Abstract
In one embodiment, a processor comprises a cache and a cache miss unit coupled to the cache. The cache miss unit is configured to initiate a cache fill of a cache line for the cache responsive to a first cache miss in the cache, wherein the first cache miss corresponds to a first thread of a plurality of threads in execution by the processor. Furthermore, the cache miss unit is configured to record an additional cache miss corresponding to a second thread of the plurality of threads, wherein the additional cache miss occurs in the cache prior to the cache fill completing for the cache line. The cache miss unit is configured to inhibit initiating an additional cache fill responsive to the additional cache miss.
