摘要
提出了一种基于FPGA的小波变换核的设计方案;介绍了小波变换的工作原理及其FPGA实现方式,利用FIR滤波器组实现了小波变换的Mallat算法,通过采用自顶向下的设计思想,使用Verilog语言进行了设计,在QuartusII及ModelSim下进行了编译和仿真。并最终将设计进行参数化,实现IP核的参数化。经验证系统工作灵敏、可靠,完全满足实时性的要求。
The paper proposes a design scheme for wavelet transform kernels based on FPGA. The working principle of the wavelet transform and its FPGA implementation is introduced. FIR filter banks are used to realize Mallat algorithm of the wavelet transform. With top-down design simulation are made under QuartuslI specific IP cores. The research results requirements. philosophy and Verilog language, the compilation and and ModelSim. The design is finally show that the system is sensitive and parameterized, for implementation in reliable, which can satisfy real-time
