Method and apparatus for providing packed shift operations in a processor |
摘要 |
A method and apparatus for providing, in a processor, a shift operation on a packed data element having multiple values. The apparatus having multiple muxes, each of the multiple muxes having a first input, a second input, a select input and an output. Each of the multiple bits that represent a shifted packed intermediate result on a first bus is coupled to the corresponding first input. Each of the multiple bits representing a replacement bit for one of the multiple values is coupled to a corresponding second input. Each of the multiple bits driven by a correction circuit is coupled to a corresponding select input. Each output corresponds to a bit of a shifted packed result.
