Abstract

PURPOSE: To reduce the capacity of the address conversion buffer of an information processing system, by giving effect to registration by changing the size of a segment.
CONSTITUTION: Once virtual address 100 is set in virtual address unit 200, address conversion buffer 103 is referred to by the entirety or part of segment number 100a. When there is not an address conversion couple to be found in buffer 103, address boundary selecting method 202 selects an address conversion couple from address boundary unit 201. Segment size 10lb read out from a main memory unit is set in unit 201 and then compared 203 with address 100b in a segment in unit 200. In case of a large segment, when there are an address size 101b assigns and that address 100b assigns in the same 64k byte boundary area, sixteen low-order bits of size 101b are registered in size part 103c of buffer 103.
