Comparing to other entropy coding standard

CABAC(context adaptive binary arithmetic coding) has more significant enhancement in compression.However

its encoding/decoding efficiency is low due to calculation complexity and costs in memory access.To deal with the "bottleneck" problem in decoding process

the article proposes efficient hardware architecture for CABAC decoder

including a new memory access mode

an optimizing decoding core and four concatenating decoding engines.The experimental results show that the decoding efficiency is greatly increased by the hardware architecture.
