1. A processor comprising:
a decoder to decode a single complex matrix conjugation and multiplication instruction including a first source operand to identify a first complex source matrix comprising a first plurality of complex values including a corresponding first plurality of real values and a corresponding first plurality of imaginary values, a second source operand to identify a second complex source matrix comprising a second plurality of complex values including a corresponding second plurality of real values and a corresponding second plurality of imaginary values, a first destination operand to identify an imaginary result matrix, and an opcode to indicate a combined complex matrix conjugation and multiplication operation using the first plurality of complex values and the second plurality of complex values to generate the imaginary result matrix;
execution circuitry to execute the single complex matrix conjugation and multiplication instruction, the execution circuitry comprising:
matrix conjugation hardware logic comprising inversion circuitry to determine a plurality of complex conjugate values corresponding to the first plurality of complex values by inverting sign values of the corresponding first plurality of imaginary values to generate a corresponding plurality of sign-inverted imaginary values;
transpose hardware logic to transpose the plurality of complex conjugate values to generate a conjugate transpose matrix comprising the plurality of complex conjugate values including the corresponding plurality of sign-inverted imaginary values;
parallel multiplication circuitry to:
multiply real values from the plurality of complex conjugate values of the conjugate transpose matrix with corresponding imaginary values from the second plurality of complex values to generate a first plurality of imaginary products, and
multiply the sign-inverted imaginary values from the plurality of complex conjugate values of the conjugate transpose matrix with corresponding real values from the second plurality of complex values to generate a second plurality of imaginary products; and
addition/subtraction circuitry to add each imaginary product in the first plurality of imaginary products to a corresponding imaginary product in the second plurality of imaginary products to produce a corresponding imaginary value of the imaginary result matrix.
