Abstract
Embodiments of the invention relate to a method and system to implement a DDR interface, such as a high-speed encode/decode interface. In one embodiment, a method of encoding data comprises the acts of (1) receiving a first signal, a second signal, and a first clock signal common to the first and second signals; (2) detecting rising edges and falling edges of the first clock signal; and (3) generating a composite signal based at least in part on the first and second signals and the detected rising and falling edges. The composite signal is associated with a second clock signal that is generated based at least in part on the detected rising and falling edges and on a time delay relative to the first clock signal.
