Abstract

PURPOSE:To attain access of all physical memory areas of a storage device by providing a physical address conversion mechanism section converting an address into a physical address accessing the address space expanded more than the noticed real address. CONSTITUTION:The high-order physical address information being the result of entering the high-order address of a real address 2 into a physical address conversion device section 1 and the low-order physical address information corresponding to the low-order address of the real address are used to convert the address into the expanded physical address 3. Thus, as to all memory spaces of the storage device having an address bus number larger than the address bus number between the processing unit and the storage access controller, all the memory spaces are accessed without revising the remarkable change of the hardware.
