摘要：

In order to achieve higher compression performance the amendment called Fidelity Range Extension (FRExt) was added to the H.264 Advanced Video Coding (AVC) standard which uses both 4x4 and 8x8 integer discrete cosine transform (DCT) adaptively in the high profiles. This led to additional complexity of the initial version of the H.264/AVC encoder which had substantially high computational complexity. In this paper we propose a new algorithm which reduces the computational complexity for software implementation of horizontal 8x8 Integer DCT by more than 25 percent. Simulation results indicate 22 percent reduction in the computation time by using the proposed algorithm.
