  FIG. 2 shows an information processing apparatus 100 including an electronic device such as a PC, and a reader / writer 50, as in FIG. 1 described above. The information processing apparatus 100 includes a communication processing unit 120 that provides an IC card function and a data processing unit 130 that corresponds to the apparatus main body. The communication processing unit 120 performs non-contact communication with the reader / writer 50.

That is, a configuration in which the data processing unit 130 can transmit and receive various data to and from the reader / writer 50 via the communication processing unit 120 is realized.

  As can be understood by comparing the configuration of the information processing apparatus 100 of the present invention shown in FIG. 2 with the configuration of the information processing apparatus 10 described above with reference to FIG. 1, the information processing apparatus of the present invention shown in FIG. The communication processing unit 120 of the apparatus 100 has a simplified configuration compared to the communication processing unit 20 shown in FIG.

Differences between the communication processing unit 120 of the information processing apparatus 100 shown in FIG. 2 and the communication processing unit 20 shown in FIG. 1 are as follows.

  As described above, the configuration of the communication processing unit 120 of the information processing apparatus 100 illustrated in FIG. 2 is simplified. The control unit 123 of the communication processing unit 120 is set as a control logic that executes only simple processing according to a prescribed sequence. Details of specific processing executed by the control unit 123 will be described later.

  For example, the control unit 123 of the communication processing unit 120 does not perform complicated calculations such as a calculation on a received packet from the reader / writer 50 or a generation process of a transmission packet, and performs these processes on the CPU 132 of the data processing unit 130. The control unit 123 of the communication processing unit 120 performs control such as FIFO control as data writing and reading processing using the memory 125 and direction control of data transmission / reception, for example. With such a configuration, the circuit scale and cost can be reduced.

  In the configuration shown in FIG. 1, the data read command from the reader / writer 50 is defined as a read process for the memory 125 of the communication processing unit 120. Similarly, a data write command from the reader / writer 50 is defined as a write process for the memory 125 of the communication processing unit 120.

  In the configuration of the embodiment of the present invention, the control unit 123 of the communication processing unit 120 does not decode an address that is an identifier corresponding to data to be read or written. The address is transmitted to the data processing unit 130 as necessary, and is interpreted by the CPU 132 of the data processing unit 130.

  A processing sequence when a data read processing (read) request is issued from the reader / writer 50 will be described with reference to FIGS.

FIG. 3 is a read processing sequence when data exists in the memory 125 of the communication processing unit 120.
First, in step S101, the writer / writer 50 transmits a data read request to the communication processing unit.
Next, in step S102, the control unit of the communication processing unit 120 sequentially acquires the data stored in the memory 125 in response to the read request. It is a FIFO type memory, and it is only acquired sequentially according to a first-in first-out method.
Next, in step S <b> 103, the communication processing unit 120 transmits the data acquired from the memory 125 to the reader / writer 50.

  Next, a read processing sequence in the case where no data exists in the memory 125 of the communication processing unit 120 during data reading processing (reading) from the reader / writer 50 will be described with reference to FIG.

First, in step S121, the reader / writer 50 transmits a data read request to the communication processing unit.
Next, in step S <b> 122, the control unit 123 of the communication processing unit 120 transmits a command reception interrupt indicating that a read request has been received to the CPU 132 of the data processing unit 130.

  In step S123, the CPU 132 of the data processing unit 130 requests the control unit 123 of the communication processing unit 120 to transfer a command. In step S124, the control unit 123 of the communication processing unit 120 receives a command received from the reader / writer 50. Is transferred to the data processing unit 130 via a wired communication interface.

  In step S125, the CPU 132 of the data processing unit 130 analyzes the output command of the reader / writer 50 transferred from the control unit 123 of the communication processing unit 120. In this command analysis, data requested to be read is determined based on a request data identifier (address or the like) included in the command. The CPU 132 retrieves the determined read request data from the nonvolatile memory 34 in the data processing unit 130 and transmits it to the communication processing unit 120 via the wired interface.

In step S126, the control unit 123 of the communication processing unit 120 sequentially stores the data received from the data processing unit 130 in the memory 125.
Next, the control unit of the communication processing unit 120 sequentially acquires the data stored in the memory 125 in step S127. It is a FIFO type memory, and it is only acquired sequentially according to a first-in first-out method.
Finally, in step S128, the communication processing unit 120 transmits the data acquired from the memory 125 to the reader / writer 50.

  Note that the data transmission processing from the communication processing unit 120 to the reader / writer 50 in step S128 may be set to be executed after waiting until the next read request from the reader / writer 50 is received.

