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。
With the digitization of modern society, various digital signal processing technologies are entering various fields of social life. Digital signal processors (DSPs) play a huge role in putting various technologies into practice. The TMS320 family from TI is by far the most commonly used digital signal processing chip. In this article, we use TI’s superior multi-processor chip TMS320C80 to achieve the most basic and common Fourier switching in digital signal processing.
