Abstract

See full text

An address translation unit for use in a computer system having a multi-virtual space comprises a full associative translation lookaside buffer (TLB) which includes, for each entry, an associative memory array which stores and compares addresses. The associative memory array is provided with a circuit which, when a specific value is set in a common area field, invalidates comparison in a space number field.
