TLB MANAGEMENT METHOD AND APPARATUS

摘要

A TLB (Translation Look-aside Buffer) management method and apparatus relate to the technical field of computers and can reduce TLB miss rate. The method comprises: querying a TLB storage directory table by taking the VPIDs (Virtual-Processor Identifier) of VCPUs (Virtual Central Processing Unit) as index, to obtain the address of a TLB storage table corresponding to a first VCPU in a memory area; then accessing the TLB storage table corresponding to the first VCPU according to the address of the TLB storage table corresponding to the first VCPU in the memory area, and reading valid TLB table entries in the TLB storage table corresponding to the first VCPU into physical TLB in turns, wherein the TLB table entries as well as validity identifiers corresponding to the various TLB table entries are stored in the TLB storage table, and the validity identifiers are used for representing whether the TLB table entries are valid or not.
