Abstract: An apparatus and method for complex matrix multiplication. For example, one embodiment of a processor comprises: a decoder to decode a first complex matrix multiplication instruction; execution circuitry to execute the first complex matrix multiplication instruction, the execution circuitry comprising parallel multiplication circuitry to multiply real values from the first plurality of real and imaginary values with corresponding real values from the second plurality of real and imaginary values to generate a first plurality of real products, to multiply imaginary values from the first plurality of real and imaginary values with corresponding imaginary values from the second plurality of real and imaginary values to generate a second plurality of real products; and addition/subtraction circuitry to subtract each real product in the second plurality of real products from a corresponding real product in the first plurality of real products to produce a corresponding real value in the result matrix. The decoder may also decode and the execution circuitry may execute a second complex matrix multiplication instruction to multiply real and imaginary values from the first plurality with corresponding imaginary and real values, respectively, from the second plurality to generate first and second pluralities of imaginary products, and to add corresponding imaginary products to produce a corresponding imaginary value in the result matrix.

Abstract: An apparatus and method for complex matrix conjugation. For example, one embodiment of a processor comprises: a decoder to decode a complex conjugate transpose instruction including a source operand to identify a complex source matrix and a destination operand to identify a complex result matrix, the complex source matrix to store a first plurality of complex values and the complex result matrix to store a second plurality of complex values, each complex value in the first and second plurality of complex values including a real component and an imaginary component; a plurality of registers or local memory to store all or a subset of the first plurality of complex values; and execution circuitry to execute the complex conjugate transpose instruction using matrix conjugation hardware logic to determine a plurality of complex conjugate values corresponding to the first plurality of complex values, and transpose hardware logic to perform a matrix transpose operation using the plurality of complex conjugate values to generate a result matrix.
