    摘要: A telephone call diverting and answering system. The system includes a telephone call concentrator for diverting a telephone call placed at a telephone set at one of a number of calling stations, from a telephone line connected to the intended telephone set, at one of a large number of called stations, to one of a small number of telephone trunks leading to sets at a number of answering stations. The system further includes an operator console at each answering station, and a traffic director for assigning the call to a particular station by causing the identity of the called station and the number of the diverting trunk to be displayed on the operator console of the assigned answering station.

    摘要: Methods and systems redundantly validate values that are stored in a memory arrangement. The memory arrangement includes a first port and a second port that provide coherent access to one or more caches in the memory arrangement, and the first and second ports provide this coherent access at the same priority level. An instruction processor verifies that a first expected value matches a first check value calculated from the values as read from the memory arrangement via the first port. A check circuit verifies that a second expected value matches a second check value calculated from the values as read from the memory arrangement via the second port. A recovery operation is performed in response to the first or second expected values not matching the first and second check values, respectively.

    摘要: Systems and methods are provided for identifying an atomic element in proximity to an integrated circuit. Trace amounts of a contaminant are identifiable. The atomic element is exposed to neutron radiation to convert a portion of the atomic element into a radioactive isotope of the atomic element. Upsets are measured for the binary states of the memory cells of the integrated circuit during a time period following the exposure to the neutron radiation. The atomic element is identified from the upsets of the binary states of the memory cells of the integrated circuit.

    摘要: In one embodiment, a method is provided for determining a level of resilience of a circuit to single event upsets based on a layout of a circuit design. A set of locations in the layout of the circuit design is selected. A respective maximum level of linear energy transfer (LET) that is tolerable for each location in the selected set is determined. For each determined maximum level of LET, cross-section values at locations having the maximum level of LET are summed to determine a respective total cross-section value for the maximum level of LET. For each determined maximum level of LET, the total cross-section value is divided by the determined maximum level of LET to produce respective intermediate values. The respective intermediate values are summed to determine a level of resilience.

    摘要: An embodiment of the invention relates to an integrated circuit such as an FPGA wherein a stable unique identifier is produced by reading an intrinsic characteristic of the IC such as a physically unclonable function, and a related method. In one embodiment, a first unique identifier is generated using the intrinsic characteristic and is subdivided into a plurality of first subsets. A second unique identifier is received and subdivided into a plurality of second subsets. The first and second subsets are compared to identify matching subsets to generate the stable unique identifier. Each of the one or more matching subsets includes a particular one of the plurality of first subsets that matches a corresponding one of the plurality of second subsets. The stable unique identifier can be integrated into logic of the IC. Prior to comparing the subsets, the first and second subsets can be transformed with one-way functions.

    摘要: A method and apparatus for the detection and correction of soft errors existing within an integrated circuit (IC). Run-time check stops are utilized in conjunction with processor-based, hardware mechanisms to detect and correct soft errors. At run-time, each check stop facilitates a snap shot of the hardware and/or software state of the IC to be stored into hardware and/or software based memory. Should a soft error be detected, execution is halted and the executable state of the IC that conforms to a previous check-stop location may be re-established after the soft error(s) are optionally corrected. In alternate embodiments, hardware based mechanisms may be exclusively utilized to both detect and correct the soft errors.
