摘要
本文介绍了用于对某型号飞行器飞控试验中用到的飞控数据处理器的设计思想和方法,该处理器用于对飞控计算机进行程序装载和参数记录。本数据处理器采用模块化设计,基于ATMEGA128单片机采用高速422接口进行实时数据通讯,采用Flash存储器实现了1G字节大容量存储;利用USB2.0接口完成10M字节/秒的高速数据读取。文章给出了单片机的程序装载和FLASH存储时序的详细设计和实现。
The data processor designed in the paper is used on aeroplane control computer for loading program and record parameters, which needs to transmit and receive large volume data at very high speed by serial port. Modularization design is adopted in the data processor, which can realize real-time data communication through ATMEGA128,accomplish 1GB storage capability by using flash memories and read data from processor at speed of 10MB/S via USB port.Design and realization of the program loading and flash storage are introduced in the paper in detail.
