Abstract
A set associative cache memory, comprising: an array of storage elements arranged as N ways; an allocation unit that allocates the storage elements of the array in response to memory accesses that miss in the cache memory; wherein each of the memory accesses has an associated memory access type (MAT) of a plurality of predetermined MATs, wherein the MAT is received by the cache memory; a mapping that, for each MAT of the plurality of predetermined MATs, associates the MAT with a subset of one or more ways of the N ways; wherein for each memory access of the memory accesses, the allocation unit allocates into a way of the subset of one or more ways that the mapping associates with the MAT of the memory access; and wherein the mapping is dynamically updatable during operation of the cache memory.
