Entropy Coding Based On Code-Value Compact Memory Structure for AVS Video Coding Standard
Entropy coding based on k-th order Exp-Golomb (EGk) codes is a key part in the new AVS video coding standard issued by Audio Video Coding Standard Workgroup of China. An efficient design based on code-value compact memory structure (CVCMS) is proposed to reduce the computational complexity and memory requirement. Only 789 byte memory is required for variable length coding (VLC) tables in CVCMS, which is just about 5.92% compared with that of the reference software. Furthermore, code-value is stored in memory, which reduced the computational complexity of EGk coding. The simulation results show that the proposed entropy coding for AVS video coding standard reduces the computational cost by 26.48%
