  2. 2. 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.
  3. 3. 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.
  4. 4.  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.
  5. 5. 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.
  6. 6. 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
  7. 7.  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
  8. 8. 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)
  9. 9. 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
  10. 10. 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.
