WHAT IS QNX? Operating systems, development tools, and professional services for connected embedded systems QNX is a real time operating system designed for critical tasks. a commercial Unix-like real-time operating system, aimed primarily at the embedded systems market. Developed by Canadian company, QNX Software Systems, which was later acquired by Canadian BlackBerry-producer Research In Motion. The operating system based on the Neutrino microkernel QNX is based on the idea of running most of the OS in the form of a number of small tasks, known as servers allows users (developers) to turn off any functionality they do not require without having to change the OS itself; instead, those servers are simply not run. QNX is used in industrial, network, telecommunications, medical, and automotive devices.
QNX® NEUTRINO® RTOS The latest incarnation of the QNX realtime operating system, which has been powering mission-critical applications across the globe for three decades. is a full-featured and robust OS that scales down to meet the constrained resource requirements of realtime embedded systems. It is so reliable because it is a true microkernel operating system. It offers the embedded industry Â’s only field-proven, clean strategy for migrating from single-core to multi-core processing. It has a field-proven strategy for migrating from single- processor to multi-processor embedded environments Its unique bound multi-processing (BMP) technology takes the risk out of migration by enabling developers to decide exactly where every process and thread will run.
QNX Neutrino (2001) has been ported to a number of platforms and now runs on practically any modern CPU that is used in the embedded market. PowerPC-Performance Optimization With Enhanced RISC – Performance Computing x86 - refers to a family of instruction set architectures] based on the Intel 8086 CPU MIPS- Microprocessor without Interlocked Pipeline Stages SH-4 - SuperH is a 32-bit reduced instruction set computer ARM - Advanced RISC Machine StrongARM - a family of microprocessors that implemented the ARM V4 instruction set architecture(ISA). Xscale- a microprocessor core, is Intels and Marvells implementation of the ARMv5 architecture Under QNX Neutrino, every driver, protocol stack, filesystem and application runs in the safety of memory-protected user space, outside the kernel.
QNX NEUTRINO RTOS CERTIFIED PLUS The world’s first real-time operating system that provides both functional safety and security certifications RTOS is certified to IEC 61508 Safety Integrity Level 3 (SIL3) Common Criteria ISO/IEC 15408 Evaluation Assurance Level (EAL) 4+. It combines the benefits of the QNX® Neutrino® RTOS Safe Kernel and the QNX Neutrino RTOS Secure Kernel, its certification credentials combined with its microkernel architecture full POSIX-compliant API adaptive partitioning technology provide the ideal foundation for any system with functional safety and security requirements. It offers direct savings in manpower and development time and it streamlines product planning, system design, and product certification, thus shortening time to market.
QNX NEUTRINO RTOS SECURE KERNEL delivers the OS that companies creating aerospace, defense and security systems need to be able to meet the stringent safety and security requirements of mission-critical applications. provides different privilege levels for different applications, mediation to verify all accesses, and a mechanism for resource protection provides protective barriers between processes including networking and filesystems, which are typically within the kernel memory space in monolithic operating systems. is more secure than other commercial operating systems, because only a microkernel can provide proper isolation between all aspects of a system, including filesystems and networking stacks. This RTOS’s unique adaptive partitioning technology guarantees system resources for applications, while preventing rogue software from denying resources to other parts of the system
The QNX RTOS Secure Kernel is the first full-featured RTOS to Be certified under the common criteria standard Include symmetric multi-processing (SMP) support for multi- core processors Include the unique QNX adaptive partitioning technology in the certification
QNX NEUTRINO RTOS SAFE KERNEL certified by Sira to conform to IEC 61508 at Safety Integrity Level 3 (SIL 3) it provides a certified platform on which application developers can implement safety critical systems that must meet the most stringent functional safety requirements. The QNX Neutrino RTOS Safe Kernel contains: QNX Neutrino RTOS Safe Kernel certified to IEC 61508 SIL 3 IEC 61508 SIL 3 certificate (facsimile) Certification summary report QNX Neutrino RTOS Safe Kernel Safety Manual Installing and Using the QNX Neutrino RTOS Safe Kernel (user guide)
BENEFITS: The QNX Neutrino RTOS Safe Kernel incorporates many key characteristics required of an IEC 61508 SIL 3 certified system. These include: Design safe state — a well-defined state to which the kernel reverts when it encounters a situation that it cannot handle Isolation — between application processes, and between applications processes and the kernel itself Scheduling predictability — guaranteed processor resources according to thread priorities, assurance against "lazy" resource allocations, and scheduling analysis through techniques such as deadline and rate monotonic scheduling
QNX RTOS V4 the QNX® RTOS v4 is the predecessor to the QNX® Neutrino® RTOS it is still deployed and maintained in real-time and mission-critical projects around the world.
