    摘要: A method and apparatus for including in a processor instructions for performing multiply-subtract operations on packed data. In one embodiment, a processor is coupled to a memory. The memory has stored therein a first packed data and a second packed data. The processor performs operations on data elements in said first packed data and said second packed data to generate a third packed data in response to receiving an instruction. At least one of the data elements in this third packed data storing the result of performing a multiply-subtract operation on data elements in the first and second packed data.
