摘要

M-PIRE是用于移动和固定应用的可编程MPEG-4多媒体编解码器VLSI。它在单个芯片上集成了一个RISC核心、两个独立的dsp、一个64位双发行VLIW宏块引擎和一个自主I/O处理器，以应对MPEG-4标准的高灵活性和处理需求。第一个M-PIRE实现将在0.25 /spl mu/ CMOS技术中消耗90 mm/sup / 2。它将支持MPEG-4简单配置或ITU H.26x标准的实时视频和音频处理;M-PIRE的未来设计将增加对更高的MPEG-4配置文件的支持。M-PIRE的宏块引擎承担了MPEG-4视频处理的大部分工作，本文重点研究了该引擎的体系结构、指令集和性能。

The M-PIRE MPEG-4 codec DSP and its macroblock engine

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 mm/sup 2/ in 0.25 /spl mu/ 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.
