Since 1980, manufacturers have relied on QNX realtime OS(RTOS) technology to power their mission-critical applications— everything from medical instruments and Internetrouters to in-car infotainment devices, 9-1-1 call centers,nuclear-monitoring systems, and military communications.Small or large, simple or distributed, these systems share an unmatched reputation for operating 24 hours a day,365 days a year, nonstop.

Build self-healing systemsTime-tested and field-proven, the QNX Neutrino® RTOS is built on a true microkernel architecture. Under QNXNeutrino, every driver, application, protocol stack, and filesystem runs outside the kernel, in the safety of memory-protected user space. Virtually any component can fail andbe automatically restarted without affecting other componentsor the kernel. No other commercial RTOS provides such a high level of fault containment and recovery.

Inherently modular, QNX Neutrino lets you dynamicallyupgrade modules, introduce new features, or deploy bug fixes — without costly downtime or system outages.

Scale large or smallDesign systems with a uni- or multiprocessor architecture,take advantage of the QNX Neutrino inherent multi-core capability and leverage built-in transparent distributed processing to create large, highly fault-tolerant systems.Whatever your design requirements, you can use the sameRTOS, tools, APIs, and source code for all your projects.The result? Longer product life cycles, shorter developmenttime, and a significant return on investment.

Maximize software investmentsEngineered to the POSIX standard (1003.1-2001 POSIX.1),QNX Neutrino gives you the power to port legacy and open-source UNIX, Linux, and Internet code with just a simple recompile. With standard APIs, you can reuseapplication code, avoid costly delays and shorten yourlearning curve — accelerating development cycles andreducing time to market.

In addition, QNX Neutrino provides pre-integrated, out-of-the-box support for a wide range of networkingprotocols, flash file systems, and a built-in high availability solution.

Operating system

Maximize securityUse adaptive partitioning to guarantee system resources foryour applications. Build secure, reliable embedded systemswithout compromising realtime performance and flexibility.To achieve the highest level of performance, adaptive partitioning allows applications to use all available CPUcycles under normal operating conditions. During overloadconditions, adaptive partitioning enforces hard resourceguarantees, ensuring applications receive their budgetedshare of resources.

Choose your hardwareJump-start development on your selected platform with QNX Neutrino support for a broad range of x86,PowerPC, ARM, SH-4 and MIPS platforms. Simplify driver development for custom hardware, using the QNX Neutrino resource manager framework, which unlike conventional drivers, runs in memory-protected user space.

Foundry27This community portal for QNX software developersprovides source repositories, forums, blogs, wikis, and, inthe community spirit, a bazaar that lets developers sharesource code and binaries with one another.
