High-throughput and low-complexity binary arithmetic decoder based on logarithmic domain

摘要

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