Abstract

PURPOSE:To shorten the latency time till the access completion, by executing the access to plural addresses from the address nearest to the current address of a storage device. CONSTITUTION:When an address pointer 4 indicates an address A3 and data is requested to addresses A10, A3, A4, and A7 in order from an information processing device 3, these addresses are stored in address registers 6, and a control part 5 compares addresses with the address indicated by the address pointer 4. The address A4 for which the latency time is shortest is sent to a driver part 8, and data in this address is read out from a storage device 9 and is stored in a data register 7 corresponding to the address register 6 where the address A4 is stored. Simultaneously, the register 6 is made empty, and the access end is reported from the control part 5 to the device 3, and data sent from the register 7 is taken into the device 3.
