摘要
论述了采用定点数字信号处理(DSP)芯片TMS320C5402实现快速傅里叶变换(FFT)。采用了汇编语言实现FFT算法。实验结果验证了汇编语言适合实现复杂算法,也验证了实现算法的正确性,表明了利用DSP控制器特有的反序间接寻址FFT的实现是很方便的,且实时性非常好。
This paper introduces the Fast Fourier Transform （FFT） implementation in fixed - point DSP TMS320C5402. FFT algorithms are implemented by assemble language. The result verifies that assemble/anguage is more suitable for implementing the complicated algorithms, validates the correctness of FFT algorithms, indicates that the implementation of FFT with DSP＇s antitone indirect addressing is very convenient, the real time performance is also very good.
