  As described above, in a conventional device for a specific application, a computer system is constructed using a plurality of specially designed CPU cards in order to realize intended signal processing and data processing, and each CPU card has , A dedicated OS (Operating System), and application programs. As a result, a computer system that satisfies the installation conditions such as miniaturization and environmental resistance in addition to the functions and performance requirements of the device is realized, but on the other hand, development takes time and the cost tends to increase. was there. On the other hand, in recent years, many general-purpose CPU cards having a similar configuration have been commercially available. Some of these cards can be handled in the same way as conventional dedicated CPU cards, and can be easily obtained, so that this type of general-purpose CPU card can be used to shorten the development period and reduce costs. Attempts have also been made to build computer systems by applying them.

  However, when such a general-purpose CPU card is adopted, a general-purpose OS is installed as basic software. This general-purpose OS is completely different from a conventional small-capacity OS dedicated for a dedicated CPU card, and is a huge one. In addition, there are cases where a combination of middleware and the like is required, so that the entire image file of the basic software has an enormous capacity as compared with the related art. The size of the entire file is, for example, several gigabytes instead of several megabytes in the past. Also, with a general-purpose CPU card, for example, it is not efficient to transfer via a general-purpose common bus line that connects the CPU cards in common as in the related art because the speed of the common bus line is not sufficient. In addition, a general-purpose interface for data transfer with the outside may not be able to obtain a sufficient data transfer rate as compared with a dedicated interface.

By configuring a bus of such a connection method, a sufficiently high-speed data transfer can be performed as compared with a common bus method connected to the same line, a data transfer by LAN, USB, or the like, which has been frequently used in the past. I have to.

  In the computer system 1 of the present embodiment, the backplane 30 is housed in a chassis, and the host CPU 10 and the CPU card 20 are mounted in slots of the backplane, so that the entire system is integrated into a VPX chassis. You can also. FIG. 2 is a conceptual diagram showing a modeled example of the configuration of the VPX chassis. FIG. 2A illustrates a modeled case where the host CPU 10 is mounted in slot 1 of the VPX chassis and the CPU card 20 is mounted in slots 3 and 7, respectively.

  Further, the configuration of the card mounted in each slot is defined in advance in the configuration of the computer system 1, for example, in a slot configuration table having the contents shown in FIG. 2B. In the example of FIG. 2B, in addition to the correspondence between the slot number and the card name, the transfer destination slot after each card receives the file for initial installation of the basic software group, and the installation at the transfer destination , Control information including a base address necessary for the control is defined. The slot configuration table is stored in, for example, the remote terminal 2 or the like, which is an external device, and is transferred together with a file for initial installation of the basic software group.

  Next, with reference to FIGS. 1 and 2 and the flowcharts of FIGS. 3 to 8 described above, the operation of the computer system 1 according to the present embodiment configured as described above will be described. The explanation focuses on the initial installation of. In the following description, the configuration of the computer system 1 is based on a case where two CPU cards 20 (n = 2) in the block diagram of FIG. 1 are housed in a VPX chassis as in the case of FIG. 2 described above. Has been taken up.

  That is, the host CPU 10, the two CPU cards (1) 20 (# 1), and the CPU cards (2) 20 (# 2) are respectively connected to the first of the VPX chassis as illustrated in FIG. , Third, and seventh slots, and are connected by the above-described data bus (1) 31 (VPX bus). As a slot configuration table, as illustrated in FIG. In addition to the correspondence between the number and the card name, the slot number of the transfer destination after each card receives the installation file, and control information including the base address required for installation at the transfer destination are defined. The case has been taken up. It is assumed that a file for initial installation of the basic software group and the slot configuration table described above are held in the remote terminal 2 in advance.

  FIG. 3 is a timing chart showing an example of the entire flow at the time of initial installation of the basic software group. First, only the overall flow will be described. When the target basic software group is initially installed in the computer system 1, the installation file and the slot configuration table held in the remote terminal 2 are transmitted from the remote terminal 2 via the data bus (2) 32 (LAN). Then, the file and the slot configuration table in the computer system 1 are transferred to the CPU card 10 in the computer system 1 and the data bus (1) 31 (VPX) is exchanged between the cards mounted in the adjacent slots. The basic software group is initially installed in each card while being sequentially transferred via a bus) like a relay system.

  That is, referring to FIG. 3, first, after the slot configuration table and the file of the basic software group are transferred from the remote terminal 2 to the host CPU 10 via the LAN 32, the start of the installation is instructed (see FIG. 3). A in 3). In the host CPU 10 (# 1), the transferred slot configuration table and file are temporarily stored internally, and then the VPX bus 31 is connected to the CPU card (1) 20 (# 1) mounted in the adjacent slot. In addition to the transfer of the file including the instruction to start the installation (B in FIG. 3), the stored files of the basic software group are expanded in the own card based on the instruction to start the installation, and are stored in the large-capacity storage unit. The basic software group is installed in a predetermined area in the area 13 (C in FIG. 3).

