Introduction
- Real-Time OS defined
- Real-Time OS Characteristics
- Examples of Real-Time Operating Systems
- Applications
3
Real-Time OS Definition
- Real-Time operating system is
- one whose correctness involves both the logical
correctness of the outputs and their timeliness.
- Practical Example
4
Real-Time OS Definition
- Hard Real-Time OS
- Firm Real-Time OS
- Soft Real-Time OS
5
Real-Time OS Characteristics
- Must handle multiple threads
- Must be able to prioritize tasks
- Must be able to schedule based on priorities
- Produce results in predictable timeframe
