Abstract This paper presents a low-complex discrete wavelet packet transform (DWPT) architecture design for power constrained and cost sensitive healthcare applications. The multiplier-adder unit of the proposed multiplier-based designs of DWPT is replaced by the shift-add unit to reduce the area complexity of parallel structure. The proposed low-complexity multiplier-less design could be used an alternative to the existing multiplier-based design for hardware efficient realization of multi-level DWPT.
