  • Publication number: 20240028598
    Abstract: This application provides a transaction processing method performed by a distributed database system, including a coordinating node and a participating node. The coordinating node and the participating node share global memory. The method includes: The coordinating node receives a plurality of query statements sent by a client, creates a transaction based on a first query statement in the plurality of query statements, executes the transaction in the global memory based on a second query statement in the plurality of query statements, and submits the transaction based on a third query statement in the plurality of query statements. Because the global memory can be accessed across nodes without processing performed by a processor and an operating system, an access path is shortened. This implements real-time consistency between the coordinating node and the participating node, and meets a service requirement.

  • Patent number: 9929702
    Abstract: A multi-stage Radio Frequency (RF) power amplifier is presented herein. According to one embodiment, the amplifier comprises: a first amplification stage configured to amplify an input signal to provide a first output signal having a phase distortion; a second amplification stage having an input and configured to amplify the first output signal that is received at the input to provide a second output signal, wherein the second output signal has a carrier frequency (FC) modulated by a signal content (S) having a signal content bandwidth (FS); and a resonant circuit comprising an inductor and a capacitor and having a resonant frequency (FR), the resonant circuit coupled to the input of the second amplification stage and compensating for the phase distortion caused by the first amplification stage at frequencies within the signal content bandwidth FS, wherein the resonant frequency FR is less than the signal content bandwidth FS.
