- 4. Lockin avoidance Notechnological lock-in with respect to proprietary systems Many different companies can offer the same services on the market. The customer can change the source if the seller can't do or it's not interested in doing such modification. No mandatory binding with the supplier You can choose any supplier which satisfies your business demands. You can change business partner any time you want since the sources are shared. Open system An internal “expert” team can make any change to the source. You can easily train human resources thanks to the shared documentation. Quality and efficiency The developers commit themselves to code quality. Many developers improve the system thanks to free access to source code. It's often at the forefront of technology, it's well documented, stable and secure.
- 5. No license costs Thereare three main costs in a software project: - license purchasing, - program installation and customization, - internal costs due to resource organization. The cost for an open source based project is two thirds with respect to a project based on proprietary software. You don't pay the operating system, but only value added services such as human resources training or customized developments or ports on your custom boards.
- 6. Decrease maintenance costs It's built with modern technologies and paradigms Using standard technologies make it simpler to integrate the project with technologically different infrastructures. The community maintains it It's convenient to use open source software because maintenance is shared with the community, thus decreasing costs Integrated with your features Contributing your modifications means the community will maintain and keep up to date them with every new development for free.

- 12. Kernel Performance BeRTOS performances are remarkable, it can be compared with commercial versions of many RTOS (or more famous RTOS). A fewKB on flash with all kernel modules active (semaphore, signals, message queues) Linear RAM occupation with the number of processes Minimum stack: 200 bytes on 32-bit ARM, 100 bytes on 8-bit AVR Context-switching speed: 2.2 us on ARM @ 48 MHz From 25% to 30% faster than competitors

- 14. BeRTOS is different Code Beauty Every development on BeRTOS strictly follows the principles of code consistency and readability. The source code is completely commented to ease immediate understanding. Simplicity Every development on the BeRTOS system is implemented following the simplicity principle. This principle makes the system much more modular (it can work without kernel!) and more scalable in the requirements and performance. Reusability Applying reusability principles to BeRTOS code allowed to improve parameters such as occupied physical space and lower resource requirements for system usage. Security BeRTOS allows a completely static memory allocation, implicitly making more secure your developments and your embedded applications.

- 16. Fast Time to Market BeRTOS guarantees afast time to market, thanks to a complete feature set and easy-to-use development tools that contribute to cut down project's realization time. (Many modules and drivers are already built in)
- 17. Shorter development time The reduced necessity to develop customized solutions can save you many development hours, thanks to many drivers and algorithms already included into the libraries.

- 18. Reduced startup costs Develer reduces start-up costs, offering BeRTOS as free operating system even for: - closed source projects; - commercial projects. ● The total cost of ownership (TCO) is reduced thanks to: - the development technical community - the modified GPL license @Image by Tab.itha: http://www.flickr.com/photos/tab_itha/
- 19. Focus on ideas With BeRTOS youcan shift your economical focus from the tool (the required licenses) to the product (your application), as you don't need to buy a license @Image by Majed: http://www.flickr.com/photos/majedphoto/

- 21. Stable and mature system BeRTOS is constantly updated with new developments and patches which expand its features. The system is considered mature thanks to 8 years presence in Develer's embedded projects. Develer also provides ports and bugfix @Image by RyckyDavid: http://www.flickr.com/photos/cuppini/
- 22. Reusability = More opportunities Each component can be re-used in every other project, so you can quickly update or broaden your products by using existing code. This allows to: - release in short times a wider choice of embedded products; - be in the forefront to consolidate your position in the embedded software market. @Image by RyckyDavid: http://www.flickr.com/photos/cuppini/
