Abstract

This paper presents a FPGA Implementation of wavelet-based CODEC, which can compress 2-dimensional image. For real-time processing, a scheduling method of input image data is proposed and a new structure of MAC(multiplier-accumulator) is proposed for wavelet transforms. Also this study proposes global pipelining structure of wavelet CODEC and efficient buffering method at interfaces between each module with different clock frequency.
