摘要
Techniques for increasing vector processing utilization and efficiency through use of unmasked lanes of predicated vector instructions for executing non-conflicting instructions are provided. In one aspect, a method of vector lane predication for a processor is provided which includes the steps of: fetching predicated vector instructions from a memory; decoding the predicated vector instructions; determining if a mask value of the predicated vector instructions is available and, if the mask value of the predicated vector instructions is not available, predicting the mask value of the predicated vector instructions; and dispatching the predicated vector instructions to only masked vector lanes.
