SpletSystems that carry real-time tasks are known as real-time systems. Soft real-time tasks: The task can be rescheduled. Hard real-time tasks: The tasks need to be performed within a certain time period. In this system, the scheduler is considered the most important component. The scheduler aims to reduce the response time for each process. the barefoot writers clubSplet07. jul. 2024 · Real-time processing involves more than just a fast operating system. An RTOS enables a deterministic response so your system acts predictably to events. The RTOS is designed so that at any time it can drop what it is doing to respond to an event. Task scheduling uses an algorithm that provably meets the deadlines of all tasks. the guitar and other machines
