QNX is a real-time operating system designed for critical embedded systems. It is a commercial Unix-like microkernel OS primarily used in industrial, medical, automotive, and telecommunications devices. Some key features of QNX include high reliability, determinism, small memory footprint, and ability to scale from single-core to multi-core processors. The latest version, QNX Neutrino RTOS, has various safety and security certifications making it suitable for applications with functional safety and security requirements.

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. 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.  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 Intel's and Marvell's
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. 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. 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.  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. 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. 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. 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.
