摘要: In an embodiment, a processor includes at least one core having one or more execution units, a first cache memory and a first cache control logic. The first cache control logic may be configured to generate a first prefetch request to prefetch first data, where this request is to be aborted if the first data is not present in a second cache memory coupled to the first cache memory. Other embodiments are described and claimed.
