초록

This paper proposes an implementation of DCT (Discrete Cosine Transform) and IDCT (Inverse DCT) using a fast DCT algorithm with shift and addition operations instead of multiplications Based on the proposed algorithm, a new VLSI architecture for the DCT and the IDCT is proposed. It shows modularity , regularity and capability for multiprocessing. Its performance is also simulated by a simulation software, "Compass". The results of the simulation provide the quality of decompression images, the increase in processing speed, representing the superiority of the proposed architecture.
