Abstract
An apparatus is provided that includes cache circuitry that comprises a plurality of cache lines. The cache circuitry treats one or more of the cache lines as trace lines each having correlated addresses and each being tagged by a trigger address. Prefetch circuitry causes data at the correlated addresses stored in the trace lines to be prefetched.
