在未来的航空电子体系结构中,综合核心处理器(Integrated Core Processor,ICP)将成为整个航空电子系统的核心。本文首先对ICP进行了理论分析,提出了ICP建模的重点,然后采用面向对象、模块化的方法进行了ICP仿真软件的设计,建立了ICP仿真系统模型。软件的仿真核心基于离散事件仿真方法,采用双层任务调度算法,并结合航空电子系统分区管理的特点,模拟ICP系统对任务的处理过程。最后进行了实例仿真,对仿真结果进行分析,验证了模型的正确性。
In the future avionics architecture, the Integrated Core Processor (ICP) will be at the core of the entire avionics system. In this paper, the theoretical analysis of ICP is first made, and the emphasis of ICP modeling is put forward. Then the design of ICP simulation software is carried out by using the object-oriented and modular method, and the ICP simulation system model is established. The simulation core of the software is based on the discrete event simulation method and adopts the double-task scheduling algorithm. Based on the characteristics of the avionics system partitioning management, the simulation process of the ICP system on the tasks is simulated. Finally, an example simulation is carried out and the simulation results are analyzed to verify the correctness of the model.
