| 中文摘要: |
| 随着计算机系统与物理世界的结合越来越紧密，实时系统需要承担越来越复杂的运算任务.多核处理器的兴起为同时满足实时性约束和高性能这两方面的需求提供了可能.基于多核处理器的实时嵌入式系统的研究已成为近几年研究的热点.对现有的面向实时多核嵌入式系统的研究工作进行了综述，介绍了实时多核嵌入式系统的关键设计问题，从多核共享资源干扰及管理、多核实时调度、多核实时程序并行化、多核虚拟化技术、多核能耗管理和优化等几个方面对现有研究工作进行了分析和总结，并展望了实时多核系统领域进一步的研究方向. |
| 英文摘要: |
| As computer systems are more and more closely integrated into the physical world, real-time systems are required to perform more and more complex computation tasks. The development of multi-core processors makes it possible to fulfill the requirements of both real-time constraints and high computation demands. The research on real-time multicore system has attracted a lot of attention in recent years. This paper presents a survey on the research of real-time multicore system. The survey first introduces the main research problems and challenges. Then, a detailed review is provided covering the various topics, such as shared resource interference, real-time scheduling in multi-core system, parallel real-time software design, multicore virtualization, and power management under real-time constraints. Open issues and research directions are also identified in this survey. |
