Abstract：In this paper,using a very long instruction word (VLIW) architecture view,the existing state of the art algorithms were compared with an algorithm that is tailored for VLIW architecture in the form of matrix.The architecture's character is further exploited to design a new fast inverse discrete cosine transform (IDCT) algorithm.Compared with existing algorithms,the new algorithm reduces the number of instruction cycles needed.Further,the register character of VLIW is used for merging motion compensation with IDCT (DCT) in the video codec process.This achieves 50% speed improvement.The concept is applicable for MPEG1/2/4 and H.264/AVC.
