The new DM642 is the first DSP of the DigitalMedia family that is based on the powerful C64 core. Dedicated to audio and video markets, it integrates glue-less interface to video decoders and encoders and audio codec.

This new SoC (Sytem on Chip) reduces video systems costs while allowing reaching unequalled performance and flexibility levels.

The DMEK/DMDK642 boards take advantage of DM642 and offer enhanced features like: Real Time Clock, IDE interface (hard disk, CDROM, DVDROM drive management), complete UART on RS232 or RS422 interface, Ethernet and HPI. These boards were originally designed for a stand-alone use but PC104 interface is available on request.

The kit is available in two versions :

• DMEK642 – Evaluation Kit: for DM642 and algorithms evaluation purpose

• DMDK642 – Development Kit: complete reference design for development and prototyping with FPGA and high speed daughter board port.

This new kit supports Ateme’s complete software offer for audio and video compression.
