  The option card 2 includes a communication unit 21, a synchronization unit 22, a storage unit 23, and a processing unit 24.

  The communication unit 21 transmits and receives normal data for applications, the program of the option card 2, version information of the program, and the like with the transfer unit 31 of the control unit 3. The communication means 21 identifies normal data, the program of the option card 2 and the like based on the identification codes given to these data and information. When the communication unit 21 receives an instruction from the transfer unit 31 to transmit the program, the communication unit 21 transmits the program stored in the storage unit 23 to the transfer unit 31 via the synchronization unit 22. The program received from the transfer unit 31 together with the program update instruction is transferred to the synchronization unit 22. When normal data is received, it is transferred to the processing means 24. When the information processing system 10 is activated, the version information of the program stored in the storage unit 23 is transmitted to the transfer unit 31.

  When the information processing apparatus 1 is activated and the communication unit 21 receives a notification of activation from the transfer unit 31, the synchronization unit 22 reads the version information of the program stored in the storage unit 23, adds an identification code, and communicates The data is transmitted from the means 21 to the transfer means 31. In addition, when the communication unit 21 receives an instruction from the transfer unit 31 to transmit the program, the synchronization unit 22 reads the program stored in the storage unit 23 and gives an identification code. Transmit to the transfer means 31. Further, when the synchronization unit 22 receives an update program, that is, a unified version of the program from the communication unit 21, the synchronization unit 22 updates the program stored in the storage unit 23 with the update program. At this time, the storage unit 23 may store the update program in a storage location different from the storage location of the original program.

  The storage means 23 stores a program for operating the option card 2. In addition, an update program, that is, a unified version of the program selected by the comparison means 32 is stored. Also, program version information is stored. Furthermore, normal data may be temporarily stored.

  The information processing apparatus 1 can be an information device such as a server or a PC (Personal Computer). These information devices have a CPU (Central Processing Unit) and a memory. The configuration of the information processing apparatus 1 shown in FIG. 2 can be realized by causing the CPU to operate the program using the computing resources of the CPU and the storage resources of the memory, and to allocate the memory.

  The option card 2 has a CPU and a memory. The configuration of the option card 2 shown in FIG. 2 can be realized by causing the CPU to operate the program using the calculation resources of the CPU and the storage resources of the memory, and further allocating the memory.

  The operation of the information processing system 10 of this embodiment will be described with reference to FIG. FIG. 3 is a flowchart showing an outline of the operation of the information processing system 10.

  (Step S01) First, when the information processing apparatus 1 connected to a plurality of option cards 2 is activated (started), the processing unit 35 of the control unit 3 performs each option by communication between the transfer unit 31 and the communication unit 21. It recognizes the state of the card 2 and initializes it. At this time, the synchronization means 22 of each option card 2 reads the version information of the program in the storage means 23, adds an identification code, and transmits it from the communication means 21 to the transfer means 31. The transfer unit 31 identifies the transmitted version information of the program of each option card 2 and transfers it to the comparison unit 32.

  (Step S02) Next, the comparison means 32 compares the version information of the program of each option card 2, and determines whether there is any difference between them. If there is a difference (YES), the process proceeds to step S03. If there is no difference, exit.

  (Step S <b> 03) When there is a difference in the program version information of each option card 2, the comparison unit 32 selects a version to be unified in order to synchronize each option card 2 with any version. As a method for selecting a unified version, for example, a method of setting the latest version or designating a specific version in advance can be used, but the method is not limited thereto. The comparison unit 32 stores the comparison result and the selected version information in the storage unit 33 in association with the option card 2.

  (Step S04) After the initialization is completed, the notification unit 34 instructs the storage unit 33 to transmit the program when there is a difference in the version of each program and the program version to be unified. To the option card 2 having the program via the transfer means 31. When there are a plurality of option cards 2 having a unified version of the program, for example, by assigning priorities to the option cards 2 in advance, an instruction can be sent to the option card 2 having a higher priority.

  Also, the notification means 34 transfers the option card 2 to which the transfer means 31 transfers the program together with an update instruction in the program when the transfer means 31 receives the program in step S05 described later. Specify 31.

