    摘要: The present invention discloses a method and apparatus for encoding an instruction in an instruction set which uses a prefix code to qualify an existing opcode of an existing instruction. An opcode and an escape code are selected. The escape code is selected such that it is different from the prefix code and the existing opcode. The opcode, the escape code, and the prefix code are combined to generate an instruction code which uniquely represents the operation performed by the instruction.

    摘要: An apparatus and method for performing a shuffle operation on packed data using computer-implemented steps is described. In one embodiment, a first packed data operand having at least two data elements is accessed. A second packed data operand having at least two data elements is accessed. One of the data elements in the first packed data operand is shuffled into a lower destination field of a destination register, and one of the data elements in the second packed data operand is shuffled into an upper destination field of the destination register.
