Abstract

M-PIRE is a programmable MPEG-4 multimedia codec VLSI for mobile and stationary applications. It integrates a RISC core, two separate DSPs, a 64-bit dual-issue VLIW macroblock engine, and an autonomous I/O processor on a single chip to cope with the high flexibility and processing demands of the MPEG-4 standard. The first M-PIRE implementation will consume 90 mm² in 0.25 μ CMOS technology. It will support real-time video and audio processing of MPEG-4 simple profile or ITU H.26x standards; future designs of M-PIRE will add support for higher MPEG-4 profiles. This paper focuses on the architecture, instruction set, and performance of M-PIRE´s macroblock engine, which carries most of the workload in MPEG-4 video processing
