Abstract
This invention simulates program to create a conflict graph of the cache accesses. The conflict graph is used to relay out relocatable functions to minimize cache conflict misses where conflicting functions map to the same portion of the cache. The conflict graph includes a vertex for each function and an edge between functions having a weight corresponding to a conflict amount. This conflict graph enables a layout of functions to minimize the number of conflicting items that map to the same location in the cache weighted by the degree of conflict encoded by the edges in the graph.
