Abstract

PURPOSE: To make efficient a transfer request for a memory unit by eliminating the latency when requests from request modules converge, by selecting at random and independently operating memory blocks by access ports.
CONSTITUTION: Access requests from transfer-request modules are inputted to access port input parts 301W304 and various informations such as addresses, data and control signals are inputted to memory blocks 101W106. Further, port assignment information from control part 501 is applied to access port assignment registers 201W216. Then, registers 201W206 determine the priority when requests from input parts 301W304 converge on one of memory blocks 101W116 and one of input parts 301W304 is selected for inputting the information, thereby performing the processing. Further, outputs of memory blocks 101W116 are sent to access port output parts 401W404 that correspond to input parts 301W304, so that transfer requests to the memory unit may be made efficient.
