摘要
提出一种基于RTX+Windows+反射内存网的导引头实时系统仿真架构。通过RTX保证系统的实时性,在RTX下采用多线程并行方式降低信号处理时间;通过与Windows间的共享内存实现系统友好的人机交互;以反射内存卡为传输介质,保证数据传输的实时性。经过测试,该架构可以真实地仿真出导引头系统的整个工作过程,信号处理时间控制在ms级,数据传输速度超过800Mbit/s,线程切换时间与响应延时小于13μs。
A real-time system simulation architecture for seeker was proposed based on RTX+Windows+reflection memory network.This architecture guaranteed the real-time performance of the system through RTX,and reduced the signal processing time by adopting multi-threaded parallel mode under RTX.The shared memory between RTX and Windows realized the friendly human-machine interaction.The real-time data transmission was ensured by using reflection memory card as transmission medium.After testing,it is found that the architecture can simulate the whole working process of seeker system in real-time,controlling the signal processing time at the level of millisecond.The data transmission speed is over 800 Mbit/s and the thread switching time and response delay were less than 13μs.
