Abstract

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; and
  • transmitting and receiving, by using the wire communication, data between the information-processing apparatus and the second apparatus.

Claims

1. An information-processing apparatus, comprising:

a first line, included in a predetermined interface, for transmitting an interrupt signal to a second apparatus, connected using the interface, when data is received from a first apparatus;

a second line, included in the interface, for receiving a clock signal from the second apparatus; and

a third line, included in the interface, for transmitting or receiving data to or from the second apparatus, and

wherein the data from the first apparatus includes command data, the command data is analyzed when the data from the first apparatus is received to determine whether supply of second data of the data to the second apparatus, in which the second data is other than the command data, is necessary, and the interrupt signal is transmitted to the second apparatus in response to a result of analysis of the command data being the supply of the second data to the second apparatus is necessary.

2. The information-processing apparatus according to claim 1, wherein the data from the first apparatus includes, in the second data, data-length data and main data, in which the data-length data indicates a data length of the main data to be transmitted to the second apparatus, and

wherein the main data is transmitted to the second apparatus through the third line after the data-length data is transmitted to the second apparatus, in synchronization with the clock signal from the second apparatus.

3. The information-processing apparatus according to claim 1, further comprising;

a fourth line, included in the interface, for receiving a signal from the second apparatus, the signal indicating whether data is to be transmitted to or received from the second apparatus, and

wherein the information-processing apparatus detects whether data is to be transmitted to the second apparatus or data transmission thereto is terminated based on a changeover in a state of the signal transmitted through the fourth line.

4. An information-processing apparatus, comprising:

a first line, included in a predetermined interface, for transmitting an interrupt signal to a second apparatus, connected using the interface, when data is received from a first apparatus;

a second line, included in the interface, for receiving a clock signal from the second apparatus; and

a third line, included in the interface, for transmitting or receiving data to or from the second apparatus, and

wherein the data from the first apparatus includes command data, the command data is analyzed when the data from the first apparatus is received, and the interrupt signal is transmitted to the second apparatus in response to a result of analysis of the command data, wherein the data from the first apparatus includes data-length data and main data, in which the data-length data indicates a data length of the main data to be transmitted to the second apparatus, and

wherein, upon receipt of the data-length data, the information-processing apparatus analyzes the command data and

(i) when the result of the analysis indicates that the main data should be supplied to the second apparatus the information-processing apparatus supplies the data-length data and the main data to the second apparatus and does not supply the command data to the second apparatus, and

(ii) when the result of the analysis indicates that the main data should not be supplied to the second apparatus the information-processing apparatus does not supply the main data to the second apparatus.

5. An information-processing apparatus, comprising:

a communication unit configured to communicate with a reader/writer;

a module configured to control the communication unit;

a processing unit configured to transmit and receive data to and from the module;

wherein the module comprises;

a first line, included in a predetermined interface, for transmitting an interrupt signal to a second apparatus, connected using the interface, when data is received from the reader/writer;

a second line, included in the interface, for receiving a clock signal from the processing unit; and

a third line, included in the interface, for transmitting or receiving data to or from the processing unit; and

wherein the data from the reader/writer includes command data, the command data is analyzed when the data from the first apparatus is received to determine whether supply of second data of the data to the second apparatus, in which the second data is other than the command data, is necessary, and the interrupt signal is transmitted to the second apparatus in response to a result of analysis of the command data being the supply of the second data to the second apparatus is necessary.

6. An information processing method comprising:

transmitting, through a first line included in a predetermined interface, an interrupt signal to a second apparatus, when data is received from a first apparatus;

receiving, through a second line included in the interface, a clock signal from the second apparatus; and

transmitting or receiving data to or from the second apparatus, through a third line included in the interface,

wherein the data from the first apparatus includes command data, the command data is analyzed when the data from the first apparatus is received to determine whether supply of second data of the data to the second apparatus, in which the second data is other than the command data, is necessary, and the interrupt signal is transmitted to the second apparatus in response to a result of analysis of the command data being the supply of the second data to the second apparatus is necessary.

7. A non-transitory storage medium on which is recorded a computer readable program, the program comprising:

transmitting, through a first line included in a predetermined interface, an interrupt signal to a second apparatus, when data is received from a first apparatus;

receiving, through a second line included in the interface, a clock signal from the second apparatus; and

transmitting or receiving data to or from the second apparatus, through a third line included in the interface,

wherein the data from the first apparatus includes a command, the command is analyzed when the data from the first apparatus is received to determine whether supply of second data of the data to the second apparatus, in which the second data is other than the command data, is necessary, and the interrupt signal is transmitted to the second apparatus in response to a result of analysis of the command being the supply of the second data to the second apparatus is necessary.
