Abstract
The present invention comprises a multi-function shifter that uses N-nary logic and includes an operation selection and various 1-of-N multiplexers to support a variety of shift modes. The shift modes include rotates, logical shifts in which 0 is shifted into any vacated bit positions, and arithmetic shifts in which the value of the original most significant bit is shifted into any vacated bit positions. The present invention includes a general 32-bit shifter that can shift an arbitrary number of places in a single cycle, using any of the modes described above.