  As described with reference to FIGS. 3 and 4, when the communication processing unit 120 receives a data read request from the reader / writer 50, the data is stored in the memory 125 in the communication processing unit 120. Data is sequentially acquired from the memory 125 and transmitted to the reader / writer 50 without performing communication with the data processing unit 130.

  On the other hand, when the data read request is received from the reader / writer 50, if the data is not stored in the memory 125 in the communication processing unit 120, communication with the data processing unit 130 is executed, and the data processing unit 130 After the data is received and written in the memory 125, the data is sequentially acquired from the memory 125 and transmitted to the reader / writer 50.

  Next, a processing sequence when a data write processing (write) request is issued from the reader / writer 50 will be described with reference to FIG.

  First, in step S131, the reader / writer 50 transmits a data write request to the communication processing unit 120.

  A configuration example of this data write request packet is shown in FIG. As shown in FIG. 6, the data write request includes a command (transmission / reception device) identification information, a header (Head) including transmission data information, a write command (Write), and identification information (address) of data to be written. And a plurality of sets of write data, and a footer including an error check code such as CRC (Cyclic Redundancy Check).

  When receiving the data write packet shown in FIG. 6, the control unit 123 of the communication processing unit 120 sequentially stores the received data from the reader / writer 50 in the memory 125 in step S132. For example, as shown in the memory (FIFO) 125 of the communication processing unit 120 in FIG. 7B, the command (Write) included in the data write request packet, the identification information (address) of the data to be written, and the write data A plurality of sets are written according to the packet data string.

  Next, in step S <b> 133, the control unit 123 of the communication processing unit 120 transmits a command reception interrupt indicating that a write request has been received from the reader / writer 50 to the CPU 132 of the data processing unit 130.

  Next, in step S <b> 134, the CPU 132 of the data processing unit 130 requests the control unit 123 of the communication processing unit 120 to transfer the data written in the memory (FIFO) 125 of the communication processing unit 120.

  The control unit 123 of the communication processing unit 120 sequentially acquires the data stored in the memory 125 in step S135, and outputs the acquired data to the data processing unit 130 in step S136. This transfer data is data written in the memory (FIFO) 125 of the communication processing unit 120 shown in FIG.

  That is, [command (Write)], [address 0 (address 0)], [data 0 (Data 0)], [address 1 (address 1)], [data 1 (Data 1)],... The data is output to the processing unit 130.

  The CPU 132 of the data processing unit 130 acquires this data sequentially, and executes a process of writing the received data to the nonvolatile memory 134 in step S137. As shown in the data stored in the nonvolatile memory 134 of the data processing unit 130 in FIG. 7B, [address 0 (address 0)], [data 0 (Data 0)], [address 1 (address 1)], [data 1 (Data 1)],... Are recorded. The address is recorded in the memory as identification information of each data.

  When the data writing process ends, the CPU 132 of the data processing unit 130 transmits a data writing completion notification to the communication processing unit 120 in step S138.

  Finally, the control unit 123 of the communication processing unit 120 transmits a process completion notification to the reader / writer 50 in step S139.

  Note that the processing completion notification processing from the communication processing unit 120 to the reader / writer 50 in step S139 may be set to be executed after waiting until a processing completion transmission request from the reader / writer 50 is received.

  Note that the data storage capacity of the memory (FIFO) 125 of the communication processing unit 120 may be a capacity capable of recording data for one packet transmitted from the reader / writer 50. If the storage capacity for one packet is secured, when the communication processing unit 120 receives a packet from the reader / writer, communication with the data processing unit 130 is started after all packet data has been written to the memory. It becomes possible.

In the above processing example, the processing executed by the control unit 123 of the communication processing unit 120 is as follows.
(A) In the data read request from the reader / writer,
(A1) Command discrimination processing of received packet from reader / writer,
(A2) Command reception notification processing to the data processing unit (a3) Command transfer processing in response to a command transfer request from the data processing unit,
(A4) Data reception processing from the data processing unit and data writing processing to the memory 125,
(A5) Data acquisition from the memory 125 and output processing to the reader / writer,
These processes are performed.

Also,
(B) In the data write request from the reader / writer,
(B1) Command discrimination processing of received packet from reader / writer,
(B2) Write processing of received data from the reader / writer to the memory 125,
(B3) Command reception notification processing to the data processing unit (b4) Data acquisition from the memory 125 in response to a data transfer request from the data processing unit and output processing to the data processing unit (b5) Data writing processing from the data processing unit is completed Receive notification and send processing completion notification to reader / writer,
These processes are performed.

  As described above, the control unit 123 of the communication processing unit 120 does not execute any advanced processing necessary for substantial data recording or reading such as analysis processing of the data identifier (address) included in the command. The memory grounded to the communication processing unit 120 is a FIFO type, and for data write processing, only data is written sequentially according to the sequence of received packets. In addition, when data is read, it is only read and transmitted in the order of writing. Therefore, memory access can be executed as a very simple process.

