Abstract

CPU cache performance can be improved by appropriate use of cache manipulation instructions to inform the cache of information about areas of memory that the program would like to access in the near future. Addition of another simple instruction could improve cache performance further by giving the program the ability to inform the cache of areas of memory that it is has recently accessed, but it unlikely to access again.
