摘要
多核操作系统是多核处理器广泛应用过程中的关键软件,而多核操作系统的引导程序又是多核操作系统正常运行的前提条件。针对T1020多核处理器,研究了多核操作系统的启动原理。介绍了T1020多核处理器的硬件资源。对多核操作系统的启动原理进行了研究,并详细介绍了主核和从核的启动流程。此外,在T1020处理器上实现了多核操作系统的引导程序并成功启动多核操作系统。在此基础上提出了两种测试多核操作系统成功启动的方法并给出了测试结果。
The multi-core operating system is the key software in the comprehensive adoption of the multi-core processor, and its bootstrap is a precondition for the normal operation.Based on the T1020 multi-core processor, the boot principles of a multi-core operating system are researched in this paper.The hardware resources of T1020 are firstly introduced, and then the boot principles of the multi-core operating system are researched.The boot-up process of the master-core and the slave-core are detailedly analyzed, and the bootstrap is implemented on T1020.The multi-core operating system is then successfully booted.Meanwhile, two methods for the multi-core operating system boot validation are proposed and the corresponding results are also demonstrated at the end of this paper.
