摘要
为提高飞控软件研制效率,研制基于真实DSP的软件实时动态仿真系统,该系统采用与弹载计算机相同的DSP板作为仿真对象,通过中断驱动方式,使嵌入式软件运行;通过1553B接口板,RS-422接口板和双口RAM实现与外界的通讯;在仿真计算机上搭建模拟真实外部环境的数学模型对目标进行仿真,从而达到从功能上验证嵌入式软件的目的;最后给出该系统在实际中的应用。
A real-time dynamic simulation system based on real DSP is developed to improve the efficiency of flight control software design.The DSP board,which is the same as the one loaded on bomb,is used as the target board of the system.The embedded software runs through the interrupt driving mode.Communication with outside is through 1553 interface,RS-422 interface and dual-port RAM.Mathematical models of external environment are built on simulation computer to test the embedded software functionally.Application in engineering is given at the end.
