Abstract

PURPOSE:To purge only the corresponding entry in a TLB, by comparing the specific information of a virtual computer with the contents of a domain register. CONSTITUTION:When a program is changed to vary the contents of a register 1 plus control registers 2-0 and 2-1, the contents of a domain register 1 is hashed 3 to form a virtual computer VM-ID. Then a comparison 6 is carried out between the new and old VM fixed areas. if a coincidence is obtained from this comparison, the new VM fixed area is defined as the old VM fixed area to carry out the normal STO renewing process. In case no coincidence is obtained, the new VM fixed area is defined as the old VM fixed area. Then a VM send-out flag 10 is turned on, and at the same time a VM send-out ID is transmitted. Thus a TLB purges the entry containing the VM send-out ID.
