What it is
QNX Neutrino RTOS is a real-time operating system for embedded applications, including medical instruments, routers, telematics devices, process-control systems, and air-traffic-control systems. Its microkernel architecture keeps drivers, applications, protocol stacks, and file systems outside the kernel in memory-protected user space. If a component fails, the system can terminate it, reclaim its resources, and restart components without rebooting. Networking technologies include IPv4, IPv6, IPSec, FTP, HTTP, SSH, and Telnet. QNX Momentics is an Eclipse-based development environment with memory-protection diagnostics and system tracing. The RTOS supports multiprocessing, transparent distributed processing, and POSIX-based application portability, and lists support for MIPS, PowerPC, SH-4, ARM, StrongArm, XScale, and x86. QNX Software Center manages downloads of QNX Software Development Platform versions 7.x and 8.x. The product is paid, with runtime licensing options available by contacting QNX sales; there is no free plan, but a 30-day trial is offered for evaluation and exploratory development, not commercial development. QNX describes its Safe Kernel as certified to IEC 61508 Safety Integrity Level 3.
