PROBLEM TO BE SOLVED: To facilitate exclusive control to protocol control information, and to reduce a needed memory capacity.SOLUTION: An information processor for managing protocol control information to be used for communication protocol processing, includes: a plurality of processing parts for executing communication protocol processing; a first storage part for storing protocol control information; and a second storage part for storing protocol control information to be used by the processing parts. Data transfer between the first storage part and the second storage part is executed on the basis of an instruction of the processing parts. A semaphore corresponding to the protocol control information stored in the second storage part is managed. After acquiring a semaphore corresponding to the protocol control information stored in the second storage part and to be used by the processing parts, access to the protocol control information by processing means is executed. |
