Abstract
A processor for performing a vector permute comprises: a source vector register to store a plurality of source data elements; a destination vector register to store a plurality of destination data elements; a control vector register to store a plurality of control data elements, each control data element corresponding to one of the destination data elements and including an N bit value indicating whether a source data element is to be copied to the corresponding destination data element; vector permute logic to compare the N bit value of each control data element to an N bit portion of an immediate to determine whether to copy a source data element to the corresponding destination data element, wherein if the N bit values match, then the vector permute logic is to identify a source data element using an index value included in the control data element.
