Abstract :
It is described that Fast Fourier Transform (FFT) implementation in floating-point DSP TMS320VC33. The result indicate that assemble language is more suitable for implementing the complicated algorithms than c language, validates the correctness of FFT algorithms, indicates that the implement of FFT with DSP own antitone indirect addressing is very convenient, the real-time performance is also very good, It satisfied the requirement of spectrum analysis in a vehicle Transient Fault Recorder in the field of harmonics analysis and vibration analysis.
