Abstract
PURPOSE: To effectively use the TLB group by using the TLB group in the buffer when the new segment head addressed are in agreement, through the storage of the TLB group mostly used every STO address to separate buffer.
CONSTITUTION: The TLB work is replaced by determining the order freqeuntly uaed every one set in O to n way with the LRU replacement array. TLBSAVE stores the TLB group mostly used in the space corresponding to the area when the space is changed. STO section compares COM the STO address representing the changed space with the memory of STO stack, and when they are in agreement it is registrated in the STO array as NEWSTO and TBL is read out from the corresponding TLBSAVE and restored. The information is writtern in the way O and LRU uses only the way O. In case of disagreement, registration is made to OLDSTO which is taken as the newest STO address, and the content of corresponding TLBSAVE and TLB work are made ineffective, and the address LA and RA are obtained by using DAT and it is registrated in corresponding TLB.