  Similarly, in the CPU card (1) 20 (# 1), the slot configuration table and file transferred from the host CPU 10 are temporarily held therein, and then temporarily stored in the CPU card (2) 20 (# 2) in the adjacent slot. ) Is transferred via the VPX bus 31 together with an instruction to start the installation (D in FIG. 3), and the files of the basic software group are expanded in the own card, and a predetermined area in the large-capacity storage unit 23 is stored. Is installed (E in FIG. 3).

  Further, in the CPU card (2) 20 (# 2), the slot configuration table and the file transferred from the adjacent CPU card (1) 20 (# 1) are temporarily stored therein, and then the card is stored in the VPX. Since it is installed at the end of the slot arrangement of the chassis, there is no transfer destination of the file, and the basic software group is installed in a predetermined area in the mass storage unit 23 in the own card based on the installation start instruction. (F in FIG. 3). Then, the installation status, which is the installation result of each card, is sequentially transferred in the reverse direction, collected by the host CPU 10, and notified to the remote terminal 2 (G in FIG. 3).

  Next, the operation of the remote terminal 2 will be described with reference to FIG. FIG. 4 is a flowchart for explaining the operation of the remote terminal 2 at the time of initial installation of the basic software group. When the remote terminal 2 starts a control operation for installation, first, the remote terminal 2 sends a slot configuration table to the host CPU 10 (ST41). Next, in order to transfer a file for installation, a file reception start command is transmitted to the host CPU 10 to instruct start of file reception (ST42), and a checksum and a file size of a file for detecting a transfer error. Is notified (ST43).

  Next, after confirming that these have been received by the host CPU 10 (ST44), transmission of the file body is started (ST45). Then, when the transmission of the file body is completed (ST46), an installation start command is transmitted to instruct to install the basic software group in the own card (ST47). Thereafter, the installation status is received from each card to confirm the installation result (ST48). Note that various data transfers between the remote terminal 2 and the host CPU 10 are performed via the data bus (2) 32 (LAN). Control for such installation is performed by an application program or the like stored in the remote terminal 2 in advance.

  Next, the operation of the host CPU 10 will be described with reference to FIG. FIG. 5 is a flowchart for explaining the operation of the host CPU 10 at the time of initial installation of the basic software group.

  First, the host CPU 10 receives the slot configuration table sent from the remote terminal 2, temporarily stores the slot configuration table in a predetermined area in the large-capacity storage unit 13 (ST 501), and connects each card in the computer system 1. According to the standard of the VPX bus which is the data bus (1) 31 to be used, the slot position information of the card is acquired by the Geographical Address (ST502). Next, a series of commands for transferring and installing the file and the file itself are received from the remote terminal 2. That is, it receives the file reception start command from the remote terminal 2 and starts preparation for reception (ST503). After receiving the checksum and file size of the file to be transferred (ST504), it receives the file itself (ST505) and further installs. A start command is received (ST506). The data transfer between these remote terminals 2 is performed via the data bus (2) 32 (LAN).

  Next, based on the slot configuration table and the slot position information, an adjacent slot to which a file is to be transferred and a card mounted in the slot are specified. In the present embodiment, it is specified that the transfer destination is the CPU card (1) 20 (# 1) (ST507). Next, the slot configuration table and the installation file received from the remote terminal 2 are transferred to the CPU card (1) 20 (# 1) mounted in the adjacent slot. This transfer operation is the same as a series of operation steps of ST41 to ST46, which are operation steps when transferring these files from the remote terminal 2 to the host CPU 10.

  That is, the slot configuration table, the file reception start command, the file checksum and file size, and the file body are sequentially transmitted (ST508), and thereafter, the installation start command corresponding to the operation step of ST47 is transmitted (ST509). The transfer of commands and files between the host CPU 10 and the CPU card (1) 20 (# 1) is performed at high speed via the PCI Express bus in the VPX bus which is the data bus (1) 31.

  Next, the basic software group is initially installed on the own card. That is, based on the installation start command received in the operation step of ST 506, the installation file transferred from the remote terminal 2 and temporarily stored is expanded while checking its checksum, and the large-capacity storage unit 13 is expanded. The basic software group is installed in a predetermined area (ST510), and an installation status as an installation result is obtained (ST511). Then, after the installation status of each card returned from each CPU card 20 of the file transfer destination is collected, these are output to the remote terminal 2 for notification (ST512).

