QNX is a real-time embedded operating system designed for critical applications. It is a commercial Unix-like microkernel OS primarily used in industrial, medical, automotive, and telecommunications devices. QNX is highly reliable due to its microkernel architecture which isolates processes and protects against failures. It is also available in certified versions that have achieved safety and security standards for use in mission critical systems. QNX powers a wide range of systems that people interact with daily across various industries.

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.  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® RTOS

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.
