Abstract
A method and apparatus are contemplated for increasing the number of available instructions in an instruction set architecture. The new instructions extend the number of general-purpose registers and include three or more operands. A combination of an escape code field, an opcode field, an operation configuration field and an operation size field determines a unique new instruction operation. A source operand extension field includes bits to be combined with other fields in order to extend the number of source operand values for general-purpose registers.
