Abstract:
An apparatus for gating a load operation is presented. The apparatus comprises a memory resident data structure, wherein the memory resident data structure is a prediction table comprising a plurality of entries, wherein a matching entry corresponding to the load operation within the prediction table comprises a prediction regarding a dependence of the load operation on a prior aliasing store instruction, and wherein the matching entry comprises: (a) a tag field operable to identify the matching entry; (b) a distance field operable to indicate a distance of the load operation to the prior aliasing store instruction; and (c) a confidence field operable to indicate a prediction strength generated by the prediction table, wherein the prediction strength influences a gating of the load operation.
