* Question
| What are the advantages and disadvantages of embedded real-time operating systems? |
* Answer
| The development of real-time applications in an embedded real-time operating system environment makes the design and expansion of the program easy, and new functions can be added without major changes. By dividing the application program into several independent task modules, the design process of the application program is more simplified; moreover, events with strict real-time requirements are processed quickly and reliably. Through effective system services, the embedded real-time operating system makes better use of system resources. However, the use of embedded real-time operating systems also requires additional ROM/RAM overhead, 2% to 5% of the additional CPU load and the cost of the core. |
