ABSTRACT:
A method and apparatus for including in a processor instructions for performing intra-add operations on packed data. In one embodiment, a processor is coupled to a memory. The memory has stored therein a first packed data. The processor performs operations on data elements in the first packed data to generate a plurality of data elements in a second packed data in response to receiving an instruction. At least two of the plurality of data elements in the second packed data store the result of an intra-add operation on data elements in the first packed data.
