摘要
按照小型、稳定、可靠的要求,设计了一种基于ADSP-218x芯片的DSP嵌入式系统,该系统是某红外型跟踪装置的重要组成部分,他能够实时完成6路A/D数据采样、数字滤波、与上位机通讯、D/A输出以及数字I/O控制等功能。讲述了该系统DSP芯片及其外围器件的选用,硬件电路与接口的设计以及嵌入式软件的结构、流程与开发方法。
According to the small type,stability and reliability,a kind of DSP embedded system based on ADSP -218x is designed. This embedded system is an important component of one IR seeker,it samples 6 channels A/D data, filter, communicats with the host machine,outputs 1 channel D/A data and controls the multi - channel digital I/O. It must finish all these work in real- time. This paper introduces the choice of chips,interface design,and the embedded soft design.
