Systems, methods, and apparatuses for tile matrix multiplication and accumulation

A method comprising:

• decoding an instruction having fields for an opcode, an identifier for a first source matrix operand, an identifier of a second source matrix operand, and an identifier for a source/destination matrix operand, wherein the matrices are multi-dimensional and the opcode is to indicate the decoded instruction is to cause execution circuitry to multiply the identified first source matrix operand by the identified second source matrix operand, add a result of the multiplication to the identified source/destination matrix operand, and store a result of the addition in the identified source/destination matrix operand;
• and
• executing the decoded instruction to multiply the identified first source matrix operand by the identified second source matrix operand, add a result of the multiplication to the identified source/destination matrix operand, and store a result of the addition in the identified source/destination matrix operand.

A non-transitory machine-readable medium storing an instruction which causes a processor to perform a method, the method comprising:

• decoding the instruction having fields for an opcode, an identifier for a first source matrix operand, an identifier of a second source matrix operand, and an identifier for a source/destination matrix operand, wherein the matrices are multi-dimensional and the opcode is to indicate the decoded instruction is to cause execution circuitry to multiply the identified first source matrix operand by the identified second source matrix operand, add a result of the multiplication to the identified source/destination matrix operand, and store a result of the addition in the identified source/destination matrix operand;
• and
• executing the decoded instruction to multiply the identified first source matrix operand by the identified second source matrix operand, add a result of the multiplication to the identified source/destination matrix operand, and store a result of the addition in the identified source/destination matrix operand.
