Selecting an RTOS

Users searching for a real-time operating system (RTOS) for their project often get overwhelmed by the variety of commercial RTOSs available today. This variety nearly guarantees that an ideal system exists for you, but you finding it is a different question.

Embedded Computing Design published a helpful article about selecting an RTOS (this article was published a couple of years ago but the information is still relevant). An important note is that the article is written for selecting an RTOS for medical equipment requiring a high degree of safety and reliability. However, these are factors that should be considered for all embedded design applications, not just medical equipment.

One very important factor that the article does not discuss is RTOS cost. It becomes a complex decision when overall cost to develop the application is balanced against the direct cost of purchasing an RTOS. One needs to consider the initial cost to purchase the RTOS, per CPU license cost, associated third-party library cost with potential to save by reducing development and maintenance costs.

Check out the article and tell me what you think. I'll include your thoughts in a future newsletter.
