摘要
文中描述了一种针对快速傅里叶变换(FFT)嵌入式运算系统的设计,基于ST公司ARM架构的微控制器STM32F4,该控制器拥有强大的数据运算处理能力,在硬件架构以及数据、信号处理上做出了独特的设计。着重介绍了基于Cortex-M4的FFT软件实现,应用,以及数据采样,运算等一系列问题,最后明确了下一步的研究方向。
The article shows an embedded system designed for FFT algorithm. The hardware platform is based on the micro-controller STM32F4 with ARM core ＂Cortex-M4 ＂produced by ST Company. This micro-controller has strong ability to deal with complex signals and has special designs on its hardware architecture and digital signal processing. It mainly introduces the way to realize the FFT software algorithm based on the Cortex-M4 mico-controller and a series of key points about its application,sampling and calculating. Finally,it shows the way of future improvements.
