The system is configured to push a first cache block that is hit by the first address in the first cache to a target location within the cache hierarchy or the main memory system, wherein the target location is unspecified in a definition of the first instruction within an instruction set architecture implemented by the first processor, and wherein the target location is implementation-dependent.
