Abstract
In order to carry out address translation which can reduce an overhead of the VMCP to support a virtual storage, a flag indicating a common segment in the virtual machine and a system identifier are held in a TLB, and a VM identifier is held in a segment table origin stack. For the common segment, a current VM identifier is compared with the VM identifier in the segment table origin stack to determine validity of a TLB entry, and for a non-common segment, a system identifier read from the segment table origin stack is compared with the system identifier in the TLB entry to determine validity of the TLB entry.
