MENG Wei, JIN Long-xu, HAN Shuang-li. Design of VLSI Architecture of 2-D Lifting Wavelet and FPGA Verification[J]. , 2011,26(3): 404-408 DOI: 10.3788/YJYXS20112603.0404.
In order to save the resource and improve the speed of wavelet transform's hardware realization
an effective 2-dimension wavelet transform hardware structure has been proposed. This structure used parallel pipeline architecture
each layer of wavelet transform processed by parallel while pixels processed by pipeline. And the structure can improve the speed of wavelet transform
save the on-chip and external memory resource. It had been tested on Xilinx SPARTEN-3 series FPGA by processing large image with size 1 0242 048. Results showed the image processing speed could reach 80 Mpixel/s
meeting the real-time requirement.
