SYSTEMS AND METHOD FOR UNBLOCKING A PIPELINE WITH SPONTANEOUS LOAD DEFERRAL AND CONVERSION TO PREFETCH

摘要

Apparatuses, systems, and a method for providing a processor architecture with a control speculative load are described. In one embodiment, a computer-implemented method includes determining whether a speculative load instruction encounters a long latency condition, spontaneously deferring the speculative load instruction if the speculative load instruction encounters the long latency condition, and initiating a prefetch of a translation or of data that requires long latency access when the speculative load instruction encounters the long latency condition. The method further includes reaching a check instruction, which resteers to recovery code that executes a non-speculative version of the load.
