Abstract
PURPOSE: To simplify the constitution of hardware by storing indication information of a block unit where there is a data to which access should be done in a tag part corresponding to a TLB indexing result and then by attaining access directly to the block unit.
CONSTITUTION: In access to a memory, the contents of actual address register 4 are processed by ±α counter 5 and when its contents exceed the block unit information of block unit 2-i of buffer memory 2, counter 5 detects a cross mode. As a result, logical address register 8 generates TLB index information, indicating unit 2-i where data resides, through ±1 counter 9 to change contents of tag 3 through logical and actual address storage parts 10 and 12 for each entry of TLB, address comparator 12 and encoder 13 and access direct to a unit, where no cross mode is generated, among units 2-i made to correspond to TLB entries is attained by using one comparing register, so that the constitution of hardware will be simplified.
