摘要：
A method and apparatus is disclosed for manipulating vectored data. The method includes shifting bits of packed data comprising M N-bit elements using a bit-level shift step followed by a byte-level shift step. A mask is generated and applied to the intermediate shifted result to produce the final result. A method is disclosed for conditionally transferring data from one general purpose register to another based on data in yet a third general purpose register.
