ABSTRACT:
A virtual space is divided into a plurality of areas of different memory block size, and a plurality of address translation modes are executed using different memory block sizes and based upon a virtual memory address. By dividing a part of the virtual memory space into finer memory blocks, the efficiency of use of the memory space is improved, and existing programs can be easily applied. Selecting one of a plurality of address translation modes is performed using such means as part of a virtual address, and/or a flag.
