Realization of Rife method in FPGA based on system generator

在FPGA平台上应用System Generator工具实现了高精度频率估计Rife算法。不同于传统的基于HDL代码和IP核的设计方法,采用System Generator工具可以使复杂算法在FPGA中更快、更准确地实现。给出了Rife算法的描述和实现结构框图,并在System Generator和ISE环境中进行了仿真,验证了设计的正确性。

The high performance frequency estimation algorithm（Rife method） is established in FPGA by using System Genera- tor. Unlike traditional design method based on HDL code and IP core, using System Generator tool, the complex algorithms can be faster and more accurately implemented in the FPGA. The design methods of every main function module in the system are de- scribed. The simulation was both done in System Generator and ISE. Finally, the con＇ectness of the design is verified.
