ILAFM2016 Discrete Wavelet Transform Based on Coextensive Distributive Computation on FPGA Sowmya K B a , Dr.Jose Alex Mathew b a Assistant Professor,ECE Dept.,RVCE Bengaluru 560059, India b Professor and Head,ECE Dept.,SCEM Mangaluru 575007,India Abstract Subband coding has recently emerged as the leading standardization candidate in audio/video/image compression, echo cancellation, radar, image analysis, communications, medical imaging etc. Due to this, Discrete Wavelet Transform has gained much attention in memory efficient technique for handling large amounts of data. The implicit overlapping and variable-length basis functions from wavelets produce smoother and more pleasant reconstructions. Data compression, bit rate reduction is done by implementing memory efficient Discrete Wavelet Transform based on Coextensive Distributive Computation on FPGA. In this work Low complexity DWT Architecture which utilizes the Look-Up Table, using Shift register FPGA structure is developed to develop a filter bank without multiplier which is the important components in a DWT structure. This results in better space usage and reduction in the area size. Filter bank construction is done using DB-4 Daubechies 9/7 wavelets. This paper presents a consistent performance, good operating speed and area efficient DWT processor along with best utilization of resources available on target FPGA. The proposed Discrete Wavelet Transform System is implemented on Xilinx xc2vp30-7- ff896 Field Programmable Gate Array with highest operating frequency of 141.055MHz. © 2017 Elsevier Ltd.
