  • Patent number: 11467905
    Abstract: A stripe merging method and system based on erasure codes are provided. A StripeMerge-P algorithm is used first to determine alignment information of parity chunks of erasure code stripes based on a preprocessed hash table. Through a greedy strategy, erasure code stripe pairs to be merged are selected for merging. Through the hash table, location information of the parity chunks is directly looked up, so that no additional computing overhead is required, and the overhead of selecting and merging the erasure code stripe pairs is further reduced through the combination with the greedy strategy.

  • Patent number: 10083117
    Abstract: Technologies are generally described herein to detect non-volatile write request sequences. A write request is received to write to a solid-state device that includes the non-volatile memory. A determination is made as to whether the write request is part of a non-volatile write request sequence or is not part of the non-volatile write request sequence. In response to determining that the write request is part of the non-volatile write request sequence, the write request is associated with the non-volatile write request sequence. In response to determining that the write request is not part of the non-volatile write request sequence, the data associated with the write request is written to a cache that is coupled to the non-volatile memory. The data associated with the non-volatile write request sequences may be written directly to the non-volatile memory.

  • Patent number: 8949099
    Abstract: In a circuit simulation tool in a computer system having one or more computer processors and computer-readable storage, a method for characterizing a driven oscillator circuit having an oscillator coupled to a time-varying input signal includes retrieving information provided in a circuit description of the oscillator circuit. The method also includes forming a frequency-domain harmonic balance equation for the oscillator circuit using the retrieved information provided in the circuit description of the oscillator circuit. The harmonic balance equation includes a first differential operator in a frequency domain of the input signal and a product of a differential operator in a second frequency domain of the oscillator and a frequency variable of the oscillator. The frequency variable is independent of the frequency domain of the input signal. The method further includes solving the harmonic balance equation to obtain a waveform description of the oscillator circuit.

  • Patent number: 8762122
    Abstract: In one embodiment of the invention, a method of simulating a circuit is disclosed including simulating an analog component of the circuit over a first simulation time period with a first envelope simulation; adaptively switching from simulating the analog component with the first envelope simulation to simulating the analog component with a transient simulation over a second simulation time period; and adaptively switching from simulating the analog component with the transient simulation to simulating the analog component with a second envelope simulation over a third simulation time period. The adaptive switching from the first envelope simulation to the transient simulation may be in response to the envelope simulation accuracy falling below a predetermined level of accuracy in comparison with a transient simulation or in response to the second simulation time period including expected digital transitions where one or more digital events may occur to change the analog input signals to the analog component.
