Abstract
An apparatus and method for performing multiply-accumulate (MAC) operations on complex numbers to generate real results. For example, one embodiment of a processor comprises: a decoder to decode instructions including multiply-accumulate instructions; first and second source registers to store a first plurality of complex values and a second plurality of complex values, respectively, each complex value comprising a real value and an imaginary value; multiply-accumulate (MAC) execution circuitry coupled to the first and second source registers comprising multiplier circuitry, adder circuitry, and accumulator circuitry; mode selection circuitry to select between at least two execution modes for the MAC execution circuitry including a first mode in which the MAC execution circuitry is to perform complex multiply-accumulate operations using real and imaginary values from the first plurality of complex values and the second plurality of complex values and a second mode in which the MAC execution circuitry is to replace one or more of the real or imaginary values from the first and second plurality of complex values with one or more real or imaginary values specified in a set of scalar complex numbers or with zeroes.
