摘要： A server and a method for compressing data by a server are provided, which relate to the storage field and are used to resolve a prior-art problem that a compression ratio at which data in a data block is compressed by a server is relatively low. The method includes: parsing, by a server, an information block in a data block, to obtain a file type of data in the data block and a data sub-block that is included in the data block; determining a characteristic of data in the data sub-block according to the file type; selecting, according to the characteristic, a target compression algorithm that is used to compress the data in the data sub-block; and compressing the data in the data sub-block by using the target compression algorithm. Embodiments of the present invention are used to compress data.

摘要： Configurable compression and decompression of waveform data in a multi-core processing environment improves the efficiency of data transfer between cores and conserves data storage resources. In waveform data processing systems, input, intermediate, and output waveform data are often exchanged between cores and between cores and off-chip memory. At each core, a single configurable compressor and a single configurable decompressor can be configured to compress and to decompress integer or floating-point waveform data. At the memory controller, a configurable compressor compresses integer or floating-point waveform data for transfer to off-chip memory in compressed packets and a configurable decompressor decompresses compressed packets received from the off-chip memory. Compression reduces the memory or storage required to retain waveform data in a semiconductor or magnetic memory. Compression reduces both the latency and the bandwidth required to exchange waveform data. This abstract does not limit the scope of the invention as described in the claims.

摘要： A method for data compression includes reading first data representing sensor data capture, compressing the data with a lossless algorithm, transmitting the compressed data as a reference frame, reading subsequent data, calculating a delta between the first data and the subsequent data, compressing the data delta, and determining if the compression ratio of the compressed data delta is within a predetermined tolerance threshold. If the compression ratio is within the threshold, transmitting the compressed data delta frame, and repeating the calculating, compressing, and determining steps for subsequent data; Else if the compression ratio is not within the threshold, compressing the current subsequent data and transmitting the result as an updated reference frame. Then repeating the calculating, compressing, and determining steps for subsequent data. A system and a non-transitory computer-readable medium for implementing the method are also disclosed.

摘要： The present disclosure is directed dynamic compression/decompression (codec) configuration. In general, a device may include a codec configuration module to determine a configuration for use by the codec based on configuration criteria. The configuration criteria may include, for example, data characteristic information, system condition information and user expectation information. The configuration information may be used to select a codec configuration from one or more available codec configurations. For example, a benchmark module also in the device may determine the available codec configurations. After a codec configuration has been selected, it may be set in the codec. It may also be possible for the codec configuration module to monitor for changes in device operation (e.g., changes in the configuration criteria) and to update the codec configuration based on the monitored changes.

摘要： A size comparison unit 19 reports, to an access control unit 20, the size of a piece of compressed data having the smallest size from among pieces of compressed data generated via compression processing units 14A to 14D compressing blocks 12a, an algorithm name representing a compression processing unit 14 that has generated the piece of compressed data having the smallest size, and the like. Upon receipt of the report, the access control unit 20 selects a piece of compressed data to be written in a tape medium 30 and reports, to a statistical information processing unit 21, an algorithm name representing a compression processing unit 14 that has generated this selected piece of compressed data. The statistical information processing unit 21 extracts, from the reported algorithm name, a regularity present in a result of the selection of compressed data and, in accordance with this extracted regularity, specifies and stops a compression processing unit 14 to be stopped. As a result, it is possible to ensure the generation of optimum compressed data and to limit the power consumption more effectively by stopping the compression processing unit 14.
