Abstract

RTOS performance analysis is critical during the design and integration of embedded software to guarantee that application time constraints will be met at run time. To select an appropriate Operating System for an embedded system for a specific application, OS services needs to be analyzed. These OS services are identified by parameters to form Performance Metrics. The Performance Metrics selected include Context switching time, Preemption time, Interrupt Latency, Semaphore Shuffling time. In this research the Performance Metrics is analyzed in order to select right OS for the an embedded system for a specific application.

实时操作系统性能指标的识别和分析
在嵌入式软件的设计和集成过程中,RTOS性能分析对于保证在运行时满足应用程序的时间限制至关重要。要为特定应用程序的嵌入式系统选择合适的操作系统,需要分析操作系统服务。这些操作系统服务由参数标识,形成性能指标。选择的性能指标包括上下文切换时间,抢占时间,中断延迟,信号量变换时间。在本研究中,分析了性能指标,以便为特定应用的嵌入式系统选择合适的操作系统。
