[0052] [Structure of the control device]

[0053] figure 1 It is a configuration diagram of the control unit 1 including the control device 100-1 and the control device 100-2. figure 1 The shown control device 100-1 and the control device 100-2 respectively perform processing related to the control of the target device TG-1 and the target device TG-2 of control targets, for example. The target device TG-1 and the target device TG-2 may be separate devices or integral devices. In the latter case, the target device TG-1 and the target device TG-2 respectively control different functions of the same device. It should be noted that, in figure 1 In the description of , the hyphen in the label and the number following it indicate which control device corresponds to the structure. In addition, a hyphen and subsequent numerals may be appropriately omitted for description.

[0112] According to the first embodiment described above, it is provided with: the failure determination unit 104, which determines whether a failure has occurred in the monitoring object based on the state of the monitoring object; and the storage unit 300, which stores a The FOF part 112 of the function related to the operation of the monitoring object; and the FOF generating part 106, when the failure judging part 104 determines that the monitoring object has a fault, the FOF generating part 106 generates the FOF part 112, thereby, Using the flexible structure of the reconfigurable FPGA, the FOF unit 112 dedicated to dealing with failures can be realized only when a failure occurs.

[0113] In addition, according to the control device 100 of the first embodiment, the FPGA can be used only for the control of the target control unit 114 in normal times, so it is possible to allocate as much memory area as possible for the target control unit 114 in normal times. On the other ...

Abstract

The invention provides a control device, a control unit, a control method, and a storage medium. The flexible structure of a reconstruct-able arithmetic unit is utilized to realize a specific functionfor fixing the fault, when a fault happens. A control device includes: a determination unit that determines whether or not a malfunction has occurred in a monitoring target on the basis of a state ofthe monitoring target; an arithmetic unit that is capable of re-configuring a function; a storage unit that stores software used for causing the arithmetic unit to reconfigure a function relating toan operation of the monitoring target; and a processing unit that reads the software from the storage unit and reflects the software on the arithmetic unit in a case in which it is determined by the determination unit that a malfunction has occurred in the monitoring target.

Description

technical field [0001] The invention relates to a control device, a control unit, a control method and a storage medium. Background technique [0002] Conventionally, technologies related to reconfigurable devices (calculators) typified by FPGAs (Field Programmable Gate Arrays) have been disclosed (for example, Japanese Patent Laid-Open No. 2001-136058). In the technology described in Patent Document 1, based on the fault information and logic circuit data existing on the FPGA, it is determined whether fault avoidance is necessary. If fault avoidance is required, the function of the faulty part is replaced by an idle part of the FPGA. The logic circuit data is partially changed to generate logic circuit data that avoids failure. [0003] However, in the conventional technology, it is assumed that a free area for logic circuits is prepared in advance, and there is a possibility that appropriate failure avoidance cannot be performed if resources are not sufficiently free. C...
