Description
Do most embedded projects need an RTOS? It's a good question. The answer lies in the very nature of embedded devices. Devices that, in many cases, are manufactured in the thousands, or millions, of units. Devices where even a $1 reduction in per-unit hardware costs can save the manufacturer a small fortune.
Savings aside, the services provided by an RTOS make many computing problems easier to solve, particularly when multiple activities compete for a system's resources. Consider, for instance, a system where users expect (or need) immediate response to input. With an RTOS, a developer can guarantee that operations initiated by the user will execute in preference to other system activities, unless a more important activity (for instance, an operation that helps protect the user's safety) must execute first.
But when exactly do you need realtime? Join Alan Zhang, Field Application Engineer at QNX Software Systems, for a web seminar where he discusses what is realtime, what makes a realtime system and when it's needed. He provides insights into the realtime design considerations taken from years in the embedded industry and explores some of the critical elements of realtime computing:
- scheduling
- priority inversion
- interrupt handling
- reliability
Estimated length: 1 hour, including Q & A.
Who should attend:This one-hour seminar with a short Q&A will be of great interest to embedded software development managers, architects, and developers
