Cache management policies such as replacement, bypass, or shared cache partitioning have been relying on data reuse behavior to predict the future. This paper proposes a new way to use dynamic reuse distances to further improve such policies. A new replacement policy is proposed which prevents replacing a cache line until a certain number of accesses to its cache set, called a Protecting Distance (PD). The policy protects a cache line long enough for it to be reused, but not beyond that to… CONTINUE READING
