Abstract
An apparatus and method for complex matrix transpose and multiply. For example, one embodiment of a processor comprises: a decoder to decode a first complex matrix multiplication and transpose instruction including a first source operand to identify a first plurality of real and imaginary values in a first complex source matrix, a second source operand to identify a second plurality of real and imaginary values in a second complex source matrix, and a first destination operand to identify a result matrix with real and imaginary values; execution circuitry to execute the first complex matrix transpose and multiplication instruction, the execution circuitry comprising transpose hardware logic to transpose at least one of the source matrices, 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…
