Orthogonal wavelet transform is achieved in lifting steps in this paper.Derivation of the decomposition of traditional wavelet filters into lifting steps is given.The wavelet transform module is realized with dual-core computing in the FPGA hardware platform.Using single clock,the system meets the requirements of real-time processing without increasing the system design complexity and power consumption.Simulation shows that the system is stable and reliable.

Key words: biorthogonal wavelet;lifting wavelet transform;dual-core computing;hardware implementation