  Upon receiving an instruction to transmit the program, the communication unit 21 identifies the instruction to transmit the program and transfers the instruction to the synchronization unit 22. The synchronization unit 22 reads the corresponding program from the storage unit 23, assigns an identification code, and transfers the program to the communication unit 21. The synchronization means 22 stores the progress at this time in a non-volatile recording area of the option card 2, for example, the storage means 23. The option card 2 may have a non-volatile recording area (not shown) separately from the storage means 23. The data of the program is transmitted from the communication unit 21 to the transfer unit 31.

  (Step S05) Upon receiving the program, the transfer unit 31 stores the program in a work area (not shown) of the transfer unit 31. The work area may be provided in the storage means 33. Further, the transfer unit 31 identifies the program by the identification code, and transfers the program together with the program update instruction to the option card 2 designated in advance by the notification unit 34. The option card 2 that has received the program by the communication unit 21 identifies the program by the communication unit 21 and transfers it to the synchronization unit 22. The synchronization means 22 stores the program in the storage means 23 and updates the program so far with the program. The synchronization unit 22 may store the program in an area different from the storage area of the program in the storage unit 23 so far.

  The synchronization unit 22 notifies the transfer unit 31 of the success or failure of the update to the program via the communication unit 21. When receiving the notification that the update to the program has been successful, the transfer means 31 discards the program stored in the work area and ends. When the transfer unit 31 receives a notification that the update to the program has failed, the transfer unit 31 retransmits the program stored in the work area of the transfer unit 31. Thereafter, the transfer unit 31 repeats retransmission until receiving a notification that the update to the program has been successful.

  In step S04, the synchronization unit 22 that has received an instruction to transmit the program reads out the progress of the operation of reading the program from the storage unit 23, adding the identification code, and transferring the program to the communication unit 21. Stored in the recording area. When the data of the program is read and transferred in small portions, the update by the program can be completed by the following operation.

  That is, in step S05, when the transfer unit 31 receives a notification that the update has been successful, the transfer unit 31 notifies the communication unit 21 of the option card 2 that is the transmission source of the program that the update has been successful. Upon receiving the notification, the option card 2 confirms the progress status stored in the non-volatile recording area at the synchronization means 22, reads out any remaining data of the program, adds an identification code, This progress is stored in the non-volatile recording area. Thereafter, the communication unit 21 transmits the remaining data of the program to the transfer unit 31.

  Thereafter, the operation of step S05 is repeated. That is, the synchronization means 22 of the option card 2 that has received the remaining data of the program adds the remaining data to the already stored data of the program based on the identification code. This process is repeated until all the program data is stored.

  As described above, in the information processing system 10, the information processing apparatus 1 performs the process of updating and synchronizing with the unified version of the program in parallel with the normal operation with another option card already operating with the unified version. This can be done using the free time. In the normal operation, the control unit 3 performs acquisition of data necessary for the operation of the application 4 and transmission of data of an operation result of the application 4 with the option card 2. This is a communication operation that performs transmission and reception.

  In addition, the information processing apparatus 1 may stop operating before the update process is completed. In this case, the update process can be continued by referring to the progress stored in the non-volatile recording area in the option card 2 after the apparatus is started up next time. Also, in this embodiment, even if option cards cannot communicate directly with each other, version mismatch can be resolved without requiring dedicated hardware.

  The information processing apparatus 1 according to the present embodiment includes a control unit 3 that controls a plurality of option cards 2 that operate according to a built-in program. The control unit 3 includes a comparison unit 32 that compares the versions of the programs included in the option cards with each other and selects a unified version when the versions are different. Further, the control unit 3 includes a notification unit 34 that instructs the option card 2 to update the program with a unified version of the program. The option card 2 receives a unified version of the program from the control unit 3, and updates the program with the unified version of the program.

  The control method of the present embodiment is a control method for performing the operation of the information processing system 10 of the present embodiment. That is, the version of the program which each option card of the plurality of option cards operated by the built-in program has is compared with each other. Further, if there is a difference between the versions, a version to be unified is selected. Further, the program is updated with a unified version of the program.
