A layered I/O architecture in a multicomputer-type DSP system is described that achieves efficient load balancing and high-speed video data distribution/gathering for real-time video processing. The layered structure is based on global distribution using buses and local distribution serial links. In addition to multiple homogeneous processing elements, the concept of bus nodes with high data distribution rates is introduced. System performance is evaluated by computer simulation focusing on load balancing efficiency using a typical video processing algorithm. It is shown that load balancing, which combines task assignment control with large-grain data flow, can provide high performance.
