As reported on their home page:
ICARU_FB can run IEC 61499 standard on 8-bit microcontrollers and 32-bit computers.
The main requirements of the standard as portability, interoperability and configurability are our focus.
Currently ICARU_FB can run on an Arduino ATmega2560 or Windows operating system.
