LZW algorithm is one of the most famous dictionary-based compression and decompression algorithms. The main contribution of this paper is to present a hardware LZW decompression algorithm and to implement it in an FPGA. The experimental results show that one proposed module on Virtex-7 family FPGA XC7VX485T-2 runs up to 2.16 times faster than sequential LZW decompression on a single CPU. Since the proposed module is compactly designed and uses a few resources of the FPGA, we have succeeded to implement 150 the same modules which works in parallel on the FPGA. In other words, our implementation runs up to 264 times faster than a sequential implementation on a single CPU. |
