In an embodiment, when a device generates a pre-fetch request for a piece of data or an instruction from a memory hierarchy, the device includes a pre-fetch identifier in the request. This identifier flags the request as a pre-fetch request rather than a non-pre-fetch request, such as a time-critical request. Based on this identifier, the memory hierarchy can then issue an abort response at times of high traffic which suppresses the pre-fetch traffic, as the pre-fetch traffic is not fulfilled by the memory hierarchy. On receipt of an abort response, the device deletes at least a part of any record of the pre-fetch request and if the data/instruction is later required, a new request is issued at a higher priority than the original pre-fetch request."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Control of pre-fetch traffic","description":"Methods and systems for improved control of traffic generated by a processor are described.
