Method for data processing of frame receiving of an interconnection protocol and storage device

A method for data processing of frame receiving of an interconnection protocol and a storage device, for use in a first device linkable to a second device according to the interconnection protocol. The method includes: in processing of frames originating from the second device and received by the first device: while sending data contained in a first frame to a network layer from a data link layer, pre-fetching symbols of a second frame; and after the data contained in the first frame are sent to the network layer and the symbols of the second frame are pre-fetched, sending data contained in the second frame to the network layer. Upon receipt of back-to-back frames, the efficiency of the frame receiving at the data link layer is enhanced.
