BeRTOS: Free Embedded RTOS

  1. 1. Real Time Embedded OS Develer S.r.l.
  2. 2. Agenda “  Why Open Source software  Discover BeRTOS  Advantages for Business BeRTOS is a real-time system designed to build applications  BeRTOS in short for embedded systems  License  BeRTOS in use  10 reasons to ...  Questions?
  3. 3. Why Open Source Software  Lock­in avoidance  NO license costs  Decrease maintenance costs  Economical advantages
  4. 4. Lock­in avoidance No technological 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. 5. No license costs There are 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. 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.
  7. 7. Economical advantages Closed RTOS - License costs - Support costs Renewal - Maintenance contracts Contracts Fee - Annual cost increase Supplier Supplier License Support Maintenance - No license costs - No support cost - No maintenance cost BeRTOS - No cost increase No Fee Community Community License Support Maintenance
  8. 8. Discover BeRTOS  BeRTOS is easy  Supported platforms   Not only kernel!  Performance: Memory Footprint, Overhead  Competitors  BeRTOS is different
  9. 9. BeRTOS is easy ...   ... to Install  Thanks to the Wizard and the SDK you can be ready in a few minutes on  Windows.  ... to Use The graphical configuration Wizard is available on multiple platforms (Win, Mac  and Linux) and it's integrated with a certified IDE (CodeLite)  ... to Maintain The public BeRTOS repository is managed by the community, which provides  updates, ports and bugfix.
  10. 10. Supported platforms BeRTOS supports the most common microprocessor platforms (ARM and AVR). It's also possible to port it to any other platform. ARM7 AVR ATMega8 AT91SAM7S64 ATMega32 AT91SAM7S128 ATMega64 AT91SAM7S256 ATMega103 AT91SAM7X128 ATMega128 AT91SAM7X256 ATMega168 AT91SAM7X512 ATMega1281
  11. 11. Not only Kernel Modules Process BattFS ­ FAT ­ hashTable Monitor dynamic memory allocator FIFO ­ Lists ­ Kernel Kernel ADC API ­ Buzzer Dataflash ­ I2C EEPROM USB to parallel Keyboard ­ Graphic LCD DC Motor with PID On/Off Alphanumeric LCD Semaphores MPCdigital potentiometer NTC – TRIAC ­ PWM API I2C port expander Message Serial API ­ TC520 ADC Queues Thermostat ­ System timer API Stepper motor w/ramps Watchdog ­ ...  Signals
  12. 12. Kernel Performance BeRTOS performances are remarkable, it can be compared with commercial  versions of many RTOS (or more famous RTOS). A few KB 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
  13. 13. BeRTOS vs FreeRTOS FreeRTOS BeRTOS Conclusions Maintainer 1 developer Community - Speed of Support/Bugfix/Needs Platforms - ARM7TDMI Yes Yes - BeRTOS allows quick ports to any - AVR Yes Yes custom platform - Other platforms Yes No Features - Graphical wizard No Yes - Quick installation and configuration on - Windows SDK No Yes Win, Mac and Linux systems - Debugging in IDE No Yes - Availability of development and - FAT filesystem No Yes debugging tools integrated with the - Log/Debug No Yes working environment - More features available Support - Community Yes Yes - Commercial Yes Yes - High quality technical support Licensing Modified GPL Modified GPL - Investments in software developments have competitive advantages without source code sharing
  14. 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.
  15. 15. BeRTOS for Business Fast Time to Market   Shorter development time  Reduced start­up cost  Focus on ideas  Immediate support  Stable and mature system  Re­usability = More opportunities
  16. 16. Fast Time to Market BeRTOS guarantees a fast 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. 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. Drivers Algorithms ADC handling Checksum and Hash Flash memories Xmodem protocol E2PROM RLE compression Keyboard management Full Hash Table Graphical displays Command History Stepper and DC motors Command parser Triac for power control Lists and FIFOs PWN/NTC Exception handling Thermostat
  18. 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:
  19. 19. Focus on ideas With BeRTOS you can 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:
  20. 20. Immediate support Support is available through a technical mailing list for developers: There are also special premium support packages which guarantee support  time, fixed cost ports, or ad hoc developments even on custom boards. Premium support minimizes the risks of delays, due to technical problems, for  your development team.
  21. 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:
  22. 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:
