  • Method and apparatus for synchronously transferring data across multiple clock domains
    Patent number: 6744285
    Abstract: A method and an apparatus for aligning the phases of clocks of different clock domains of an IC to enable data to be transferred synchronously across the clock domains. The present invention comprises a phase-alignment system that is adjustable via a user interface to enable the clock phases to be adjusted. A user controls the degree of alignment of the phases via the user interface. The present invention enables the phases of clocks of different clock domains to be adjusted even after the IC has been fabricated.
