Efficient one-dimensional forward and inverse discrete wavelet transformers

Abstract This paper describes the efficient one-dimensional forward and inverse discrete wavelet transformers with 5/3 filter. This design reuses the same registers for both low-pass and high-pass filtering in different time slots. It utilizes 33% less registers, 17% less logic elements, has 7% higher maximum operating frequency and 2% lower total power dissipation than state-of-the-art filters.
