PROBLEM TO BE SOLVED: To cancel LSI pin neck and the connector neck of a package when a plurality of processors are connected to an external memory. SOLUTION: A storage controller 195 consists of: a plurality of selector groups 190; shared memories 160a, 160b connected by an inter-shared memory path 165; and cache memories 170a, 170b. Each 190 has four MP (Mathematical Programming) sections, two SM (System Management) selectors 140, and two CM (Communication Manager) selectors 150. Each MP section 110 has the processor, an LM (Local Memory) 114, an SM access circuit 113, a CM access circuit 112, and a buffer 115. The number of paths to the shared memories 160a, 160b from each SM selector is lower than the number of paths to each SM selector from the plurality of MP sections. The number of paths to the cache memories 170a, 170b from each CM selector is lower than the number of paths to each CM section from the plurality of MP sections. COPYRIGHT: (C)2004,JPO&NCIPI
