摘要
论述了用数字信号处理(DSP)芯片TMS320LF240x自带的模数转换模块(ADC)进行数据采集,并对采样结果进行了FFT变换,实验结果表明用DSP控制器特有的反序间接寻址使FFT的实现很容易,且实时性能很好。
This paper describes the high-speed data acquisition based on the ADC of TMS320LF240xDSP chip, and processes the sampling results with FFT transformation. The result indicates that realization of FFT with DSP own antitone indirect addressing is very easy, and the real-time behaviour is also good.
