METHOD FOR MANAGING TRANSLATION LOOKASIDE BUFFER AND MULTI-CORE PROCESSOR

摘要

A translation lookaside buffer TLB management method and a multi-core processor are provided. The method is applied to the multi-core processor, the multi-core processor includes a first core, the first core includes a TLB, and the method includes: receiving, by the first core, a first address translation request, and querying the TLB of the first core based on the first address translation request (210); determining that a first target TLB entry corresponding to the first address translation request is missing in the TLB of the first core, obtaining the first target TLB entry (220); when determining that entry storage in the TLB of the first core is full, determining a second core from cores in an idle state in the multi-core processor (230); and replacing a first entry in the TLB of the first core with the first target TLB entry, and storing the first entry in a TLB of the second core (240). According to this method, a TLB resource of a core in an idle state is used to expand a TLB capacity of a working core, thereby reducing a TLB miss rate and accelerating program execution.
