Abstract :
The authors present the implementation of a MPEG encoder on a multicomputer system developed by the University of California at Berkeley. The topology of the system is analyzed together with the most adequate commutation technique for the interconnection network. They also propose a mapping of the video sequence between the PEs of the architecture taking into account the necessary load process. Finally the effect of the frame format on the system communication performance is analyzed
