    摘要： An electronic fault detection unit is provided that has a first register, a second register, a comparator circuit, and a timer circuit. The first and second register can be written from a first software portion, and a second software portion, respectively. The comparator circuit is arranged to detect that both the first and second register have been written, verify a relationship between first data written to the first register and second data written to the second register, and signal a fault upon said verification failing. The timer circuit is arranged to signal a fault if said verification of the comparator circuit does not occur within a time limit.

    摘要： Conventional semiconductor devices are problematic in that an operation cannot be continued in the event of a failure of one of CPU cores performing a lock step operation and, as a result, reliability cannot be improved. The semiconductor device according to the present invention includes a computing unit including a first CPU core and a second CPU core that perform a lock step operation, wherein the first CPU core 11 and the second CPU core 12 respectively diagnose failures of internal logic circuits, and a sequence control circuit switches the CPU core that outputs data to a shared resource, in the computing unit based on the diagnose result.

    摘要： A computer-implemented method for managing storage devices in a storage subsystem having an array of storage devices, according to one embodiment, includes determining that at least one storage device in the array of storage devices has failed. Storage device characteristics of the failed storage device are compared with storage device characteristics of each of a plurality of candidate devices, and an attempt is made to identify a first candidate storage device having storage device characteristics that match the storage device characteristics of the failed storage device. A second candidate storage device having storage device characteristics most similar to the storage device characteristics of the failed storage device is identified in response to not identifying a candidate device that matches the failed storage device.

    摘要： Methods and systems for a scalable self-checking processing platform are described herein. According to one embodiment, during an execution frame, a first processing element executes both a high-criticality application and a first low-criticality application. During that same execution frame, a second processing element executes both the high-criticality application and a second low-criticality application. The high-criticality application output from the first processing element is compared with that from the second processing element before the next execution frame, and a fault occurs when the output does not match. The low-criticality application is not duplicated or compared. This and other embodiments allow high-criticality applications to be appropriated checked while avoiding the over-dedication of resources to low-criticality applications that do not warrant self-checking.

    摘要： A control unit has two pairs of execution units, the two execution units of each pair redundantly processing the same program, and the output signals of each execution unit of one pair being compared to one another by a respective comparing unit, the respective comparing unit outputting an error signal when a difference in the output signals of the execution units of one pair occurs. A first pair of execution units are shut down when the error signal occurs for the first pair, and the control unit continues control operation using the second pair of execution units, and a pre-warning signal is output to the driver.
