Real-time operating systems

Evidence Srl has been founded in 2002 by Paolo Gai taking a cue from his PhD thesis on an innovative Real-Time Operating System (RTOS) for multi-core platforms. In his work, Dr. Gai presented for the first time ERIKA Enterprise, a RTOS ready for the multi-core revolution and specifically designed for the automotive market.

Nowadays, ERIKA Enterprise is the first free of charge, royalty-free, OSEK-certified RTOS adopted by several companies to optimize their product cost and to maintain a high-level quality of service. Originally designed for automotive applications, it is now used also in household appliances, motor controls, battery management, sensor networks and for model based design.


As a result of our experience, we can now provide to our customers the following services:

  • ERIKA Enterprise porting on custom boards and/or application development. This OS allows to introduce open-source also for microcontroller and can be the base of new dual-OS systems (see the Linux Foundation webinar for more details)
  • FreeRTOS porting on custom boards and/or application development: FreeRTOS is one of the most used RTOS on the world, for this reason Evidence decided to provide high professional services based on this operating system. 
  • RTAI or Xenomai solutions: Linux is a widely diffused operating system, but it cannot be used in real-time applications. In the recent past Evidence Srl, together with several collaborators, participated in the development of a Linux Kernel Real-Time patch (SCHED_DEADLINE) acquiring experience and skills on Real-Time Linux solutions, like RTAI and Xenomai. We are now able to provide high-quality services to all of our customers, porting solutions based on other operating systems to Linux, optimizing product cost and a high-level technical assistance.  
  • VxWorks solutions: in these years we assisted many customers in their applications based on VxWorks, providing not only application development but also a professional technical support. For these reasons many customers expert in design and manufacturing of automatic machines, in avionics and in automotive contacted us to speed up the time-to-market and rapidly overcome technical barriers.
