxEN and GPxDIR) must be
properly enabled and configured. For more details, see the Device Configurations section of this data sheet.
‡ These pins are GPIO pins that can also function as external interrupt sources (EXT_INT[7:4]). Default after reset is EXT_INTx or
GPIO as input-only.
§ For the C6415 and C6416 devices, these GPIO pins are muxed with the PCI peripheral pins. By default, these signals are set up to
no function with both the GPIO and PCI pin functions disabled. For more details on these muxed pins, see the Device Configurations
section of this data sheet. For the C6414 device, the GPIO peripheral pins are not muxed; the C6414 device does not support the
PCI peripheral.

These C64x™ devices have two EMIFs (64-bit EMIFA and 16-bit EMIFB). The prefix “A” in front of a signal name indicates it is
an EMIFA signal whereas a prefix “B” in front of a signal name indicates it is an EMIFB signal. Throughout the rest of this document,
in generic EMIF areas of discussion, the prefix “A” or “B” may be omitted from the signal name.

Configurations section of this data sheet.
For the C6414 device, these McBSP2 and McBSP1 peripheral pins are not muxed; the C6414 device does not support PCI and UTOPIA
peripherals.
‡ The McBSP2 clock source pin (CLKS2, default) is muxed with the GP8 pin. To use this muxed pin as the GP8 signal, the appropriate
GPIO register bits (GP8EN and GP8DIR) must be properly enabled and configured. For more details, see the Device Configurations
section of this data sheet.

DEVICE CONFIGURATIONS
The C6414, C6415, and C6416 peripheral selections and other device configurations are determined by
external pullup/pulldown resistors on the following pins (all of which are latched during device reset):

BEA11 (UTOPIA_EN)
−
PCI_EN (for C6415 or C6416, see Table 27 footnotes)
−
MCBSP2_EN (for C6415 or C6416, see Table 27 footnotes)
The C6414 device does not support the PCI and UTOPIA peripherals; for proper operation of the C6414
device, do not oppose the internal pulldowns (IPDs) on the BEA11, PCI_EN, and MCBSP2_EN pins. (For
IPUs/IPDs on pins, see the Terminal Functions table of this data sheet.)

peripherals selection
Some C6415/C6416 peripherals share the same pins (internally muxed) and are mutually exclusive (i.e., HPI,
general-purpose input/output pins GP[15:9], PCI and its internal EEPROM, McBSP1, McBSP2, and UTOPIA).
The VCP/TCP coprocessors (C6416 only) and other C64x peripherals (i.e., the Timers, McBSP0, and the
GP[8:0] pins), are always available.
UTOPIA and McBSP1 peripherals
The UTOPIA_EN pin (BEA11) is latched at reset. For C6415 and C6416 devices, this pin selects whether
the UTOPIA peripheral or McBSP1 peripheral is functionally enabled (see Table 26).
The C6414 device does not support the UTOPIA peripheral; for proper device operation, do not oppose the
internal pulldown (IPD) on the BEA11 pin.

The PCI_EN pin must be driven valid at all times and the user must not switch values throughout device operation.
The MCBSP2_EN pin must be driven valid at all times and the user can switch values throughout device operation.
‡ The only time McBSP2 is disabled is when both PCI_EN = 1 and MCBSP2_EN = 0. This configuration enables, at reset, the auto-initialization
of the PCI peripheral through the PCI internal EEPROM [provided the PCI EEPROM Auto-Initialization pin (BEA13) is pulled up
(EEAI = 1)]. The user can then enable the McBSP2 peripheral (disabling EEPROM) by dynamically changing MCBSP2_EN to a “1” after the
device is initialized (out of reset).
−
If the PCI is disabled (PCI_EN = 0), the HPI peripheral is enabled and GP[15:9] pins can be programmed
as GPIO, provided the GPxEN and GPxDIR bits are properly configured.
This means all multiplexed HPI/PCI pins function as HPI and all standalone PCI pins (PCBE0 and
XSP_CS) are tied-off (Hi-Z). Also, the multiplexed GPIO/PCI pins can be used as GPIO with the
proper software configuration of the GPIO enable and direction registers (for more details, see
Table 29).
−
If the PCI is enabled (PCI_EN = 1), the HPI peripheral is disabled.
This means all multiplexed HPI/PCI pins function as PCI. Also, the multiplexed GPIO/PCI pins function
as PCI pins (for more details, see Table 29).
−
The MCBSP2_EN pin, in combination with the PCI_EN pin, controls the selection of the McBSP2
peripheral and the PCI internal EEPROM (for more details, see Table 27 and its footnotes).
other device configurations
Table 28 describes the C6414, C6415, and C6416 devices configuration pins, which are set up via external
pullup/pulldown resistors through the specified EMIFB address bus pins (BEA[20:13, 11, 9:7]) and the HD5 pin.
For more details on these device configuration pins, see the Terminal Functions table and the Debugging
Considerations section.

