The present disclosure relates to system(s) and method(s) for real time compression of a data frame. The system receives the data frame comprising a set of symbols. Further, the system identifies frequency of each symbol, from the set of symbols. The system further sorts the symbols in descending order of frequency, associated with each symbols. Further, the system computes a compression gain associated with each predefined case type, a set of predefined case types. Furthermore, the system selects a target predefined case type, based on the comparison of the compression gain of each predefined case types. The system further assigns a compressed code to Most Frequent Symbols (MFS), in the data frame. The compressed code is assigned based on the target predefined case type. Further, the system generates a compressed frame, associated with the data frame. The compressed frame comprises a header and a sequence of compressed symbols.

A graph compression system includes a memory unit to store graph data, and an electronic hardware controller in signal communication with the memory unit. The electronic hardware controller determines a distribution of a set of vertices in a graph, and encodes each vertex included in the set of vertices as a variable length integer (VLI) that includes a variable number of bytes. The variable number of bytes of each vertex is based on the determined distribution. Accordingly, the memory unit stores each vertex having been encoded according to the distribution of the set of vertices in the graph.

Deterioration of compression throughput including a decompression check after data compression is suppressed. Provided is a storage system including an interface and a controller. The controller includes a compression circuit configured to generate compressed data by compressing received data received via the interface; and a decompression circuit configured to decompress the compressed data before storing the compressed data in a storage drive to confirm data consistency. The compression circuit sequentially executes a compression task of the received data, sequentially generates packets of the compressed data, and transfers the packets to the decompression circuit. The decompression circuit decompresses the received packet in parallel with the compression task.

The present invention discloses a waveform file processing method, storage medium, and device, wherein the method comprises a storage step, and such storage step comprises the following sub-steps: obtain a waveform file that comprises at least one waveform signal; assign a basic index value based on the waveform signal, and adopt the variable-length encoding method to, in a memory, encode the said waveform file as a resolvable serialized structure; when the memory consumed by the serialized structure reaches the threshold, trigger the compression and persistence for the current serialized structure, and obtain the waveform processing file. The present invention uses a unique organization mode to locally or remotely generate a waveform file of a specific format so that the efficiency of subsequent storage, reading, and debugging based on the waveform database file of the said format is significantly improved.

The inventor has conceived, and reduced to practice, a system and method for data compaction using that applies delta encoding methods to entropy encoding methods to improve data compaction of entropy encoding methods under certain conditions and when compacting data having certain characteristics. Delta encoding may be applied to entropy encoding methods to further compact data sets by reducing the number of sourceblocks included in a codebook to those most commonly encountered in data to be encoded and, where mismatches occur during encoding, using delta encoding of bit differences with existing sourceblocks in the codebook rather than adding new sourceblocks to the codebook.

Other embodiments are also possible.

Technologies for compressing data with multiple hash tables include a compute device. The compute device is to produce, for each of multiple string prefixes of different string prefix sizes, an associated hash. Each string prefix defines a set of consecutive symbols in a string that starts at a present position in an input stream of symbols. The compute device is also to write, to a different hash table for each string prefix size, a pointer to the present position in association with the associated hash. Each hash is usable as an index into the associated hash table to provide the present position of the string.

The syntax modeler may associate a first sequence of symbols with syntax elements. The buffer may store tables, each represented by a symbol in the first sequence, and each used to associate a respective symbol in a second sequence of symbols with encoded data. The decoder decodes the data into a bitstream using the second sequence retrieved from a table.
