| Popis: |
A new implementation of a flexible discrete cosine transform (DCT) chip is presented. The DCT chip is suitable for transforming real-time video images using 16-point*16-point subframes. Some special features of distributed arithmetic and an application-specific pipelined RAM memory are used to obtain a high-performance architecture. A full system for 2-D 16-point*16-point transforms is integrated on a single chip using a 2- mu m CMOS technology. The choice of a DCT algorithm, the architecture, and the implementation are examined. > |
