摘要： A redundant computing system is composed of two systems: a first arithmetic processing unit (A-system) and a second arithmetic processing unit (B-system) having the same functions. A diagnosis control unit performs diagnosis of one system while the other system is performing arithmetic processing operation. The diagnosis control unit controls the input to the first and second arithmetic processing units by way of an input control unit according to the diagnosis operation, and an output control unit controls the output from the first and second arithmetic processing units according to the diagnosis result. After termination of the diagnosis, a value is copied from a storage unit of the system which has not been diagnosed to a storage unit of the system which has been diagnosed, and the redundant computing system resumes the redundant operation.

摘要： Current reading means detects an output current of a current source whose output current varies with a variation in temperature and outputs a value proportional to the output current. The temperature of the current source corresponding to the output value of the current reading means which is proportional to the output current of the current source is measured, and a parameter for converting the output value to temperature information is determined from the output value of the current reading means and the measured value of the temperature of the current source corresponding to the output value. The output value of the current reading means is converted to the temperature information using the determined parameter.
