基于DSP和AVR单片机的主从式双CPU导航计算机

Principal and Subordinate Navigation Computer with Dual CPU Based on DSP and AVR Single-chip Processor

介绍了一种小体积、低功耗、低价位的高性能导航计算机。此导航计算机由数字信号处理器(DSP)和AVR单片机两种CPU组成,DSP主要完成数据处理和制导算法运算,AVR单片机主要完成信息的采集和相关控制,两种CPU各自充分发挥自己的特点,协调地工作,能出色地完成导航计算机的功能。

This paper presents a new kind of navigation computer with the characteristics of small size, low power, low cost and high performance. This computer consist of DSP(Digital Signal Processing) and AVR single-chip processor, AVR single-chip processor has functions of data collected and I/O controlled etc; DSP is used to process the data. The AVR single-chip processor and DSP are designed on the same circuit diagram to realize the algorithm of integrated navigation system.
