FPGA Hardware Implementation of Optimized LZW Compression Algorithm
This article proposes a hardware implementation of the LZW compression algorithm based on FPGA to address the slow software implementation speed and excessive CPU resource consumption,which is not suitable for scenarios with real-time re-quirements.By determining the size of the dictionary and optimizing dictionary updates,search time and memory usage are reduced.The Kintex-7 series FPGA XC7K160T is used for hardware acceleration processing,greatly improving data compression speed and efficiency.Experimental results show that the hardware implementation achieves an average compression rate of 386 Mb/s,which is 9.66 times faster than software,and is superior to traditional software implementations of the LZW algorithm in terms of compression rate and real-time performance.
