Abstract: A partition-based method to implement idempotence in an event-driven architecture is provided, which acts to reduce the pressure of database reading and writing, thus improving the performance of event handling. In order to improve parallelism, a consumer cluster (a cluster of multiple consumers that can share the responsibility of processing events) is established such that the events are distributed among different partitions within the cluster. Each partition contains a different consumer worker (with its own cache). An event dispatch module is then used to dispatch events among the consumer workers in a way that keeps the load balanced. In an example embodiment, this is performed by generating a partition identification for an event based on a hash of the context identification of the session established between the user and the application when the event was generated, followed by a modulo operation based on the number of consumer workers in the cluster.

Abstract: This application provides a method for detecting margins of a data signal. A receive end of a data signal may adjust a voltage of a reference power source; adjust, based on a plurality of reference moments included in a reference moment set, a moment of an edge of a data strobe signal transmitted by a transmit end of the data signal; and during the adjustment, for each reference voltage and each reference moment, determine whether a bit error exists in data obtained by decoding the data signal when the voltage of the reference power source is the reference voltage and the moment of the edge of the data strobe signal is the reference moment, to obtain a timing margin of the data signal at each reference voltage and a voltage margin of the data signal at each reference moment.

Abstract: Embodiments herein relate to a temperature-sensing circuit for a semiconductor device. The circuit has a remote temperature-sensing element (RTSE) including a metal thermistor formed in a metal layer on the front side or backside of a substrate. The metal thermistor may be serpentine or spiral shaped. The RTSE communicates with a separate sense circuit at another location such as on the substrate. The RTSE can further include a thin film resistor (TFR) in an adjacent dielectric layer of the stack or within the sense circuit. The RTSE is driven alternately at opposing ends to cancel out the effects of power supply variations. An output voltage which represents a sensed temperature is obtained from a point between the metal thermistor and the TFR for processing by an analog-to-digital converter.

Abstract: The present invention continuously generates a signal at an acceptable frequency without utilizing the PLL to modify the operation of the VCO. When the VCO is initialized properly to output a signal at a specific frequency, the VCO operates on its own to continuously output signals, and the VCO state is modified at regular intervals. Thus, when the interval is short enough and when the VCO is modified to the initial state every time, the VCO state will not deviate significantly from the initial state during these intervals. Thus, the VCO continuously generate signals with frequencies acceptably closed to the specific frequency. That is to say, the invention utilizes the injection lock to modify the operation of the VCO. To compare with the convention skills utilizing the PLL which has to feed back the signal generated by the VCO to the PLL for modifying the VCO state dynamically, the utilization of the injection lock simplifies the hardware and streamlines the process.
