Invalidation of entries in a translation table by providing the machine a unique identification thereby disallowing a match and rendering the entries invalid

摘要: A virtual computer system having a translation lookaside buffer which converts address to real comprises register (VMNR) for storing the identification number (VMID) of currently running machine, bit holding VMID and comparison circuit compares held in with provided by VMNR predicates success conversion from on basis matching result comparison, management table data indicative VMIDs used define machines have run up current time point, control which, when an invalidation command is issued during selects unused as first information defining machine contents sets selected VMNR.
