Abstract

Abstract

The wavelet transform is a very effective mathematical tools for many fields such as signal processing and image coding, which is implemented by program in most cases. This paper presents a novel architecture suitable with CPLD chip for one- dimension DWT decomposition based on the relationship between wavelet transform and filter banks by rearranging the data in the processing of convolution and downsample by two. It possesses some practicable value with certain speed and decreased resources.
