Abstract
A method, computer readable medium, and system are disclosed for decoupling data pre-fetch from demand loads. The method includes the steps of receiving, by a processor, a set of instructions that includes a load instruction; and executing, by the processor, the load instruction to perform a load operation. The load operation loads data from a cache unit into a register file. The load instruction includes a no-update operator that prevents the cache unit from updating the cache state information in response to the load operation. The result is that the eviction policy for the cache unit responds to the order of pre-fetch memory access requests rather than the demand load operations.
