Abstract
An apparatus and method for performing a vector bit reversal and crossing. For example, one embodiment of a processor comprises: a first source vector register to store a first plurality of source bit groups, wherein a size for the bit groups is to be specified in an immediate of an instruction; a second source vector to store a second plurality of source bit groups; vector bit reversal and crossing logic to determine a bit group size from the immediate and to responsively reverse positions of contiguous bit groups within the first source vector register to generate a set of reversed bit groups, wherein the vector bit reversal and crossing logic is to additionally interleave the set of reversed bit groups with the second plurality of bit groups; and a destination vector register to store the reversed bit groups interleaved with the first plurality of bit groups.
