摘要： PROBLEM TO BE SOLVED: To provide a motor generator driving controller which can more certainly prevent the expansion of failure of elements of a motor generator driving circuit due to a short circuit current during degenerative operation. SOLUTION: The rotating speeds of two motor generators and a trouble in inverter devices connected to the motor generators respectively are detected by a degenerative operation indication section 310. When any trouble is detected, a controller 300 stops the operation of the inverter for which a trouble has been detected and outputs an operation command which brings the motor generator connected to the stopped inverter device into such a state that it may rotate following the movement of the other motor generator. When the rotating speed N1 of the motor generator being thus rotated exceeds a predetermined allowable rotating speed N1max, a rotating speed indication section 330 outputs such an operation command (rotation control) as to reduce the rotating speed N2 of the motor generator connected to the inverter device with no trouble.

摘要： PROBLEM TO BE SOLVED: To improve the fault resistance and reliability of an information processor by increasing the probability that an uncorrectable fault becomes correctable if the uncorrectable fault is detected even when an ECC (error correcting code) is used for data in a cache memory. SOLUTION: If the uncorrectable fault which can not be corrected even with the ECC occurs to the cache memory, duplicates of data with high cache hit frequencies are held in the cache memory to increase the redundancy of data and also improve the fault resistance without extending a memory. Further, duplicate data are generated by using the spatial localization and temporal localization of the cache memory to increase the redundancy of the cache memory and the fault resistance without extending the cache memory.
