Title: Distributed shared memory multiprocessor system based on a unidirectional ring bus using a snooping scheme

Abstract: A distributed shared memory multiprocessor system based on a unidirectional ring bus using a snooping scheme comprises a group of processor nodes and a ring bus. The processor nodes are arranged in the form of a ring and one of the processor nodes generates a request signal for a data block, the remaining processor nodes snoop their own internal parts, and one of the remaining processor nodes provides the data block. The ring bus is used for connecting the processor nodes in the form of the ring and providing a path through which the request signal is broadcast to each of the remaining processor nodes and the data block is unicast to the processor node which has generated the request signal for the data block.
