INFORMATION-PROCESSING APPARATUS, INFORMATION-PROCESSING METHOD, AND PROGRAM

摘要

An information-processing method performed in an information-processing apparatus, the information-processing apparatus performing wireless communication with a first apparatus and wire communication with a second apparatus, the information-processing method including the steps of:
transmitting an interrupt signal to the second apparatus by using the wire communication when data is received from the first apparatus;receiving, by using the wire communication, a clock signal from the second apparatus which receives the interrupt signal; andtransmitting and receiving, by using the wire communication, data between the information-processing apparatus and the second apparatus.

主权项

1. An information-processing apparatus comprising:
communication means configured to communicate with a reader/writer; a module configured to control the communication means; a processing means configured to transmit and receive data to and from the module, respectively; an interrupt-signal output means configured to output an interrupt signal from the module to the processing means when the communication means receives data from the reader/writer; a clock-signal output means configured to output a clock signal from the processing means to the module when the interrupt signal is received; a data output means configured to output data, in synchronization with the clock signal, from the module to the processing means or from the processing means to the module; and a switching-signal output means through which the processing means outputs a switching signal used for switching the direction of data transmission and reception; wherein the module outputs the interrupt signal, and transmits data-length data when the clock signal is received, the data-length data indicating a data length of data to be transmitted to the processing means; and the processing means counts the data length of data, the data being transmitted from the module by the data output means and received, after the data-length data indicating the data length is received, and determines the termination of data output from the module when the count value is equal to or greater than the data length indicated by the data-length data.
