Abstract: A compression system includes at least one acceleration device, a memory of the acceleration device stores a compression library, and the compression library includes one or more compression algorithms that support implementation of a lossless compression mode. The lossless compression mode is split into one or more fine-grained compression algorithms. Therefore, when obtaining any compression request, the compression system may select, based on an identifier that is carried in the compression request and that indicates a lossless compression mode, a compression algorithm corresponding to the lossless compression mode, thereby performing compression processing on data in the specified lossless compression mode by using the compression algorithm corresponding to the identifier.

Abstract: An image parallel compression method includes dividing data obtained after a discrete cosine transform (DCT) is performed on raw image data or data obtained after Huffman decoding is performed on image data of a joint photographic experts group (JPEG) format, or the like into several sub-blocks on a block basis, and then performing parallel operations such as intra-frame prediction, and arithmetic coding, to implement image parallel compression.

Abstract: Embodiments of the present invention disclose a data cache apparatus, and a data storage system and method. The data cache apparatus is coupled to a data processing device through a data interface. The data cache apparatus includes a controller and a memory coupled to the controller. The memory is configured to cache hot data in a hard disk that is connected to the data cache apparatus. The controller is configured to read data from or write data into the memory according to a data reading/writing request of the data processing device.
