TMS320C80实现DIT快速傅利叶变换

Implementation of Radix--4 Decimation in Time Fast Fourier Transform (DIT FFT) Algorithm for the TMS320C80 DSP

随着现代社会的数字化，各种数字信号处理技术正在进入社会生活的各个领域中。数字信号处理器（ＤＳＰ）在将各种技术付诸实践方面起着巨大的作用，ＴＩ公司生产的ＴＭＳ３２０系列是目前最常用的数字信号处理芯片。本文中，我们采用了ＴＩ公司的性能优越的多处理器芯片 ＴＭＳ３２０Ｃ８０来实现数字信号处理技术中最基本、最常用的傅利叶交换。

Digital signal processing has almost affected every field of the society. In the hardware realization of the digital signal processing technique, all kinds of digital signal processor have played a important role. Especially DSPs which produced by Texas instruments is very popular. In this paper, we use the digital signal multiprocessor, i. e. TMS320c80, to realize Radix -- 4 fast Fourier transform (FFT) which is the most fundamental technique of digital signal processing.
