VLSI design and implementation of the entropy decoder for multi-format video decoding algorithms

The entropy decoder proposed in this paper was implemented in VLSI (65nm process). It supports video decoding algorithms for three most popular video standards, H.264, AVS and MPEG-2. The decoding modules of H.264, AVS and MPEG-2 have some shared components, which greatly reduces the cost of hardware resources. Verification results showed that when exploiting a 200MHz working frequency, the entropy decoder can achieve 1080p@30fps for H.264, AVS and MPEG-2. This paper mainly focuses on the following aspects: the entropy decoder architecture and H.264, AVS and MPEG-2 decoding modules implementation.
