The engine executes an efficient implementation ofthe Feig algorithm. Performance evaluation concludes that the proposed architecture can adequately deal with real bineMPEG-1 IDCT requirement together with achievable cost reduction when compared with dedicated hardware approach[4]. In addition, it can be observed that the proposed architecture can also be utilized to deal with Other functionalities such as variable length MPEG-1 bitstream decoding, inverse one dimensional (1D) DCT (Discrete CosineTransform) audio decoding.展开更多
