Summary:A unified 2-D IDCT architecture for multi-standard video codecs is proposed in this paper. The architecture is based on row-column decomposition method. A unified 4-state pipelined architecture is employed to implement the 1-D transform. Parallel register array is used to realize the transpose operation. The proposed architecture has a throughput of 3.2 pixels/cycle. Experiment results show that the proposed design achieves HDTV 1080i video processing requirement when operated at 30 MHz.
