Choosing the right embedded operating system is utterly crucial.A multitasking operating system has become essential to untangle the complex layers of software needed to drive the latest generation of interactive and networked embedded products. But before you pick the operating system software to be at the heart of your next design, take a look at the basic requirements and how they might affect overall product performance and the software development process. As embedded devices continue to increase in complexity, the software development task has become the largest element of the typical project budget. Graphical interfaces, network protocols, and just a few of the new requirements that design teams can find added on top of their custom application software.