  With this configuration, the function of the control unit 123 of the communication processing unit 120 can be lowered, and the program memory and nonvolatile memory in the communication processing unit described with reference to FIG. The capacity can be reduced.

  As described above, the communication processing unit 120 of the information processing apparatus 100 according to an embodiment of the present invention temporarily stores data transmitted and received between the reader / writer 50 that is an external communication device and the data processing unit 130 ( FIFO) 125. Furthermore, it has the control part 123 which performs the data writing and reading control with respect to the memory 125.

  When the command packet received from the reader / writer 50 is a data read request, the control unit 123 executes data acquisition from the memory 125 and transmission processing to the reader / writer 50 and receives the command packet received from the reader / writer 50. Is a data write request, data storage to the memory 125 is executed, and data acquisition from the memory 125 and output processing to the data processing unit 130 are executed in response to a request from the data processing unit 130.

  Further, the control unit 123 of the communication processing unit 120 sends a command to the data processing unit 130 when the command packet received from the reader / writer 50 is a data read request and no data is stored in the memory 125 in the communication processing unit 120. A reception notification transmission process and a command transfer process in response to a request from the data processing unit 130 are executed.

When the command packet received from the reader / writer 50 is a data write request, the data recorded in the memory 125 by the control unit 123 of the communication processing unit 120 and transferred to the data processing unit 130 is
(A) a command included in the received packet, a data identifier and data corresponding to the write target data,
(B) a data identifier and data corresponding to the write target data included in the received packet;
Any of the above settings (a) and (b) may be used.
In the case of (a), command interpretation is executed by the CPU 132 of the data processing unit 130.

  In the case of (b), command interpretation is executed by the control unit 123 of the communication processing unit 120. In this case, the control unit 123 determines whether the command packet received from the reader / writer 50 is a data write request or a data read request, and notifies the data processing unit 130 of the type of the received command. Execute the process.

  Various settings can be made for the processing executed by the control unit 123 of the communication processing unit 120 and the processing executed by the CPU of the data processing unit 130.

  Specifically, for example, the following setting is possible as the processing mode executed by the control unit 123 of the communication processing unit 120 when a command packet is received from the reader / writer.

(A) The header and footer included in the received packet from the reader / writer is read, and the packet syntax check is performed to verify the integrity of the received packet, such as checking the packet error using the CRC stored in the footer. To the output.
(B) In addition to the packet grammar check of (A) above, further command interpretation is performed, and a packet reception notification including the command type is output to the data processing unit.
(C) Only the packet reception notification is executed to the data processing unit without executing the processing for the received packet from the reader / writer.
For example, the setting for performing any one of the processing modes (A) to (C) is possible.

  For example, the control unit 123 of the communication processing unit 120 performs presetting so as to execute any one of the processes (A) to (C). Note that the processing of the CPU of the data processing unit 130 is also changed according to the settings (A) to (C).

  In any of the above settings (A) to (C), the processing of the control unit of the communication processing unit 120 is significantly reduced in function as compared with the function of a CPU mounted on a general IC card. As a result, the hardware cost can be reduced and the device can be downsized.

  In the control unit 123 of the communication processing unit 120, the processes that need to be executed at the minimum are wireless communication with the reader / writer, wired communication with the data processing unit, data storage with respect to the memory (FIFO) 125, and data reading processing. It becomes.

  As the processing mode for the packet, various settings can be made as described above, and one of the above settings is appropriately selected and set according to the cost required for the information processing apparatus, the size of the apparatus, and the like. A configuration is preferable.

  The present invention has been described in detail above with reference to specific embodiments. However, it is obvious that those skilled in the art can make modifications and substitutions of the embodiments without departing from the gist of the present invention. In other words, the present invention has been disclosed in the form of exemplification, and should not be interpreted in a limited manner. In order to determine the gist of the present invention, the claims should be taken into consideration.

  The series of processing described in the specification can be executed by hardware, software, or a combined configuration of both. When executing processing by software, the program recording the processing sequence is installed in a memory in a computer incorporated in dedicated hardware and executed, or the program is executed on a general-purpose computer capable of executing various processing. It can be installed and run. For example, the program can be recorded in advance on a recording medium. In addition to being installed on a computer from a recording medium, the program can be received via a network such as a LAN (Local Area Network) or the Internet, and installed on a recording medium such as a built-in hard disk.

  Note that the various processes described in the specification are not only executed in time series according to the description, but may be executed in parallel or individually according to the processing capability of the apparatus that executes the processes or as necessary. Further, in this specification, the system is a logical set configuration of a plurality of devices, and the devices of each configuration are not limited to being in the same casing.
