摘要： The disclosed invention provides a structure and method for detecting address line (e.g., wordline, bitline) memory failures. In one embodiment, the method and structure comprise generating an address signature, by re-encoding an internally generated address signal from activated elements (e.g., wordlines) inside a memory array. The regenerated address signature may be compared with a requested memory address location. If the regenerated address signature and memory location are equal than there is no error in the memory array, but if the regenerated address signature and memory location are equal than an error is present in the memory array. Accordingly, re-encoding an address signature provides a closed loop check that a wordline and/or bitline, that was actually activated in a memory array, was the correct requested wordline and/or bitline, that no other wordlines or bitlines were also triggered, and that the wordline and/or bitline is continuous.

摘要： Some embodiments of the invention relate to a single processor configured to comprise configurable hardware extensions, disposed within a data path configured to selectively provide either encoded data or original data, that allow for two modes of operation. In a high performance mode, the hardware extensions allow for increased processing bandwidth by using the hardware extensions for processing extended data (i.e., additional original data). In a safety integrity mode the hardware extensions allow for parallel processing of encoded data concurrent with the processor executing a SBST by processing a self-test program and self-test data. Therefore, the single channel processor provides a single core system that can selectively achieve either high safety integrity levels (e.g., SIL3) for safety relevant applications or high performance for non-safety relevant applications.

摘要： An Error signal handling comprises a circuitry configured to receive an error signal from an external device indicating an error condition in the external device. The circuitry is further configured to receive a recovery signal indicating a mitigation of the error condition in the external device or indicating that a mitigation of the error condition in the external device is possible. Furthermore, the circuitry is further configured to output an error condition signal based on the error signal in response to a reception of the error signal if within a given delay time from the reception of the error signal, the circuitry does not receive the recovery signal and otherwise to omit outputting the error condition signal.
