ABSTRACT:
A method and apparatus for efficiently caching streaming and non-streaming data is described herein. Software, such as a compiler, identifies last use streaming instructions/operations that are the last instruction/operation to access streaming data for a number of instructions or an amount of time. As a result of performing an access to a cache line for a last use instruction/operation, the cache line is updated to a streaming data no longer needed (SDN) state. When control logic is to determine a cache line to be replaced, a modified Least Recently Used (LRU) algorithm is biased to select SDN state lines first to replace no longer needed streaming data.