DEVICE CONFIGURATIONS (CONTINUED)
multiplexed pins
Multiplexed pins are pins that are shared by more than one peripheral and are internally multiplexed. Some of
these pins are configured by software, and the others are configured by external pullup/pulldown resistors only
at reset. Those muxed pins that are configured by software can be programmed to switch functionalities at any
time. Those muxed pins that are configured by external pullup/pulldown resistors are mutually exclusive; only
one peripheral has primary control of the function of these pins after reset. Table 29 identifies the multiplexed
pins on the C6414, C6415, and C6416 devices; shows the default (primary) function and the default settings
after reset; and describes the pins, registers, etc. necessary to configure specific multiplexed functions.
debugging considerations
It is recommended that external connections be provided to device configuration pins, including
CLKMODE[1:0], BEA[20:13, 11, 9:7], HD5/AD5, PCI_EN, and MCBSP2_EN. Although internal pullup/pulldown
resistors exist on these pins (except for HD5/AD5), providing external connectivity adds convenience to the user
in debugging and flexibility in switching operating modes.
Internal pullup/pulldown resistors also exist on the non-configuration pins on the BEA bus (BEA[12, 10, 6:1]).
Do not oppose the internal pullup/pulldown resistors on these non-configuration pins with external
pullup/pulldown resistors. If an external controller provides signals to these non-configuration pins, these
signals must be driven to the default state of the pins at reset, or not be driven at all.
For the internal pullup/pulldown resistors on the C6414, C6415, and C6416 device pins, see the terminal
functions table.

MCBSP2_EN pin to enable/disable other peripherals (for more details, see the Device Configurations section of this data sheet).
The C6414 device does not support the PCI peripheral; for proper device operation, do not
oppose the internal pulldown (IPD) on this pin.

device support
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
(i.e., TMS320C6412GTS600) 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, GLZ), the temperature range (for example, blank is the default commercial temperature range),
and the device speed range in megahertz (for example, -6E3 is 600-MHz CPU, 133-MHz EMIFA). Figure 5
provides a legend for reading the complete device name for any TMS320C64x™ DSP generation member.
The ZLZ package, like the GLZ package, is a 532-pin plastic BGA only with lead-free soldered balls. The CLZ
package, like the GLZ package, is a 532-pin plastic BGA only with lead-free bump and lead−free soldered balls.
The ZLZ and CLZ package types are available upon request. For device part numbers and further ordering
information for TMS320C6414/C6415/C6416 in the GLZ, ZLZ and CLZ package types, see the TI website
(http://www.ti.com) or contact your TI sales representative.

clock PLL
Most of the internal C64x™ DSP clocks are generated from a single source through the CLKIN pin. This source
clock either drives the PLL, which multiplies the source clock frequency to generate the internal CPU clock, or
bypasses the PLL to become the internal CPU clock.
To use the PLL to generate the CPU clock, the external PLL filter circuit must be properly designed. Figure 6
shows the external PLL circuitry for either x1 (PLL bypass) or other PLL multiply modes.
To minimize the clock jitter, a single clean power supply should power both the C64x™ DSP 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 DSP 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). Table 30 lists some examples of compatible CLKIN external clock sources:

