An optimized implementation of intra predictor for AVS decoder was proposed according to the algorithms in the AVS spec-ification. Two-Dimensional (2-D) filters were used in the design, and intra prediction for each block could be finished in 8 cycles. Data selection complexity was reduced by data shifting between registers. Lots of multiplexers were saved. The synthesis result indi-cated that the design could be used for real-time decoding of high-resohition videos.
