DEVICE AND METHOD FOR PROCESSING FRACTIONAL REVOLUTIONARY OPERATIONS

摘要

An apparatus and method for performing a reversal. For example, one embodiment of a processor includes: a decoder to decode a reverse command to generate a decoded reverse command; a source register for storing at least one packed input data item; a destination register for storing a result data item; and a reciprocal execution interconnect for executing the decoded invert instruction, the reciprocal execution interconnection having a first portion of the packed input data item to use as an index for a data structure containing a plurality of sets of coefficients to obtain a first set of coefficients from the plurality of coefficients Identify sentences, wherein the reciprocal execution interconnection using a combination of the coefficients and a second portion of the packed input data item to generate an inverse of the packed input data item.
