Abstract

A programmable processor architecture for MPEG-4 video is proposed, that can serve as a coprocessor module in MPEG-4 decoder systems. It consists of a 64-bit dual-issue VLIW macroblock engine, a separate RISC core for bitstream parsing and system processing, and an autonomous I/O processor. A separate DSP is used for MPEG audio support. The architecture is fully programmable and supports parallelism on data-, instruction- and thread-level to cope with the high flexibility and processing demands of the MPEG-4 standard. The first implementation will support real-time decoding of MPEG-4 advanced simple profile or of MPEG-4 ACE-profile (CCIR601, single-object). Future designs will add support for object-based MPEG-4 functionalities. The paper focuses on the architecture, instruction set, and performance of the macroblock engine, which operates as an autonomous co-processor and carries most of the workload in MPEG-4 video processing. It has a RISC-based architecture with support for parallel processing of instructions and data. Special instructions are implemented with specific support for video processing.
