Abstract
There is provided an apparatus, a system, a chip containing product, a method, and a computer-readable medium. The apparatus comprises pattern storage circuitry to store information indicative of a plurality of prefetch patterns, each prefetch pattern indicating a trigger access request and comprising pattern information associated with the trigger access request. The pattern information is indicative of one or more addresses to be used for generation of prefetch requests. The apparatus also comprises control circuitry responsive to an observation of the trigger access request indicated in a prefetch pattern to determine whether the prefetch pattern is selected for training by prefetch training circuitry. Each of the plurality of prefetch patterns comprises back-off information indicating a back-off period during which the prefetch pattern is to be overlooked for the training. The control circuitry is responsive to the prefetch pattern being selected for the training to update the back-off information.
