VLIW PROCESSOR CODESIGN FOR VIDEO PROCESSING

A codesign approach for complex video compression systems is presented . The system is based on a flexible and programmable VLIW (Very Long I nstruction Word) architecture. The design approach can be subdivided i nto two phases: a quantitative analysis for deriving the main processo r structure and a cosynthesis for generating the processor hardware an d the compiler back-end. The analysis results of different video compr ession algorithms are summarized. This permits to adapt the processor to a set of related applications rather than to a particular task. A c ompiled instruction-set simulator for analyzing large data sets is pre sented. An HTML-based codesign framework is shown which documents and organizes the analysis data.
