Optimization Design and Implementation of HD CABAC Decoder
摘要
Abstract
Aiming at the problem that the strong data dependency and low parallelism in Context-based Adaptive Binary Arithmetic Coding (CABAC), this paper proposes an optimized real time CABAC decoding architecture for H.264/AVC high profile in HD application. The architecture is based on the two-level storage structure and adopts syntax element prediction and merging strategies, optimizes the decoding decision processing and reuses the de-binarization circuits. Test results show that the architecture achieves a high performance with a low cost, and it is sufficient for HD application in FPGA.关键词