These clock frequency range values are applicable to a C64x−6E3 speed device. For −5E0 and -7E3 device speed values, see the CLKIN timing
requirements table for the specific device speed.
‡ Use external pullup resistors on the CLKMODE pins (CLKMODE1 and CLKMODE0) to set the C64x device to one of the valid PLL multiply clock
modes (x6 or x12). With internal pulldown resistors on the CLKMODE pins (CLKMODE1, CLKMODE0), the default clock mode is x1 (bypass).
§ Under some operating conditions, the maximum PLL lock time may vary by as much as 150% from the specified typical value. For example, if
the typical lock time is specified as 100 µs, the maximum value may be as long as 250 µs.

triggering, wake-up, and effects
The power-down modes and their wake-up methods are programmed by setting the PWRD field (bits 15−10)
of the control status register (CSR). The PWRD field of the CSR is shown in Figure 10 and described in Table 32.
When writing to the CSR, all bits of the PWRD field should be set at the same time. Logic 0 should be used when
writing to the reserved bit (bit 15) of the PWRD field. The CSR is discussed in detail in the TMS320C6000 CPU
and Instruction Set Reference Guide (literature number SPRU189).

NOTE: The shadowed bits are not part of the power-down logic discussion and therefore are not covered here. For information on these other
bit fields in the CSR register, see the TMS320C6000 CPU and Instruction Set Reference Guide (literature number SPRU189).
Figure 10. PWRD Field of the CSR Register
A delay of up to nine cycles may occur after the instruction that sets the PWRD bits in the CSR before the PD
mode takes effect. As best practice, NOPs should be padded after the PWRD bits are set in the CSR to account
for this delay.
If PD1 mode is terminated by a non-enabled interrupt, the program execution returns to the instruction where
PD1 took effect. If PD1 mode is terminated by an enabled interrupt, the interrupt service routine will be executed
first, then the program execution returns to the instruction where PD1 took effect. In the case with an enabled
interrupt, the GIE bit in the CSR and the NMIE bit in the interrupt enable register (IER) must also be set in order
for the interrupt service routine to execute; otherwise, execution returns to the instruction where PD1 took effect
upon PD1 mode termination by an enabled interrupt.
PD2 and PD3 modes can only be aborted by device reset. Table 32 summarizes all the power-down modes.

EFFECT ON CHIP’S OPERATION
CPU halted (except for the interrupt logic)
Power-down
Power
down mode blocks the internal clock inputs at the
boundary of the CPU, preventing most of the CPU’s logic from
switching. During PD1, EDMA transactions can proceed
between peripherals and internal memory.
Wake by a device reset
Output clock from PLL is halted, stopping the internal clock
structure from switching and resulting in the entire chip being
halted. All register and internal RAM contents are preserved. All
functional I/O “freeze” in the last state when the PLL clock is
turned off.
Wake by a device reset
Input clock to the PLL stops generating clocks. All register and
internal RAM contents are preserved. All functional I/O “freeze” in
the last state when the PLL clock is turned off. Following reset, the
PLL needs time to re-lock, just as it does following power-up.
Wake-up from PD3 takes longer than wake-up from PD2 because
the PLL needs to be re-locked, just as it does following power-up.
—
—
When entering PD2 and PD3, all functional I/O remains in the previous state. However, for peripherals which are asynchronous in nature or
peripherals with an external clock source, output signals may transition in response to stimulus on the inputs. Under these conditions,
peripherals will not operate according to specifications.
C64x power-down mode with an emulator
If user power-down modes are programmed, and an emulator is attached, the modes will be masked to allow
the emulator access to the system. This condition prevails until the emulator is reset or the cable is removed
from the header. If power measurements are to be performed when in a power-down mode, the emulator cable
should be removed.
When the DSP is in power-down mode PD2 or PD3, emulation logic will force any emulation execution
command (such as Step or Run) to spin in IDLE. For this reason, PC writes (such as loading code) will fail. A DSP
reset will be required to get the DSP out of PD2/PD3.
power-supply sequencing
TI DSPs 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.
power-supply design considerations
A dual-power supply with simultaneous sequencing can be used to eliminate the delay between core and I/O
power up. A Schottky diode can also be used to tie the core rail to the I/O rail (see Figure 11).

