Abstract

The compression and decompression of MPEG-2 video play a major role in entertainment delivery devices. This paper investigates software MPEG-2 video decoding on a multiprocessing microprocessor, MAJC-5200. MAJC (microprocessor architecture for Java computing), is a very long instruction word (VLIW) processor with an instruction set geared towards multimedia computing. We describe the microprocessor and show that less than 50% of a single CPU out of the available true processors is sufficient for decoding 4 Mb/s video sequences.
