  Discrete Wavelet Transform (DWT) becomes a main part of numerous signal and image processing applications. The lifting scheme has been developed recently as a flexible tool for constructing lossless bi-orthogonal wavelets. This study proposes efficient and high performance architecture for dual mode (forward and inverse) Integer Haar Lifting Wavelet Transform (IHLWT) core. The presented architecture minimizes the hardware area by proposing multipliers-free design. It performs IHLWT with only a single adder and subtractor which have reconfigurable input buses to perform forward or inverse transformations based on mode control signal. The proposed architecture has been implemented on Field Programmable Logic Array (FPGA). The design has been developed by using Hardware Description Language (HDL); this makes the design easily portable across FPGA devices from any vendor. The synthesis of the design showed that it has high operating-frequency and requires low hardware area and low power consumption for various Xilinx FPGA devices. The designed processor has been successfully implemented and tested on Xilinx Spartan6-SP601 Evaluation Board. The implemented hardware has been tested in real time by using many recording audio signals. All the implemented hardware results were identical 100% with IHLWT software results. This design is appropriate for applications require real time and low power consumption IHLWT processor such as wireless multimedia sensor networks.
