  • Non-linear analog mapper for MEMS based optical circuit switches
    Patent number: 9366823
    Abstract: This disclosure provides systems, methods, and apparatus for a MEMS mirrors based optical circuit switch. The optical circuit switch includes digital to analog converter (DAC) for converting digital position codes into analog mirror position signals. A mapper transforms the analog mirror position signal into a mapped mirror position signal. The mapped mirror position signal is provided to a MEMS actuator that positions the MEMS mirror based on the mapped mirror position signal. The mapper transforms the analog mirror position signal into the mapped mirror position signal such that the MEMS mirror position has a substantially linear relationship with the analog mirror position signal provided by the DAC.

  • Register tracking for speculative prefetching
    Publication number: 20070118696
    Abstract: An apparatus and method for prefetching based on register tracking is disclosed. In one embodiment, an apparatus includes a register tracker and a pre-computation engine. The register tracker is to generate a pre-computation slice. The pre-computation engine is to execute the pre-computation slice.
