In this paper, two novel hardware architectures based on tabled asymmetric numeral systems decoding algorithm are proposed. In the proposed architectures the decoding throughput is highly dependent on the how much the data is compressed at encoding time. The synthesis results presented here show that the throughput of the parallel architecture can reach up 200 MB/s. The benchmarks show that the parallel architecture that runs on Xilinx Kintex FPGA provides higher throughout in comparison with the same algorithm running on Core i3 CPU.
