【摘要】 实时操作系统的调度策略是影响系统实时性和稳定性的一个重要因素,通过对抢占调度和分时调度的研究,设计了一个可分级抢占和分时调度的实时操作系统。用抢占调度方式来保证系统的实时性,用分时调度来减少进程饥饿现象的发生,提高系统的稳定性,更易于使用。更多还原

【Abstract】 real-time operating system’s scheduling strategy is an important factor that can affects system’s performance. The system designed in this paper is a multi-level preemptive and round-robin scheduling operating system.It uses preemption to ensure the system’s real-time performance and uses round-robin method to reduce procedure starvation makes the system more stable and easy to use.更多还原
