Abstract
Embodiments include methods, systems, and computer readable medium directed to cache bypassing based on prefetch streams. A first cache receives a memory access request. The request references data in the memory. The data comprises non-reuse data. After a determination of a miss in the first cache, the first cache forwards the memory access request to a cache control logic. The detection of the non-reuse data instructs the cache control logic to allocate a block only in a second cache and bypass allocating a block in the first cache. The first cache is closer to the memory than the second cache.
