Abstract
A method for manipulating packed data in a computer system. The method includes the steps of decoding a Single Instruction Multiple Data (SIMD) pack instruction. The instruction identifies a first and second packed data respectively including a first plurality of data elements and a second plurality of data elements. Each data element consists of a separate multiple bit data field, wherein each data element in the first plurality of data elements corresponds to a data element in the second plurality of data elements in a respective position. The method further includes the step of simultaneously copying, in response to the pack instruction, a part of each data element in the first plurality of data elements and a part of each corresponding data element in the second plurality of data elements into a third packed data as a plurality of separate result data elements.