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 C6000™ platform of DSPs, the PC board should include separate power planes for
core, I/O, and ground, all bypassed with high-quality low-ESL/ESR capacitors.
power-supply decoupling
In order to properly decouple the supply planes from system noise, place as many capacitors (caps) as possible
close to the DSP. Assuming 0603 caps, the user should be able to fit a total of 60 caps, 30 for the core supply
and 30 for the I/O supply. These caps need to be close to the DSP 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 (32 total) be placed
immediately next to the BGA vias, using the “interior” BGA space and at least the corners of the “exterior”.
Eight larger caps (4 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). No less than 4 large caps per supply
(8 total) should be placed outside of the BGA.
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.

IEEE 1149.1 JTAG compatibility statement
The TMS320C6414/15/16 DSP requires that both TRST and RESET be asserted upon power up to be properly
initialized. While RESET initializes the DSP core, TRST initializes the DSP’s emulation logic. Both resets are
required for proper operation.
Note: TRST is synchronous and must be clocked by TCLK; otherwise, BSCAN may not respond as expected
after TRST is asserted.
While both TRST and RESET need to be asserted upon power up, only RESET needs to be released for the
DSP to boot properly. TRST may be asserted indefinitely for normal operation, keeping the JTAG port interface
and DSP’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 DSP or exercise the DSP’s boundary scan functionality. RESET must be released 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, the TMS320C6414/15/16 DSP includes an internal pulldown (IPD) on the TRST pin
to ensure that TRST will always be asserted upon power up and the DSP’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 DSP 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 occur to latch the state of EMU1 and
EMU0. The EMU[1:0] pins configure the device for either Boundary Scan mode or Normal/Emulation mode. For
more detailed information, see the terminal functions section of this data sheet.
Note: The DESIGN_WARNING section of the TMS320C6414/15/16 BSDL file contains information and
constraints regarding proper device operation while in Boundary Scan Mode.
EMIF device speed
The rated EMIF speed, referring to both EMIFA and EMIFB, of these devices only applies to the SDRAM
interface when in a system that meets the following requirements:
−
1 chip-enable (CE) space (maximum of 2 chips) of SDRAM connected to EMIF
−
up to 1 CE space of buffers connected to EMIF
−
EMIF trace lengths between 1 and 3 inches
−
166-MHz SDRAM for 133-MHz operation (applies only to EMIFA)
−
143-MHz SDRAM for 100-MHz operation
Other configurations may be possible, but timing analysis must be done to verify all AC timings are met.
Verification of AC timings is mandatory when using configurations other than those specified above. TI
recommends utilizing I/O buffer information specification (IBIS) to analyze all AC timings.
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).
To maintain signal integrity, serial termination resistors should be inserted into all EMIF output signal lines (see
the Terminal Functions table for the EMIF output signals).

