Identification and analysis of performance metrics for real time operating system

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.
