2.2Principle of the Software
2.2.1Features and functions of the real-time operating system
The system is a real-time multitask embedded system supported by a real-time operating
system. It is comprised of two parts: the real-time multitask operating system and system
application program, and it features as follows:
15. Real-time
16. Responding to asynchronous events
17. Responding to synchronous events
18. Interrupt management
19. Definite conversion time and interrupt delay time
20. Preemptive sequence arrangement
The operating system can realize the functions such as task conversion, task sequence
arrangement, communications among tasks, synchronization, mutual repulsion and
interrupt management, etc.
