Abstract

The embodiment of the invention discloses a decompression method, device and system for an FPGA heterogeneous acceleration platform. The method comprises the following steps: receiving first data to be decompressed sent by a host side processor and storing the first data to be decompressed; calling a decompression algorithm implemented by an FPGA hardware circuit according to a start-up instruction and parameter information sent by the host side processor, and decompressing the first data to be decompressed based on the decompression algorithm to obtain decompressed data, wherein the parameter information contains data information corresponding to the first data to be decompressed and a compression relation table; and storing the decompressed data, and returning a completion signal to the host side processor to ensure that the host side processor receives the completion signal and then reads the decompressed data. According to the decompression method, device and system disclosed by the invention, the decompression speed can be increased during use, and the power consumption required during decompression can be reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of data processing, in particular to a decompression method, device and system based on an FPGA heterogeneous acceleration platform. Background technique [0002] In the era of cloud computing, the amount of transmitted data is increasing, and the transmission of massive data needs to occupy a large bandwidth, which seriously affects the performance of network transmission in cloud computing data centers. In order to improve the performance of the network output, it is necessary to use a lossless compression algorithm to compress the transmitted massive data, and it is also necessary to decompress the compressed files. In the process of mass data transmission, increasing the speed of data compression and / or increasing the speed of decompressing compressed data can improve the performance of network transmission.
