| 摘 要： | 介绍了ADSL基本原理，指出单片DSP芯片组成的DSP系统已难适应ADSL系统的功能要求，而多片DSP芯片组成的并行处理系统，却增加了并行芯片之间的通信负担，实际仍不能解决问题。与此同时增加了系统的复杂性，使系统体积过大，难以应用于实际。本文提出了DSP／MCU组合方案，并结合工作实际给出了具体设计方案，结果表明DSP／MCU组合应用，系统简单易行，可以充分发挥DSP长于密集数字信号处理，MCU长于智能控制且编程相对容易的优点。

| Abstract: | ADSL fundamental principle was introduced in this paper,DSP system which is made up of single DSP chip is unfittable for the signal process requirement of ADSL ATU-R equipment,parallel DSP system leads to communication load and complexity,which is difficult for practual application.In this paper,DSP/MCU combination application was proposed,it shows that DSP/MCU combination application can ffully exert the merit of DSP which specializes in thick digital signal process and MCU which specializes in intelligent control and is easily programmed. |
