摘要: An apparatus and method for performing an intra-add operation on packed data using computer-implemented steps is described. A processor is coupled to a hardware unit which transmits data representing graphics to another computer or display. A storage device coupled to the processor, has stored therein a routine, which, when executed by the processor, causes the processor to generate the data. The routine causes the processor to at least access a first packed data operand having at least one pair of data elements; swap positions of the data elements within the at least one pair of data elements to generate a second packed data operand, add data elements starting at the same bit positions from the first and second packed data operands to generate a third packed data operand.
