摘要:

应用提升方法实现了双正交小波变换。给出了应用因式分解法,将传统小波滤波器分解为基本提升步骤的推导。采用双运算核在FPGA硬件平台上实现小波变换模块。采用单一时钟,在不增加系统设计复杂性和功耗的情况下,使得系统达到实时处理的要求。系统通过仿真验证,工作稳定可靠。

Abstract:

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
