ABSTRACT:
An interface circuit and method are described, in which the interface circuit includes a plurality of bi-directional buffers and logic, responsive to a read request from a system component, configured to identify whether the requested data presently resides in the plurality of bi-directional buffers and is destined to be written from the bi-directional buffers to an external memory, wherein the logic is further configured to supply that data from the bi-directional buffers to the requesting system component, without first writing that data to the external memory.
