Methods and systems for a device coupled to a computing device are provided. As an example, one method includes receiving a request for processing an address list control block (ALCB) by an ALCB offload engine of an adapter coupled to a computing device; determining by the ALCB offload engine if the ALCB is located at a cache managed by a cache controller of the ALCB engine; forwarding the ALCB to an address computation module that determines an address of a memory location of the computing device, where the ALCB stores the address of the memory location in an address list; generating a direct memory access (DMA) request to retrieve the ALCB from an adapter memory, when the ALCB is not located at the cache; and storing the ALCB at the cache, after the ALCB is received in response to the DMA request.
