ABSTRACT:
A method and an apparatus for profile guided TLB's (translation look-aside buffer) and cache optimization in an operating system. A typical operating system has a working set of information for any application which is running at some time. This working set of information can be written out by the operating system in some section of the object file. Once this information is in the object file, it may be utilized by the operating system in various ways. The method and apparatus decreases TLB misses for the benchmarks, disables infrequently used pages from disturbing the caches, and provides better rates on caches. This and many other advantages of the invention allow an increased efficiency and optimization of a given operating system.
