Abstract: According to the framework of wavelet transform, a fully reconfigurable multi-purpose lifting kernel on FPGA was presented. From transform characteristics and reconfiguration requirement, with a bottom-up approach in design architecture, every lifting step can be represented by programmable parameters, which can guarantee lifting scheme reconfigurability. In addition, the architecture of lifting wavelet transform kernel was given. Different result was obtained through adjusting parameters in logical synthesis. Simulations illustrated that this lifting wavelet transform architecture possesses strong processing ability and low power consumption in real time image processing.

Key words: image processing, lifting scheme, FPGA, reconfigure, synthesis
