摘要：Discrete wavelet transform is applied of the stationary and non-stationary signal, it is used to speechsignal, audio and video signal. Distributed arithmetic (DA) is a general and effective technique to implementmultiplier-less filters and has been exploited in the past to implement the discrete wavelet transform as well. It’s foundthat DA requires ROM and size of ROM increases exponentially as the increase in number of inputs, which highlyincreases the complexity. In this paper, high speed area efficient 2-D discrete wavelet transform (DWT) using 9/7 filterbased Modified Distributed Arithmetic (MDA) Technique. MDA technique is applied the low and high pass filter ofthe discrete wavelet transform. MDA technique is consist of adder, shift register and free of multiplier. This design isimplementation in Xilinx software and verified resistor transfer level (RTL) and waveform.
