Abstract

PURPOSE:To simplify the page data transfer control between storage units and to decrease a necessary hardware by connecting an extended storage unit to a central processing unit and attaining the same method to use to extend a main storage unit. CONSTITUTION:When a transfer request between an extended storage unit (ESU)54 and a main memory unit (MSU)52 occurs at a central processing unit (CPU)50, the CPU activates the ESU 55. An ESU control circuit 60 issues a page data transferring starting request to the ESU 54. From the ESU 54 to receive the request, the page transfer data are sent into the data queuing of a memory control unit (MCU) 54. An MSU request to write the page data to the MSU 52 is issued one after another from the CPU 50. Thus, the access request for the page data transfer in the program execution of the CPU 50 is completed.
