The miniLZO decompression algorithm is a lightweight lossless decompression algorithm,which is widely used in network transmission.The high-speed cache scheme and the decompression scheme based on the state machine are designed in this paper by making full use of the parallelism of the FPGA to implement the miniLZO hardware decompression algorithm,so as to improve the decompression speed and reduce transmission delay.Engineering implementation of the hardware decompres-sion algorithm is performed on the XC7K325T FPGA chip of Xilinx Company.The test results show that the maximum through-put of the algorithm can reach 164 MB/s,and the hardware decompression scheme has fast speed,complete function,and is easy to be transplanted,which has a strong engineering practicability.
