Abstract
A method and apparatus for communicating signals between a source synchronous component and a non-source synchronous component of a system is described. The present invention provides a strobe signal from the source synchronous component that is delayed and used to latch data received from a non-source synchronous component. The amount of delay provided is determined based on the timing of data request cycles to the non-source synchronous component. Thus, the present invention allows data to be received by a source synchronous component from a component that does not generate a strobe signal used for latching received data that would be generated by a source synchronous component.
