Phoenix-RTOS is a

real-time operating system A real-time operating system (RTOS) is an operating system (OS) for real-time applications that processes data and events that have critically defined time constraints. An RTOS is distinct from a time-sharing operating system, such as Unix, which m ...

designed for Internet of Things appliances. The main goal of the system is to facilitate the creation of "Software Defined Solutions".

Phoenix-RTOS is the successor to the Phoenix

operating system An operating system (OS) is system software that manages computer hardware, software resources, and provides common services for computer programs. Time-sharing operating systems schedule tasks for efficient use of the system and may also i ...

Phoenix-RTOS 2.0

The decision to abandon the development of Phoenix and write the Phoenix-RTOS from scratch was taken by its creator in 2004. In 2010, the Phoenix Systems company was established, aiming to commercialize the system. Phoenix-RTOS 2.0 is based on a

monolithic kernel A monolithic kernel is an operating system architecture where the entire operating system is working in kernel space. The monolithic model differs from other operating system architectures (such as the microkernel architecture) in that it alone ...

HaaS modules

The Phoenix-RTOS can be equipped with HaaS (Hardware as a Software) modules that allow the implementation of rich devices functionality, e.g. modems. Existing HaaS modules include: # Phoenix-PRIME - software implementation of PRIME PLC standard certified in 2014. # Phoenix-G3 - a software implementation of the G3-PLC standard.

Implementations

In 2016, Energa-Operator (based in Poland) installed 6.6k Data Concentrator Units with balancing meter functionality in its network, based on the Phoenix-RTOS. License agreements to use the system in the mass production of smart meters have been signed.
