Abstract
A signal processing system that includes a ring bus; a multiplicity of system modules, each coupled to the ring bus and operative to receive and transfer blocks of data words over the ring bus; and a bus control module coupled to the ring bus and operative to support simultaneous data transfers between specified pairs of system modules in accordance with concurrent execution of multiple programs of data transfer instructions. In an alternate embodiment, the signal processing system may include a plurality of ring buses wherein each system module is coupled to all of the ring buses and operative to receive and transfer blocks of data words over any one of the ring buses. In addition, the bus control module is also coupled to all of the ring buses and operative to support simultaneous data transfers between specified pairs of system modules over all of the ring buses. Moreover, each ring bus may comprise individual bus segments for system module to system module coupling about the ring.
