基于FPGA的ⅡR数字滤波器协同仿真

FPGA Implementation of Digital Filter and Software/Hardware Co-simulation

文章引入FPGA来实现数字滤波器,在对一个4阶级联型ⅡR滤波器的系统仿真中,采用了两种仿真方法。与传统仿真方法相比,协同仿真打破了软硬件间的屏障,大大加快了系统的功能验证。实验结果表明:该验证方法具有结果直观,操作简单,效率高等优点。

FPGA was chosen to implement a digital filter. In the simulation of a fourth-order ⅡR filter, Two method were used. Compared with the traditional method, The co-simulation breaks the barrier between hardware and software, and also accelerates the function verification. The experiment results indicate that the approach of co-simulation has the advantages of obvious result, easy operation and high efficient in use.
