Patent number: 6321284Abstract: A data processing system having one or more processor modules and a plurality of shared memory busses to increase its total system performance. Processor modules send bus requests to a bus arbiter, when they attempt to make access to shared memories or memory-mapped peripheral control modules. When such memory access requests are received, the bus arbiter checks the availability of each bus that will be used to reach the requested memories, and send bus grant signals to the requesting processor modules after resolving conflicts, if any. Since the system provides separate paths to reach the individual shared memories, two or more processor modules can be granted their access requests at the same time.Type: GrantFiled: March 12, 1999Date of Patent: November 20, 2001Assignee: Fujitsu LimitedInventors: Akio Shinohara, Hideo Abe, Katsuichi Ohara
