Toshiba Corp. has announced the availability of the TC35280XB video codec LSI that encodes and decodes MPEG-4 A/V in mobile system for digital broadcasting and videophones.

Manufactured using a 0.135m process, the LSI integrates four dedicated RISC processors, tow of which encode and decode A/V data, while the others multiplex A/V streams and filter the noise.

The 11-by-11mm BGA device also embeds 16Mb of DRAM and consumes 180mW when processing MPEG-4 data at 125MHz. Pipeline architecture processes data in parallel and a clock-gating function (low power management) switches off the clock of non-activated blocks. Also integrated is dedicated circuitry for interfacing the DRAM, CMOS image sensor, and LCD.

The TC35280XB can encode and decode QCIF (176x144) data at 15 frames per second when used as a videophone at 60MHz, while simultaneously executing AMR speech codec and H.223 audio and video multiplexing. When used as an MPEG-4 viewer or recorder, CIF data is encoded or decoded at 15 frames per second at 125MHz.

Samples of TC35280XB will be available in Q4 and are priced at about $33.33 each.
