基于Simulink HDL Coder的跳频通信系统设计与实现
|
摘要
针对目前FPGA程序开发中模型开发方式应用较少的现状,基于simulink模型设计了跳频通信系统,利用simulink HDL Coder将跳频通信系统simulink仿真模型转换为HDL代码,在ISE中编译生成bit文件后加载到FPGA芯片之中,在FPGA信号处理板上实现了话音的实时通信。对基于simulink模型实现FPGA算法方法的优缺点进行了分析,对FPGA算法开发实现和simulink HDL Coder的推广应用具有一定的指导意义。
In the FPGA development,the model-based method is fewer applied. A frequency hopping communication system is designed based on simulink model. The simulink simulation model of frequency hopping communication system is transformed to HDL code by simulink HDL Coder. The bit file,which is built in ISE,is then loaded into FPGA. At last,real-time voice communication is realized on the FPGA signal processing board. The merits and demerits of this method to realize FPGA algorithm based on simulink model are analyzed,which is of a certain guiding value to the FPGA development and the extended application of simulink HDL Coder.
