Conception et réalisation d'une machine parallèle de codage d'images à bas débit sur un réseau de transputers

Abstract : This thesis is a contribution to algorithms parallelization in signal processing and moreover in image processing. Through a precise example, it appears that image processing application is a privileged field for the study and implementation of parallelism. Many parallelism techniques have been tested on a low rate image coding algorithm. Our purpose was to achieve a low-cost Transputer system for image coding. The critical sofware parts have been replaced by specialized prototype cards. DCT (discrete cosine tranformation) and Q.V. (vector quantization) cards were developed, and then used in a parallel machine based on a network of transputers. This machine includes very interesting architectural concepts, some of wich were patented
