    摘要: A cryptography system comprises a noising engine and a de-noising engine. The noising engine is configured to receive a key pattern, determine a final membership value based on one or more input parameters and a first knowledge base, and generate a noised key pattern based on the key pattern and the final membership value. The de-noising engine is configured to receive the noised key pattern and the final membership value, and generate a de-noised key pattern based on the noised key pattern, the final membership value, and a second knowledge base.

    摘要: A processing system employs a method to order the elements within a memory. Ordering the elements includes receiving an accessed memory element. The accessed memory element is requested by a processor from a memory. Further, the accessed memory element is compared to stored elements within the memory to generate control signals. Gate control signals from the control signals are generated. The order of the stored elements within the memory is updated based on the gate control signals.

    摘要: A voltage driver for supplying a supply voltage includes multiple PMOS transistors, multiple NMOS transistors, a pad, impedance divider circuits, NMOS clampers, and PMOS clampers. A maximum of the supply voltage is N times a maximum of the drain-source voltage of each transistor. The pad is configured to receive a voltage signal for dynamically controlling gates of a subset of the NMOS transistors and a subset of the PMOS transistors. The impedance divider circuits are configured to generate limited voltage signals, each of which is a fraction of voltage between the pad and supply voltage or between the pad and ground. The NMOS clampers and PMOS clampers configured to receive reference voltages and limited voltage signals to generate output, which is in turn input into gate terminals of the subset of NMOS or PMOS transistors.

    摘要: The present disclosure describes systems and methods for generating a superconducting electronic circuit design. The system includes a memory and a processor. The processor simulates a superconducting electronic circuit design using a first process variation to produce a first score and simulates the superconducting electronic circuit design using a second process variation to produce a second score. The processor, in response to determining that the first score is lower than the second score, simulates the superconducting electronic circuit design using the first process variation and a first design variation to produce a third score and simulates the superconducting electronic circuit design using the first process variation and a second design variation to produce a fourth score. The processor updates the superconducting electronic circuit design using the first process variation and the first design variation in response to determining that the third score is higher than the fourth score.

    摘要: A single-ended to a differential signal converter (converter) includes, in part, first, second, and third inverting elements, each having a first size, and coupled in series to form a chain of inverting elements. The converter further includes a fourth inverting element of a second size and coupled to the input of the first inverting element, a fifth inverting element of a third size and coupled to an output terminal of the first inverting element, a sixth inverting element of the third size and coupled to an output of the second inverting element, and a seventh inverting element of the second size and coupled to the output of the third inverting element. The outputs of the fourth and sixth inverting elements form a first one of the differential signals. The outputs of the fifth and seventh inverting elements form a second one of the differential signals.
