Abstract :
This multi-media enhanced, quad-issue, 550MHz RISC microprocessor includes hardware for MPEG-II encode/decode. It delivers 30 frame/s DVD playback with stereo-quality audio. Extensions to the instruction set for motion video estimation provide an order of magnitude improvement in computational capability, enabling video teleconferencing at 30 frame/s. An on-chip cache controller supports module caches using pipelined burst SRAMs to deliver up to 3.2GB/s data. The chip supports built-in-self-test (BIST) and repair of on-chip caches to reduce test cost.
