Abstract

A technology for flushing a translation lookaside buffer (TLB) according to a designated key identification code (designated key ID). An instruction of an instruction set architecture is proposed to flush the TLB according to the designated key ID. A decoder transforms the instruction into at least one microinstruction. According to a flushing microinstruction included in the at least one microinstruction, a designated key ID is supplied to a control logic circuit of the TLB through a memory order buffer, so that the control logic circuit flushes matched entries in the TLB, wherein the matched entries match the designated key ID.
