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

International audienceReal time signal, image and control applications have very important time constraints, involving the use of several powerful numerical calculation units. The aim of our project 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 CAD software developed to improve algorithm implementation onto multiprocessor architectures, finding the best matching between an algorithm and an architecture. We have developed a SynDEx executive kernel for the C6X DSP family, in order to automatically generate a distributed and optimised static executive of the specified algorithm onto those processors. We have tested the efficiency of our methodology with a complete Mpeg-2 coding application
