航空电子系统中应用多核处理器的挑战分析

摘要

As a class of embedded systems, the computers of avionics is a hard real - time, high predictable and safety critical systems. For this reason, there are some additional challenges in using of multi - core processors in avionics. This paper analysis the reason why challenges taking place on the hardware/software architecture of multi- core processors, and point out the problem should be solved in using of multi -core processors in avionics.%作为嵌入式计算的一种,航空电子系统中的处理器具有强实时性、高确定生、高安全性的特征.因此,同其他嵌入式系统相比,在航空电子系统中应用多核处理嚣面临更多的挑战.针对多核处理器基本的软硬件架构,对挑战产生的原因进行了简要的分析,指出了在航空电子系统中应用多核处理器需要解决的问题.
