摘要
嵌入式应用中采用SMP(对称多处理)系统所面临的主要难题是多处理器内核之间的通信。对ARM11 MPCore处理器的多核间通信机制进行研究,并结合Linux-2.6.19对这一通信机制的具体实现作深入分析,并在RealView Emulation Baseboard上面进行相应的验证。实验结果表明,多核间通信机制可以使多线程之间的交互时间减小为原来的16.7%,从而提升并行计算系统的性能。
Inter-processor communication is a main problem in embedded applications adopting SMP （Symmetrical multi-processing） system. Based on the study of the inter-processor communication mechanism of ARM11 MPCore processor, in this article it analyzes the implementation of this mechanism in depth with linux-2. 6.19. The corresponding validation has been done on the RealView Emulation Baseboard. The result of the experiment indicates that the inter-processor communication mechanism can reduce the interactive time of muhithreading down to 16.7% of the original, sequentially this raises the performance of the parallel computation system.
