Abstract
PURPOSE:To start the writing and reading operations of storage circuits simultaneously, and to process simultaneous requests to a different storage device instantaneously, by providing selecting circuits for input information and readout data corresponding to a storage circuit and an external circuit. CONSTITUTION:Through N units of input information selecting circuits WAS, M pieces of input information from M CPUs are selected with corresponding input information selection signals S and, when corresponding hold indication signals AD are supplied, held in N bank information registers WARs. Then, when a corresponding start signal E is supplied, write data in the input information held in the corresponding register WAR is written N storage circuits M' in write mode and readout data is outputted in readout mode. Then, N readout data from the storage circuits M' are selected by M readout data selecting circuit RS with corresponding readout data selection signals AR and then outputted to the M CPUs, so that simultaneous requests to different storage devices are processed instantaneously.
