摘要
根据设计要求,利用Matlab信号处理工具箱中的滤波器,可以很方便地设计出符合应用要求的未经量化的IIR滤波器,并进一步用VHDL语言加以描述,通过编译、功能仿真、综合和时序仿真之后就可以在FPGA上实现了。此设计扩展性好,在实际使用中,可适当修改外围参数改变滤波器的频率响应,根据不同的要求在不同规模的FPGA上加以实现。
The introduction of this paper is in height of the method of the high-step IIR digital adopting cascade structure of wave filter in realizing on FPGA . the wave filter of Matlab design of in signal handling tool case are used to design the IIR wave filter that does not be quantified in accordance with application requirement very conveniently, and it is further described with VHDL language, through compiling, function emulatation, synthesis and can be realized on FPGA after sequential emulatation. This desi...
