  • Systems and methods for driving data over a bus where the systems employ a bus clock that is derived from a system clock and a data clock designed to lead the bus clock
    Patent number: 7464284
    Abstract: Systems and methods for driving data over a data bus are disclosed. One embodiment of a system may comprise a bus clock signal that is a copy of a system clock signal that controls the timing associated with transferring data over the bus, a data clock signal that is designed to lead the system clock by a portion of a clock cycle to drive data over the bus ahead of the bus clock signal, an output latch device that drives data over the data bus in response to an edge of the data clock signal and a skew corrector that mitigates racing of data over the data bus in the event that the data clock lags the bus clock.
