摘要:
A method for compiler assisted victim cache bypassing including: identifying a cache line as a candidate for victim cache bypassing; conveying a bypassing-the-victim-cache information to a hardware; and checking a state of the cache line to determine a modified state of the cache line, wherein the cache line is identified for cache bypassing if the cache line that has no reuse within a loop or loop nest and there is no immediate loop reuse or there is a substantial across loop reuse distance so that it will be replaced from both main and victim cache before being reused.
