Simulation Of Pre-Emptive Scheduling For Accuracy Improvement By Using RTOS

Now-a-days Hardware and Software are developing very high level. But with the increasing of SOC designs, Hardware dependent Software (HDS) become Critical. In Previous work they introduced abstract RTOS modeling, which exposes dynamic scheduling effects early in the system design. However, such models insufficiently capture preemption. But the accuracy of preemption depends on the granularity of the timings. So we cannot take accurate readings. For an accurately modeled interrupt response time, very fine-grained timing annotation is necessary. It contradicts the RTOS abstraction idea and is detrimental to simulationion idea and is detrimental to simulation
