Design of an Area Efficient High-Speed Color FDWT Processor
Senthamaraikannan Raghunath, Syed Mahfuzul Aziz · 2006
A two dimensional discrete wavelet transform processor for color images is presented in this paper. Optimal hardware utilization with minimal CLB slice count and high frequency of operation is achieved in implementing a JPEG2000 standard integer lossless 5/3 filter. Lifting scheme is used to reduce hardware complexity. Image boundaries are handled using the symmetric extension property of the lifting scheme at no extra clock cycle. Synthesizing the proposed architecture for a Xilinx Virtex 2 FPGA, we achieve a maximum frequency of operation of 218.7 MHz utilizing only 478 CLB slices for any input color image of arbitrary size