SPRS146N − FEBRUARY 2001 − REVISED MAY 2005
bootmode
The C6414/15/16 device resets using the active-low signal RESET. While RESET is low, the device is held in
reset and is initialized to the prescribed reset state. Refer to reset timing for reset timing characteristics and
states of device pins during reset. The release of RESET starts the processor running with the prescribed device
configuration and boot mode.
The C6414/C6415/C6416 has three types of boot modes:
Host boot
If host boot is selected, upon release of RESET, the CPU is internally “stalled” while the remainder of the
device is released. During this period, an external host can initialize the CPU’s memory space as necessary
through the host interface, including internal configuration registers, such as those that control the EMIF or
other peripherals. For the C6414 device, the HPI peripheral is used for host boot. For the C6415/C6416
device, the HPI peripheral is used for host boot if PCI_EN = 0, and the PCI peripheral is used for host boot if
PCI_EN = 1. Once the host is finished with all necessary initialization, it must set the DSPINT bit in the HPIC
register to complete the boot process. This transition causes the boot configuration logic to bring the CPU
out of the “stalled” state. The CPU then begins execution from address 0. The DSPINT condition is not
latched by the CPU, because it occurs while the CPU is still internally “stalled”. Also, DSPINT brings the CPU
out of the “stalled” state only if the host boot process is selected. All memory may be written to and read by
the host. This allows for the host to verify what it sends to the DSP if required. After the CPU is out of the
“stalled” state, the CPU needs to clear the DSPINT, otherwise, no more DSPINTs can be received.
EMIF boot (using default ROM timings)
Upon the release of RESET, the 1K-Byte ROM code located in the beginning of CE1 is copied to address 0
by the EDMA using the default ROM timings, while the CPU is internally “stalled”. The data should be stored
in the endian format that the system is using. In this case, the EMIF automatically assembles consecutive
8-bit bytes to form the 32-bit instruction words to be copied. The transfer is automatically done by the EDMA
as a single-frame block transfer from the ROM to address 0. After completion of the block transfer, the CPU
is released from the “stalled” state and starts running from address 0.
No boot
With no boot, the CPU begins direct execution from the memory located at address 0. Note: operation is
undefined if invalid code is located at address 0.
reset
A hardware reset (RESET) is required to place the DSP into a known good state out of power-up. The RESET
signal can be asserted (pulled low) 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 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 CLKIN should also be running at the correct frequency.

Future variants of the C641x DSPs 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., 1.2 V, 1.25 V, 1.3 V, 1.35 V, 1.4 V
with ± 3% tolerances) by implementing simple board changes such as reference resistor values or input pin configuration modifications. Examples
of such supplies include the PT4660, PT5500, PT5520, PT6440, and PT6930 series from Power Trends, a subsidiary of Texas Instruments. Not
incorporating a flexible supply may limit the system’s ability to easily adapt to future versions of C641x devices.
§ The absolute maximum ratings should not be exceeded for more than 30% of the cycle period.

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. If needed, external logic hardware such as buffers
may be used to compensate any timing differences.
For inputs, timing is most impacted by the round-trip propagation delay from the DSP to the external device and
from the external device to the DSP. This round-trip delay tends to negatively impact the input setup time margin,
but also tends to improve the input hold time margins (see Table 33 and Figure 15).
Figure 15 represents a general transfer between the DSP and an external device. The figure also represents
board route delays and how they are perceived by the DSP and the external device.

§ These C64x™ devices have two EMIFs (64-bit EMIFA and 16-bit EMIFB). All EMIFA signals are prefixed by an “A” and all EMIFB signals are
prefixed by a “B”. Throughout the rest of this document, in generic EMIF areas of discussion, the prefix “A” or “B” may be omitted.
¶ E = the EMIF input clock (ECLKIN, CPU/4 clock, or CPU/6 clock) period in ns for EMIFA or EMIFB.
# Minimum ECLKIN cycle times must be met, even when ECLKIN is generated by an internal clock source. Minimum ECLKIN times are based
on internal logic speed; the maximum useable speed of the EMIF may be lower due to AC timing requirements. On the 7E3 and 6E3 devices,
133-MHz operation is achievable if the requirements of the EMIF Device Speed section are met. On the 5E0 devices, 100-MHz operation is
achievable if the requirements of the EMIF Device Speed section are met.

To ensure data setup time, simply program the strobe width wide enough. ARDY is internally synchronized. The ARDY signal is only recognized
two cycles before the end of the programmed strobe time and while ARDY is low, the strobe time is extended cycle-by-cycle. When ARDY is
recognized low, the end of the strobe time is two cycles after ARDY is recognized high. To use ARDY as an asynchronous input, the pulse width
of the ARDY signal should be wide enough (e.g., pulse width = 2E) to ensure setup and hold time is met.

