Abstract: In this paper, a new system including Discrete Wavelet Transform (DWT) and Entropy Coder (EC) is presented for JPEG2000 implementation. The system accomplishes a seamless connection between DWT and EC. To reach the goal, an EC-based DWT scheme is proposed, and a new EC architecture is designed that encodes three code-blocks concurrently. The system reduces the memory requirement significantly. Compared to the QCB-DWT scheme, more than 72 percent of memory is removed. And it is a high speed encoding system, able to encode 720*576 video more than 40 frames per second at 54MHz clock frequency.
