Abstract
A method of managing a direct-mapped cache is provided. The method includes a direct-mapped cache receiving memory references indexed to a particular cache line, using a first cache line replacement algorithm to select a main memory block as a candidate for storage in the cache line in response to each memory reference, and using a second cache line replacement algorithm to select a main memory block as a candidate for storage in the cache line in response to each memory reference. The method further includes identifying, over a plurality of most recently received memory references, which one of the algorithms has selected a main memory block that matches a next memory reference a greater number of times, and storing a block of main memory in the cache line, wherein the block of main memory stored in the cache line is the main memory block selected by the identified algorithm.
