Abstract
PURPOSE: To prevent extension of an object area of standby for a page fault time by selecting a prescribed address when page cross is detected.
CONSTITUTION: 2n-number banks BNK are interleaved in a memory unit correspondingly to lower n-number bits of logical address LA. The actual address obtained by converting a newly updated logical address is selected for the address of a bank where page cross is detected, and the actual address of address register group RALS which has not been updated yet is selected for other banks, and all banks are accessed simultaneously in respect to continuous data of an arbitrary length. Then, 2n-number page address bit counters for operations [+(2n-]1), -0], [+(2n -2), -1]...[+1, -(2n-2)], [+0, -(2n-1)] are provided correspondingly to 2n-number banks to detect page cross for every bank.
