  • Disparate clock domain synchronization
    Patent number: 8442075
    Abstract: Disparate clock domains are resynchronized after circuits in one of the clock domains awake from a reduced power state. Parallel test data is routed from a core circuit to a parallel-to-serial converter in an input/output (I/O) circuit. The parallel-to-serial converter clocks the parallel test data in response to a load signal. The load signal is varied until the clock domains are synchronized.
    Type: Grant

    Date of Patent: May 14, 2013
    Assignee: Intel Corporation

  • Clock domain crossing
    Publication number: 20070079167
    Abstract: Provided are a method, system, and device to effectuate a transfer of data from one clock domain to another. In accordance with one aspect of the description provided herein, bits of data to be transferred are shifted in the first clock domain. The shifted bits of data to be transferred may be sampled in a second clock domain at a fixed time within each clock signal of the first clock domain. A stream of sampled bits may be output in the second clock domain. Additional embodiments are described and claimed.
