Systems and methods for performing instructions to transform matrices into row-interleaved format

A method to be performed by a processor, the method comprising:

• fetching, using fetch circuitry, an instruction with a format having fields to specify an opcode and locations of source and destination matrices, wherein the opcode indicates that the processor is to transform the specified source matrix into the specified destination matrix having a row-interleaved (RowInt) format;
• decoding, using decode circuitry, the fetched instruction;
• and
• responding, using execution circuitry, to the decoded instruction by transforming the specified source matrix into the specified RowInt-formatted destination matrix by interleaving J elements of each J-element sub-column of the specified source matrix in either row-major or column-major order into a K-wide submatrix of the specified destination matrix, the K-wide submatrix having K columns and enough rows to hold the J elements.

A non-transitory machine-readable medium containing instructions, when executed by a processor, to cause the processor to respond by:

• fetching, using fetch circuitry, an instruction with a format having fields to specify an opcode and locations of source and destination matrices, wherein the opcode indicates that the processor is to transform the specified source matrix into the specified destination matrix having a row-interleaved (RowInt) format;
• decoding, using decode circuitry, the fetched instruction;
• and
• responding, using execution circuitry, the decoded instruction by transforming the specified source matrix into the specified RowInt-formatted destination matrix by interleaving J elements of each J-element sub-column of the specified source matrix in either row-major or column-major order into a K-wide submatrix of the specified destination matrix, the K-wide submatrix having K columns and enough rows to hold the J elements.
