It is very essential for large scaleembedded systems.
RTOS occupy little space from 10 KB to KB The main task of a RTOS is to manage. Real-Time Systems (cont.) –Hard real-time Tasks have to be performed on time Failure to meet deadlines is fatal Example: –Flight Control System.
Systems that interact predictably with events in the outside world; Examples: Widely used in all kinds of applications both on PCs and in embedded systems. Real-Time Operating Systems.

It determines the interrupt source and calls corresponding ISR.
Suppose a medium priority thread attempts to take a mutex owned by a low priority thread, but while the low priority thread's priority is elevated to medium by priority inheritance, a high priority thread becomes runnable and attempts to take another mutex already owned by the medium priority thread.

Semi-dynamic memory allocation Allocate statically and dispatch dynamically Explore memory requirements at design time. Saravanan Saran. Madhan N Kumar.
No notes for slide. When communication is from one process to a single other process, the IPC is said to be a unicast, e.
