Abstract: The proposed DWT architecture for Image Compression targets the high-Speed processing improvement of DWT algorithm as compared to the existing architectures. It mainly includes line buffers, PIPO and lifting blocks. The methodology of using lifting scheme was to make architecture in a non-separable fashion and also to compute DWT algorithm at different resolutions. The RTL design will be coded via Verilog & synthesized using Xilinx ISE and vivardo tools, targeted on Spartan-6. The proposed architecture is scalable which can be parameterized for any size N(32,64,128,…..512). By the performance observation in the proposed architecture in terms of operating frequency for 128X128 image is 322.316 MHz implemented on spartan6 (xc6vhx565t-2ff1923) of FPGA board whereas it was seen in other architectures the maximum operating frequency was 254 MHz.
