摘要： A wireless communications system includes: a first communications processing section for implementing a dedicated communications function that is only for the first wireless communications scheme; a second communications processing section for implementing a dedicated communications function that is only for the second wireless communications scheme; a shared transceiver section shared by the first communications processing section and the second communications processing section; a scheme selection section for selectively inputting a signal from the first communications processing section or a signal from the second communications processing section to the shared transceiver section; and a communications switching control section for indicating, to the scheme selection section, a scheme to be selected. The communications switching control section determines a switching timing based on frame and sub-frame information from the first communications processing section in an operation of switching from the first wireless communications scheme to the second wireless communications scheme or an operation of searching for a communications target station using the second wireless communications scheme.

摘要： Input data is stored in input buffers provided for respective input channels. An operation channel control section controls an input data selector to allow the data stored in the input buffers to be input into an operation circuit by the block unit in a time-division manner. The operation circuit encrypts (or decrypts) the input data with an encryption key given from an encryption key selector.
