Approximation Method for High Speed Multiplier-Less Dwt Architecture
Mrs. Geetha K · IOSR Journal of Electronics and Communication Engineering · 2012
This paper presents a VLSI design approach for a high speed and real time Discrete Wavelet Transform computing.The hardware requirement is a major concern in the computation of discrete wavelet transform.There are many multiplier-less architecture for DWT for reducing the hardware requirement.But it is observed that the approximation method for constant multiplier implementation in DWT can increases the speed and reduces the hardware requirement for the computation of Discrete Wavelet Transform.
