A 2-D discrete wavelet transform hardware design based on multiplier design based architecture is presented in this paper. We have proposed based on arithmetic for low complexity and efficient implementation of 2-D discrete wavelet transform. The multiplier design based technique has been applied to reduce the number of delay. This paper provides the clearcut idea in about the application of 8-multiplier and 6adder in one, two & three level of architecture This architecture is suitable for high

With this architecture the speed of the 2-D discrete wavelet transform is increased. It has 100% hardware utilization efficiency KEYWORDS: 2-D Discrete wavelet transform (DWT), one level multiplier based design, two level multiplier based design, three level multiplier based design, multiplier based design scheme, Xilinx simulation.
