TMS320F2812 DSP的FFT运算和DCT实现
Realization of FFT algorithm and DCT based on TMS320F2812 DSP
摘要
Abstract
The principle of Fast Fourier Transform （FFT） algorithm is described in this paper. FFT algorithm is realized by using of DSP. The system uses the internal ADC module and event- manager＇s general timer of TMS320F2812 DSP to achieve the real-time signal acquisition. ADC function of data collection is analyzed. The waveforms of input and output signals for FFT operations are displayed based on CCS debugging software. C language programming is used in environment of CCS, and FFT algorithm and DCT are realized.关键词
