ABSTRACT:
The present invention provides a method, in a computer system, for compressing bit formats provided in a first packed data sequence. One embodiment of the method comprises the steps of generating, in response to execution of a first instruction, a second packed data sequence by copying the first packed data sequence. A second step of replacing, in response to execution of a second instruction, a first portion of the second packed data sequence with a second portion of the second packed data sequence. A third step of generating, in response to execution of a third instruction, an intermediate result, by multiplying data elements of the first packed data sequence with corresponding data elements of a third packed data sequence, and adding adjacent products. A fourth step of performing, in response to execution of a fourth instruction, a first shift operation, wherein bits of the second packed data sequence are shifted. A fifth step of generating, in response to execution of a fifth instruction, a final result by performing a bit wise logical OR operation between the second packed data sequence and the intermediate results.
