Abstract: Embodiments of the present invention provide a digital-to-analog conversion circuit, where the digital-to-analog conversion circuit includes a signal amplitude detector and a digital-to-analog converter. When the signal amplitude detector detects a low signal amplitude, a first current module in the digital-to-analog converter operates normally and a second current module in the digital-to-analog converter stops operating. In addition, when stopping operating, the second current module is in a state of a third bias voltage and a fourth bias voltage that are generated by a second bias circuit. When the amplitude detector detects a high signal amplitude subsequently, the second current module resumes normal operation. After operating normally, the second current module switches back to a first bias voltage and a second bias voltage that are generated by a first bias circuit. This reduces a nonlinearity problem caused before a second current module resumes normal operation.

Abstract: Systems and methods for data reduction including organizing data of an event stream into a file access table concurrently with receiving the event stream, the data including independent features and dependent features. A frequent pattern tree (FP-Tree) is built including nodes corresponding to the dependent features according to a frequency of occurrence of the dependent features relative to the independent features. Each single path in the FP-Tree is merged into a special node corresponding to segments of dependent features to produce a reduced FP-Tree. All path combinations in the reduced FP-Tree are identified. A compressible file access template (CFAT) is generated corresponding to each of the path combinations. The data of the event stream is compressed with the CFATs to reduce the dependent features to special events representing the dependent features.
