About This Manual

This document describes the video port and VCXO interpolated control (VIC) port in the digital signal processors (DSPs).

Notational Conventions

This document uses the following conventions.

∙Hexadecimal numbers are shown with the suffix h. For example, the following number is 40 hexadecimal (decimal 64): 40h.

∙Registers in this document are shown in figures and described in tables.

–Each register figure shows a rectangle divided into fields that represent the fields of the register. Each field is labeled with its bit name, its beginning and ending bit numbers above, and its read/write properties below. A legend explains the notation used for the properties.

–Reserved bits in a register figure designate a bit that is used for future device expansion.

SPRS372 — TMS320DM647/DM648 Digital Media Processor Data Manual describes the signals, specifications and electrical characteristics of the device.

SPRU732 — 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.

SPRUEK5 — 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.

SPRUEK6 — TMS320DM647/DM648 DSP External Memory Interface (EMIF) User's Guide describes the operation of the asynchronous external memory interface (EMIF) in the TMS320DM647/DM648 Digital Signal Processor (DSP). The EMIF supports a glueless interface to a variety of external devices.

SPRUEK7 — TMS320DM647/DM648 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.
