TMS320DM642 Technical Overview

The TMS320DM642 Digital Media Processor is based on the C64x CPU, which is part of the C6000 DSP family. The DM642 integrates a number of peripherals to address the development of video and imaging applications, including three configurable video ports capable of glueless video input, video output, or transport stream input. These video ports can support BT.656 video I/O, HDTV Y/C I/O at upto 10-bits per component, RGB I/O, MPEG-2 Transport stream inputs. Also included on the DM642 is a 10/100 Mbps ethernet MAC (EMAC), a multichannel audio serial port (McASP) that supports common audio interface modes including I2S and DIT, a 66 MHz 32-bit PCI bus, and a number of other peripherals.

This document describes the DM642 architecture including details of its peripherals. Several example applications are described, showing how DM642 can be used in development of video IP phones, video-on-demand set-top boxes, and surveillance digital video recorders.
