In this brief, fast multiple inverse transform algorithms and their hardware sharing designs for 2 x 2, 4 x 4, and 8 x 8 inverse transforms in H.264/Advanced Video Coding and the 8 x 8 inverse transform in Audio Video Coding Standard, 4 x 4 and 8 x 8 inverse transforms in VC-1, and inverse discrete cosine transform in JPEG and MPEG-1/2/4 are developed with a low hardware cost, for multistandard decoding applications. By matrix factorizations and shift-and-addition computations, the proposed 1-D hardware sharing transform scheme is achieved without multiplications. The hardware cost of the proposed 1-D sharing architecture is smaller than that of the individual and separate designs. Through VLSI implementations with regular modularity, the 2-D transform with the proposed 1-D sharing architecture achieves multistandard real-time video decoding.
