Silt: A distributed bit-parallel architecture for early vision

摘要

A new form of parallelism,distributed bit-parallelism, is introduced. A DBP organization distributes each bit of a data item to a different processor. DBP allows computation that is sublinear with word size for such operations as integer addition, arithmetic shifts, and data moves. The implications of DBP for system architecture are analyzed. An implementation of a DPB architecture based on a mesh with a fost-bypass network is presented, and the performance of DBP algorithms on this architecture is analyzed. The application of the architecture to early vision algorithms is discussed.
