  • Register-based shifts for a unidirectional rotator
    Patent number: 8335810
    Abstract: A processor having a unidirectional rotator configured to shift or rotate data in one direction is disclosed. The processor also includes a control unit having logic configured to modify a shift value specified by a registered-based shift, or rotate, instruction in an opposite direction, the modified shift value being usable by the rotator to shift, or rotate, the data in the one direction, and thereby, generate the same result as if the data in the rotator had otherwise been shifted, or rotated, in the opposite direction by the shift value originally specified by the registered-based instruction. The control unit is further configured to bypass the logic and provide to the rotator a shift value specified by a register-based instruction to shift, or rotate, the data in the one direction.

  • Circuits and methods employing a local power block for leakage reduction
    Patent number: 8314643
    Abstract: A circuit having a local power block for leakage reduction is disclosed. The circuit has a first portion and a second portion. The first portion is configured to operate at a substantially greater operating frequency than the operating frequency of the second portion. The second portion has a local power block configured to decouple the second portion if the second portion is inactive to reduce leakage current associated with the second portion without sacrificing performance of the first portion.
