  • Patent number: 10978130
    Abstract: Methods, systems, and devices for temperature-based access timing for a memory device are described. In some memory devices, accessing memory cells may be associated with different operations that are variously dependent on a temperature of the memory device. For example, some operations associated with accessing a memory cell may have a longer duration and others a shorter duration depending on the temperature of the memory device. In accordance with examples as disclosed herein, a memory device may be configured for performing some portions of an access operation according to a duration that is proportional to a temperature of the memory device, and performing other portions of the access operation according to a duration that is inversely proportional to a temperature of the memory device.

  • Patent number: 10917203
    Abstract: Embodiments use Bayesian techniques to efficiently estimate the bit error rates (BERs) of cables in a computer network at a customizable level of confidence. Specifically, a plurality of probability records are maintained for a given cable in a computer system, where each probability record is associated with a hypothetical BER for the cable, and reflects a probability that the cable has the associated hypothetical BER. At configurable time intervals, the probability records are updated using statistics gathered from a switch port connected to the cable. In order to estimate the BER of the cable at a given confidence level, embodiments determine which probability record is associated with a probability mass that indicates the confidence level. The estimate for the cable BER is the hypothetical BER that is associated with the indicated probability mass. Embodiments store the estimate in memory and utilize the estimate to aid in maintaining the computer system.

    Abstract: Systems and methods for classifying a modulation scheme of a wireless signal are described. In some embodiments, a system receives a wireless signal modulated based on a modulation scheme having a constant modulus. The system can generate a resampled signal from the wireless signal based on features extracted from the wireless signal and perform blind equalization on the resampled signal based on a constant modulus criterion to generate an equalized signal. Then, the system can cause a modulation classifier to classify the received wireless signal to a modulation scheme from a plurality of predetermined modulation schemes based on the equalized signal. By preconditioning the wireless signal to reduce feature variability imparted by a propagation channel onto the wireless signal, the system can increase the classification accuracy of the modulation classifier.

  • Patent number: 10671553
    Abstract: Differing widths of retimers are developed using differing numbers of individual retimer elements combined together. To maintain synchronous operation, various signals are provided between the individual retimer elements to allow synchronization of the various operations. A first signal is a wired-OR signal that is used for event and operation synchronization. A second set of signals form a serial bus used to transfer proper state information and operation correction data from a master retimer element to slave timer elements. The combination of the wired-OR signal and the serial bus allow the various state machines and operations inside each retimer element to be synchronized, so that the entire width of the link is properly synchronized.

  • Patent number: 10659095
    Abstract: A circuit for direct current (DC) offset estimation comprises a quantile value circuit and a signal processor. The quantile value circuit determines a plurality of quantile values of an input signal and includes a plurality of quantile filters. Each quantile filter includes a comparator, a level shifter, a monotonic transfer function component, and a latched integrator. The comparator compares the input signal and a quantile value. The level shifter shifts the output of the comparator. The monotonic transfer function component determines the magnitude of the shifted signal and provide a transfer function signal. The latched integrator suppresses transient characteristics of the transfer function signal and provide the quantile value. The signal processor is configured to calculate a weighted average of the quantile values to yield a DC offset estimate.
