Rapid Prototyping Methodology For multi-DSP Tl C6X Platforms Applied to an Mpeg-2 Coding Application

摘要

Real time signal and image applications have very important time constraints, involving the use of several powerful numerical calculation units. Our aim is to develop a fast prototyping process dedicated to parallel architectures made of several last generation Texas Instruments TMS320C6X DSP. The methodology is based on the use of SynDEx, a GAD software improving the algorithm implementation onto multiprocessor architectures, finding the best matching between an algorithm and an architecture. A SynDEx executive kernel has been developed for the C6X DSP family in order to automatically generate a distributed and optimized static executive of the specified algorithm onto those processors. We have tested the efficiency of our methodology with a complete Mpeg-2 coding application.
