<p>PURPOSE:To provide a multiprocessor system with high processing speed which is composed of a host processor and a co-processor, etc., operated in accordance with the command of the host processor. CONSTITUTION:This multiporocessor system is provided with a first memory (a host memory 13, etc.) to be accessed by only a first processor (a host processor 11, etc.), a second memory (a local memory 14, etc.) to be accessed by the both of the first processor 11 and a second processor (a co-processor 12, etc.), a first bus (a host bus 15, etc.) to be connected with the first and second processors 11 and 12 and the first memory 13, a second bus (a local bus 16, etc.) to be connected with the second processor 12 and a bus selection circuit 17 selectively connecting either one of the first and second buses 15 and 16 with the second memory 14.</p> |
