For example, a processor is described to execute an instruction to perform the operations of: reading a plurality of mask bits stored in a source mask register, the mask bits associated with vector data elements of a vector register; and performing a bit reversal operation to copy each mask bit from a source mask register to a destination mask register, wherein the bit reversal operation causes bits from the source mask register to be reversed within the destination mask register resulting in a symmetric, mirror image of the original bit arrangement."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and method to reserve and permute bits in a mask register","description":"An apparatus and method are described for performing a bit reversal and permutation on mask values.
