TMS320C64x/C64x+ DSP CPU and Instruction Set Reference Guide describes the CPU

architecture, pipeline, instruction set, and interrupts for the TMS320C64x and TMS320C64x+

digital signal processors (DSPs) of the TMS320C6000 DSP family. The C64x/C64x+ DSP

generation comprises fixed-point devices in the C6000 DSP platform. The C64x+ DSP is an

enhancement of the C64x DSP with added functionality and an expanded instruction set.

TMS320DM647/DM648 DSP DDR2 Memory Controller User's Guide describes the DDR2

memory controller in the TMS320DM647/DM648 Digital Signal Processor (DSP). The

DDR2/mDDR memory controller is used to interface with JESD79D-2A standard compliant

DDR2 SDRAM devices and standard Mobile DDR SDRAM devices.

DSP

General-Purpose

Input/Output

(GPIO)

User's

Guide

describes the general-purpose input/output (GPIO) peripheral in the TMS320DM647/DM648

Digital Signal Processor (DSP). The GPIO peripheral provides dedicated general-purpose

pins that can be configured as either inputs or outputs. When configured as an input, you

can detect the state of the input by reading the state of an internal register. When configured

as an output, you can write to an internal register to control the state driven on the output

pin.

SPRUEK8

TMS320DM647/DM648 DSP Inter-Integrated Circuit (I2C) Module User's Guide describes

the inter-integrated circuit (I2C) peripheral in the TMS320DM647/DM648 Digital Signal

Processor (DSP). The I2C peripheral provides an interface between the DSP and other

devices compliant with the I2C-bus specification and connected by way of an I2C-bus.

External components attached to this 2-wire serial bus can transmit and receive up to 8-bit

wide data to and from the DSP through the I2C peripheral. This document assumes the

reader is familiar with the I2C-bus specification.

SPRUEL0

TMS320DM647/DM648 DSP 64-Bit Timer User's Guide describes the operation of the 64-

bit timer in the TMS320DM647/DM648 Digital Signal Processor (DSP). The timer can be

configured as a general-purpose 64-bit timer or dual general-purpose 32-bit timers.

TMS320DM647/DM648 DSP Multichannel Audio Serial Port (McASP) User's Guide

describes the multichannel audio serial port (McASP) in the TMS320DM647/DM648 Digital

Signal Processor (DSP). The McASP functions as a general-purpose audio serial port

optimized for the needs of multichannel audio applications. The McASP is useful for time-

division

TMS320DM647/DM648 DSP Enhanced DMA (EDMA) Controller User's Guide describes

the operation of the enhanced direct memory access (EDMA3) controller in the

TMS320DM647/DM648 Digital Signal Processor (DSP). The EDMA3 controller’s primary

purpose is to service user-programmed data transfers between two memory-mapped slave

endpoints on the DSP.

SPRUEL4

TMS320DM647/DM648 DSP Peripheral Component Interconnect (PCI) User's Guide

describes the peripheral component interconnect (PCI) port in the TMS320DM647/DM648

Digital Signal Processor (DSP). The PCI port supports connection of the C642x DSP to a
