Methods and apparatus for managing clock skew between clock domain boundaries

Abstract

Methods and apparatus provide for: a plurality of stages of combinational logic, each stage including a full latch circuit operable to transfer data into the given stage of combinational logic and a transparent latch circuit operable transfer output data from the given stage of combinational logic to a next of the stages; in each stage, passing state changes of output data from the given combinational logic irrespective of when such changes occur when a clock signal of the transparent latch circuit is at a first of two logic levels; and in each stage, withholding state changes of the output data until the clock signal of the transparent latch circuit transitions from the second of the two logic levels to the first logic level.
