摘　　要：随着嵌入式系统的发展与不断分化,很多领域如工业控制、机器人、视频图像系统等对嵌入式系统的要求越来越高,这不仅需要良好的功能扩展性和维护性,还需要保证专有任务的特性(如实时性等)。基于多核处理器的非对称嵌入式系统是解决这些问题的重要发展方向。根据处理器各核心地位是否相同,多核处理器可以划分为同构和异构两种结构。基于同构或者异构多核处理器均可以实现非对称嵌入式系统,从硬件或者软件层面将多核处理器的核心进行划分,分别运行不同的任务,使得嵌入式系统可以兼顾良好的功能扩展性和实时性。文中总结并对比了基于多核处理器的非对称嵌入式系统的研究现状,同时归纳了其在科研和工程领域的应用,最后研究了基于多核处理器的非对称嵌入式系统未来可能的发展方向。With the development and continuous differentiation of embedded systems,many fields such as industrial control,robotics,video and image systems,etc.have higher and higher requirements for embedded systems,which not only require good functional scalability and maintainability,but also need to ensure the real-time performance.Asymmetric embedded system based on multi-core processors is an important development direction to solve these problems.According to whether there is a primary and secondary distinction between processor cores,multi-core processors can be divided into two structures:homogeneous and heterogeneous.Asymmetric embedded systems can be realized based on both homogeneous and heterogeneous multi-core processors.The cores of multi-core processors are divided from the hardware or software level to run different tasks,so that the embedded system can balance good functional scalability and real-time performance.This paper summarizes and compares the research status of asymmetric embedded systems based on multi-core processors,and summarizes its applications in the fields of scientific research and engineering,and finally this paper studies the possible future development directions of asymmetric embedded systems based on multi-core processors.
