A High-Throughput and Low-Complexity Decoding Scheme based on Logarithmic Domain

This paper proposes a high-throughput and low-complexity decoder (D_LBAC) based on Logarithmic Binary Arithmetic Coding (LBAC). It can easily implement multiple symbols decoding. The proposed scheme does not use multiplication and division operations nor look up tables (LUTs). It has a simple algorithm structure and only requires additions and shift operations. Experimental results show that it has about 0.2–0.7 % bit-rate savings and can decode 3.5 symbols per cycle on average. The hardware implementation design described in this paper can achieve a high symbol processing capability and the lower hardware costs.
