![]() Hence the task would be in sleeping position until the RTOS will wake up. Usually, there is an API that follows you to say “In 50ms wake me up”. If there is a 1ms system clock, then you have to complete the task in 50ms. To perform the time sensitive operation the RTOS will provide some sort of system clocks. There are some systems which support the more priority level and multiple tasks have some priorities. In generally 256 priority levels are used and each task has a unique priority level. The preemptive scheduling involves in the priority time-dependent time allocation. In this scheduling, each process is assigned a fixed time slot and the process needs to complete its execution or else the task loses its flow and data generation. In this type of scheduling, the task will run until the execution is completed Round Robin Scheduling Three techniques are modified to schedule the task, there are following with their description. In this state, if it doesn’t have the enough resources to run, then it is sent to blocked state. In the firm real-time, an operating system has certain time constraints, they are not strict and it may cause undesired effects.Examples of this operating system are a visual inspection in industrial automation. Some examples of this operating system are air bag control in cars, anti-lock brake, and engine control system etc. The predicted deadlines will react at a time t = 0. This is also a type of OS and it is predicted by a deadline. Soft Real-Time Operating System Hard Real-Time Operating System The examples of this operating system are the digital camera, mobile phones and online data etc. The critical time of this operating system is delayed to some extent. The soft real-time operating system is a type of OS and it does not contain constrained to extreme rules. The soft real-time operating system has certain deadlines, may be missed and they will take the action at a time t=0+. Types of RTOS Soft Real-Time Operating System ![]()
