摘要

针对常规弹制导中导航传感信息采集、解算、通信的实时性问题

提出利用直接存储器访问（DMA）与传统信息处理方法相结合的方式实现常规弹多路传感信息的实时处理。分析了常规弹制导对传感信息处理技术的要求

并根据要求设计硬件电路。介绍了传统方式下传感信息处理的工作原理和在DMA方式下传感信息处理的工作原理。设计软件

并进行实验验证。实验结果表明:DMA与传统信息处理方法相结合的方式相对于传统方式的信息采集、解算、通信

其速度能够提高到3倍

满足常规弹导航信息处理的实时性要求。

Abstract

Aiming at the real-time problem of collection

calculation and communication of information of navigation sensing in conventional ammunition

present that combine direct memory access（ DMA） with traditional processing method of information to timely handle multi-channel sensing information of conventional missile.Analyze general requirement of processing technology of sensing information in navigation of conventional ammunition

and design hardware circuit according to the requirement. Introduce working principle of sensing information processing in traditional way and in DMA way. Design software and proves it by experiments. The result of this experiment indicates that the rate of information collection

calculation and communication of combination of DMA with traditional information processing method can be up to 3 times rate of traditional method

and it can satisfy the real-time request for information processing in navigation of conventional ammunition.
