QNX is a commercial Unix-like real-time operating system, aimed primarily at the embedded systems market. The system is designed for use in cars, industrial control, medical devices, and other embedded systems.
QNX was originally developed in the early 1980s by Canadian company Quantum Software Systems, later renamed QNX Software Systems. The original team of developers was purchased by BlackBerry in 2010, who then continued development of the operating system.
QNX is a microkernel architecture operating system, meaning that the core functions of the operating system are implemented as separate processes that communicate with each other through a message-passing interface. This modular design makes it easier to develop and debug individual components, and also allows them to be replaced or upgraded without affecting the rest of the system.
The QNX Neutrino RTOS is the standard operating system used on all BlackBerry smartphones, including older generations of the Curve line. QNX also provides an operating system for BlackBerry PlayBook tablet computers.
The company has developed a free version of Neutrino 6 which supports ARM devices like Raspberry Pi and Freescale i.MX6 processors. The software does not support some features found in its commercial counterparts, such as App World integration or advanced camera APIs.
