  • Patent number: 7477713
    Abstract: Aspects of providing automatic adaptation to frequency offsets in high speed serial links are described. First signals for phase adjusts in a receiver link are adjusted by detecting trends in the first signals to generate second signals, the second signals improving a rate of compensation for the frequency offsets by the phase adjusts. An up/down counter is included for counting signals for phase adjustments by a clock-data-recovery loop of a serial receiver. An adder is coupled to the up/down counter and outputs accumulated data indicative of a trend in the phase adjustments. Combinatorial logic coupled to the adder adapts the signals based on the accumulated data.

  • Patent number: 7474123
    Abstract: Reducing power consumption in latches and similar electronic devices. In one aspect, an apparatus for configuring power consumption of sequential logic includes a sequential logic device including a first latch, a second latch, and first and second enable inputs. The first enable input enables and disables the first and second latches, and the second enable input enables and disables the second latch and does not affect the first latch. The first enable input has an earlier required signal arrival time than the second enable input to be effective for a particular clock cycle. A circuit configures the sequential logic device at operating time to consume less power during a lower frequency of operation of the sequential logic device, and to consume more power during a higher frequency of operation.
