Abstract: A method for finding an MSD(Minimal Signed Digit) with variable multi-bit coding is provided to implement an additional operation easily for calculating a value of a signed digit occurring as bits get bigger, and minimize an area/time needed for implementing a program and making hardware by finding the signed digit with grouped numbers. Each group is checked when a predetermined multi-bit applying a Booths algorithm is scanned and grouped(S302). A positive or negative coding mode is determined depending on a type of each group(S303). Grouping is terminated when the grouped MSB(Most Significant Bit) is not identical with a value of a previous bit if the type of the group is not found. A signed number is found by converting and using a value of each group based on a predetermined mode when the coding mode is the positive coding mode(S304). Bitwise inversion for the value of each group is performed when the coding mode is the negative coding mode. The signed number is found according to the converted value by converting the bitwise-converted multi-bit according to the predetermined mode(S306).

A memory interface part(160) extracts the information being stored in a host memory from the packet according to the analysis result of the header process part and stores information being stored in the host memory in an external memory by using the address allocated from a memory table(170). The header process part comprises at least two queues so as for the queue to access to a receiving processor and a transmission processor respectively. The header process also stores a payload in the external memory by using a memory interface in case that the transmitted packet is the TCP packet having the payload or UDP(User Datagram Protocol) packet.
