Abstract
In this paper, by implementing a realistic MPEG-4 core profile decoder over the TriMedia™ DSP chip, we investigate a serious of important issues related to the use of a media-processor to satisfy multimedia compression and processing requirement. The realistic MPEG-4 decoder optimized implementation by this DSP chip can support resolutions up to 4CIF (720 × 576) at 30 fps. The issues we investigated include the overview of characteristics of media-processor architecture, the speedup of the MPEG-4 decoder based on the TriMedia™ DSP chip, multimedia co-processor or hardware accelerator based approaches, Very Long Instruction Word (VLIW) and Single Instruction Multiple data (SIMD) programming technique and the media-processor based solution for set-top box applications.