These C64x™ devices have two EMIFs (EMIFA and EMIFB). All EMIFA signals are prefixed by an “A” and all EMIFB signals are prefixed by a
“B”. Throughout the rest of this document, in generic EMIF areas of discussion, the prefix “A” or “B” may be omitted [e.g., the programmable
synchronous interface access signals are shown as generic (SADS/SRE, SOE, and SWE) instead of ASADS/ASRE, ASOE, and ASWE (for
EMIFA) and BSADS/BSRE, BSOE, and BSWE (for EMIFB)].
‡ The following parameters are programmable via the EMIF CE Space Secondary Control register (CExSEC):
− Read latency (SYNCRL): 0-, 1-, 2-, or 3-cycle read latency
− Write latency (SYNCWL): 0-, 1-, 2-, or 3-cycle write latency
− CEx assertion length (CEEXT): For standard SBSRAM or ZBT SRAM interface, CEx goes inactive after the final command has been issued
(CEEXT = 0). For synchronous FIFO interface with glue, CEx is active when SOE is active (CEEXT = 1).
− Function of SADS/SRE (RENEN): For standard SBSRAM or ZBT SRAM interface, SADS/SRE acts as SADS with deselect cycles
(RENEN = 0). For FIFO interface, SADS/SRE acts as SRE with NO deselect cycles (RENEN = 1).
− Synchronization clock (SNCCLK): Synchronized to ECLKOUT1 or ECLKOUT2

§ PDT signal is only asserted when the EDMA is in PDT mode (set the PDTS bit to 1 in the EDMA options parameter RAM). For PDT read, data
is not latched into EMIF. The PDTRL field in the PDT control register (PDTCTL) configures the latency of the PDT signal with respect to the data
phase of a read transaction. The latency of the PDT signal for a read can be programmed to 0, 1, 2, or 3 by setting PDTRL to 00, 01, 10, or 11,
respectively. PDTRL equals 00 (zero latency) in Figure 27.

§ The EKxHZ bits in the EMIF Global Control register (GBLCTL) determine the state of the ECLKOUTx signals during HOLDA. If EKxHZ = 0,
ECLKOUTx continues clocking during Hold mode. If EKxHZ = 1, ECLKOUTx goes to high impedance during Hold mode, as shown in Figure 35.
¶ All pending EMIF transactions are allowed to complete before HOLDA is asserted. If no bus transactions are occurring, then the minimum delay
time can be achieved. Also, bus hold can be indefinitely delayed by setting NOHOLD = 1.

PLL circuit. The PLL, however, may need up to 250 µs to stabilize following device power up or after PLL configuration has been changed. During

P = 1/CPU clock frequency in ns. For example, when running parts at 600 MHz, use P = 1.67 ns.
# This parameter is used during HPID reads and writes. For reads, at the beginning of a word transfer (HPI32) or the first half-word transfer (HPI16)
on the falling edge of HSTROBE, the HPI sends the request to the EDMA internal address generation hardware, and HRDY remains high until
the EDMA internal address generation hardware loads the requested data into HPID. For writes, HRDY goes high if the internal write buffer is
full.

These thermal resistance numbers were modeled using a heat sink, part number 374024B00035, manufactured by AAVID Thermalloy. AAVID
Thermalloy also manufactures a similar epoxy-mounted heat sink, part number 374024B00000. When operating at 720 MHz, a heat sink should
be used to reduce the thermal resistance characteristics of the package. TI recommends a passive, laminar heat sink, similar to the part numbers
mentioned above.

‡ These thermal resistance numbers were modeled using a heat sink, part number 374024B00035, manufactured by AAVID Thermalloy. AAVID
Thermalloy also manufactures a similar epoxy-mounted heat sink, part number 374024B00000. When operating at 720 MHz, a heat sink should
be used to reduce the thermal resistance characteristics of the package. TI recommends a passive, laminar heat sink, similar to the part numbers
mentioned above.

Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS
compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
