Claim:
1. A method of controlling traffic generated by a processor, the method comprising: attaching, at the processor, a pre-fetch identifier to a pre-fetch request to flag the pre-fetch request as a pre-fetch request, rather than a non-pre-fetch request, the pre-fetch request requesting an item from a memory hierarchy, wherein the item comprises a piece of data or an instruction; transmitting the pre-fetch request from the processor to the memory hierarchy; and in response to receiving, at the processor, an abort response corresponding to the pre-fetch request, removing at least a portion of data stored locally to the processor relating to the pre-fetch request, wherein the abort response is received at the processor from the memory hierarchy and the abort response is generated by a node of the memory hierarchy based on the pre-fetch identifier.