  FIG. 6 shows an example of a map of the storage area of the large-capacity storage unit 13 in the host CPU 10. FIG. 6 is a diagram modeling and showing an example of the contents of the storage area of the large-capacity storage unit 13 after various programs and the like are installed. In FIG. 6, the boot loader stored in / boot is executed immediately after the power is turned on to the host CPU. In this embodiment, the boot loader loads the installation control program (1) stored in / inst1 into the memory 12.

  The installation control program (1) is a control program for the host CPU 10 to execute the operation of FIG. 5 described above, and is transferred from the remote terminal 2 by executing the installation control program (1) on the memory. Are temporarily stored in / temp1 and further transferred to the CPU card 20 in the adjacent slot, and these files are expanded to install the basic software group in the own card. The boot loader and the installation control program (1) are stored in the mass storage unit 13 in advance.

  The basic software group (1) from / os1 is an area where the basic software group is thus installed. Further, in this case, another basic software group (2) used for maintenance of the equipment such as failure detection and software update is installed in a predetermined area / os2. At the time of this installation, the same method as that of the basic software group (1) can be applied.

  Next, the operation of the CPU card 20 will be described with reference to FIG. FIG. 7 is a flowchart for explaining the operation of the CPU card 20 at the time of initial installation of the basic software group. In this embodiment, two CPU cards (1) 20 (# 1) and CPU cards (2) 20 (# 2) are mounted, and in the following description, one adjacent slot is used. The mounted card is the host CPU 10 in the case of the CPU card (1) 20 (# 1), and is the CPU card (1) 20 (# 1) in the case of the CPU card (2) 20 (# 2). is there.

  First, CPU card 20 receives a slot configuration table sent from a card mounted in one of the adjacent slots, and temporarily stores the slot configuration table in a predetermined area in large-capacity storage unit 23 in the own card (ST701). . At the same time, CPU card 20 acquires the slot position information of its own card by the Geographical Address according to the VPX bus standard (ST702). Next, a series of commands for file transfer and a file main body are received from a card mounted in one adjacent slot. That is, it receives a file reception start command, a checksum and a file size of a file to be transferred, and a file body (ST703), and further receives an installation start command (ST704).

  Next, based on the slot configuration table and the slot position information, it is determined whether or not the CPU card 20 is installed in the other adjacent slot to which the file is to be transferred. As a result of the determination, if the CPU card 20 is mounted (Y in ST705), the CPU card 20 is specified as a file transfer destination, and a slot configuration table and an installation file Is transferred (ST706), and an installation start command is transmitted (ST707). This transfer operation is similar to the operation of ST508 to ST509 in host CPU 10 in FIG. On the other hand, when CPU card 20 is not mounted in the other adjacent slot (N in ST705), transfer and command transmission are not performed.

  In this embodiment, in the case of the CPU card (1) 20 (# 1), the card mounted in the other adjacent slot is the CPU card (2) 20 (# 2), which is used as the transfer destination. Identify and perform file transfer. On the other hand, in the case of the CPU card (2) 20 (# 2), there is no card mounted in the other adjacent slot, and no transfer is performed.

  Next, the basic software group is initially installed on the own CPU card. That is, based on the installation start command received in the operation step of ST704, the installation file temporarily transferred from the card in one of the adjacent slots is expanded while confirming its checksum, and expanded. The basic software group is installed in a predetermined area of the capacity storage unit 23 (ST708). After the installation is completed, an installation status as an installation result is obtained (ST709), and transmitted to the host CPU (ST710). The transfer of commands and files between the cards mounted in the above-described adjacent slots is performed at high speed via the PCIExpress bus in the VPX bus which is the data bus (1) 31.

  FIG. 8 shows an example of a map of the storage area of the large-capacity storage unit 23 in the CPU card 20. FIG. 8 is a diagram illustrating a modeled content of the storage area of the large-capacity storage unit 23 in the CPU card 20 after various programs and the like are installed. In the present embodiment, the large-capacity storage unit 23 has storage contents and mapping similar to those of the large-capacity storage unit 13 in the host CPU illustrated in FIG. 6, and a program for realizing the operation in FIG. The basic software group is stored in advance in / inst2 as the installation control program (2), and is initially installed in the area of / os1. The other areas are the same as those of the large-capacity storage unit 13, and the description is omitted.

  As described above, in the computer system of the present embodiment, as the bus interface between the host CPU 10 and the CPU card 20, there are provided a plurality of connecting portions which can be connected to the PCI Express bus, and these cards are mounted on the backplane 30. In this state, the connection portions of the cards are connected in a daisy chain to form a VPX bus. Then, high-speed transfer of a large-capacity file is enabled between these cards in the own computer system.
