1. A computer program product for executing a machine instruction in a central processing unit, the computer program product comprising:
a computer readable storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method comprising:
obtaining, by a processor, a machine instruction for execution, the machine instruction being defined for computer execution according to a computer architecture, the machine instruction comprising:
at least one opcode field to provide an opcode, the opcode identifying a Vector Galois Field Multiply Sum and Accumulate operation;a first register field to be used to designate a first register, the first register comprising a first operand;a second register field to be used to designate a second register, the second register comprising a second operand;a third register field to be used to designate a third register, the third register comprising a third operand;a fourth register field to be used to designate a fourth register, the fourth register comprising a fourth operand; andexecuting the machine instruction, the executing comprising:
multiplying one or more elements of the second operand with one or more elements of the third operand using carryless multiplication to obtain a plurality of products;performing a first mathematical operation on the plurality of products to obtain a first result;performing a second mathematical operation on the first result and one or more selected elements of the fourth operand to obtain a second result; andplacing the second result in the first operand. |
