| Abstract: | A fast DCT transform based on model design was implemented.By optimizing arithmetic and using resource in effect,the pipelining architecture was developed,and the method can process data in real time.Using EDA tools to simulate logic and post-route,the result proved that the method was effective to achieve high speed and low resource. |
