Description As a -based OS, QNX is based on the idea of running most of the in the form of a number of small tasks, known as Resource Managers. This differs from the more traditional, in which the operating system kernel is a single very large program composed of a huge number of 'parts' with special abilities. In the case of QNX, the use of a microkernel allows users (developers) to turn off any functionality they do not require without having to change the OS itself; instead, those services will simply not run.

New Release of Empress Ultra Embedded Database For QNX® Neutrino® RTOS 6.4.0 is Here Beltsville, MD, March 3, 2009 - Software, developer of the EMPRESS Embedded Database, has just released the Empress Ultra Embedded Database V10.20 for the QNX Neutrino RTOS 6.4.0.
The system is quite small, with earlier versions fitting on a single 1.44. QNX Neutrino (2001) has been to a number of platforms and now runs on practically any modern CPU that is used in the embedded market. This includes the, family, and the closely inter-related family of, and CPUs.
QNX offers a license for non-commercial and academic users. The designed by BlackBerry uses as the primary operating system. Devices from BlackBerry running the operating system are also based on QNX.
It is commonly used in car infotainment systems with many major car makers offering variants that include an embedded QNX architecture. History and, both students at the in 1980, took a course in real-time operating systems, in which the students constructed a basic real-time microkernel and user programs. Both were convinced there was a commercial need for such a system, and moved to the high-tech planned community, to start Quantum Software Systems that year. In 1982, the first version of QUNIX was released for the.
In 1984 Quantum Software Systems renamed QUNIX to QNX in an effort to avoid any trademark infringement challenges. One of the first widespread uses of the QNX real-time OS (RTOS) was in the non-embedded world when it was selected as the operating system for the education system's own computer design, the. Over the years QNX was used mostly for 'larger' projects, as its 44k kernel was too large to fit inside the single-chip computers of the era.
The system garnered a reputation for reliability and found itself in use running machinery in a number of industrial applications. In the late-1980s, Quantum realized that the market was rapidly moving towards the model and decided to rewrite the kernel to be much more compatible at a low level. The result was QNX 4. During this time, while working as an intern, along with Robin Burgener (a full-time employee at the time), developed a new windowing system. This patented concept was developed into the embeddable named the QNX Photon microGUI. QNX also provided a version of the. Toward the end of the 1990s, the company (now called QNX Software Systems) began work on a new version of QNX, designed from the ground up to be capable, and to support all current and any new POSIX APIs that could be anticipated while still retaining the microkernel architecture.
This resulted in QNX Neutrino, released in 2001. Along with the Neutrino kernel, QNX Software Systems became a founding member of the consortium. The company released a suite of Eclipse plug-ins packaged with the Eclipse workbench in 2002 under the name QNX Momentics Tool Suite. In 2004, the company announced it had been sold to. Prior to this acquisition, QNX software was already widely used in the automotive industry for systems. Since the purchase by Harman, QNX software has been designed into over 200 different makes and models — not only in telematics systems but in infotainment and navigation units as well. The QNX CAR Application Platform is running in over 20 million vehicles as of mid-2011.
The company has since released several products including the QNX Aviage Multimedia Suite, the QNX Aviage Acoustic Processing Suite and the QNX HMI Suite. 's (ultra high availability IOS) built about 2004–2005, in it 32-bits version is based on QNX software, as is introduced in 2006. In September 2007, QNX Software Systems announced the availability of some of its source code. On April 9, 2010, announced they would acquire QNX Software Systems from Harman International Industries.
On the same day, QNX source code access was restricted from the public and hobbyists. In September 2010, the company announced a, the, and a new operating system based on QNX to run on the tablet. On October 18, 2011, Research In Motion announced 'BBX' which was later renamed to in December 2011. Blackberry 10 devices build upon the BlackBerry PlayBook QNX based operating system for touch devices, but adapt the user interface for smartphones using the based Cascades Native User-Interface framework.
At the Geneva Motor Show, Apple demonstrated which provides an -like user interface to head units in compatible vehicles. Once configured by the automaker, QNX can be programmed to handoff its display and certain functionality to an Apple CarPlay device. On December 11, 2014, stated the company would be replacing with QNX. In January 2017, QNX announced the upcoming release of its SDP 7.0, with support for Intel and ARM 32- and 64-bit platforms, and support for C14; it was released in March 2017. Technology The QNX kernel (procnto) contains only, redirection and timers. Everything else runs as a user process, including a special process known as proc which performs process creation and by operating in conjunction with the. This is made possible by two key mechanisms — subroutine-call type interprocess communication, and a which can load an image containing not only the kernel but any desired collection of user programs and shared libraries.
There are no in the kernel. The network stack is based on code. Along with its support for its own, native, device drivers, QNX supports its legacy, io-net manager server, and the network drivers ported from NetBSD. QNX interprocess communication consists of sending a message from one process to another and waiting for a reply. This is a single operation, called MsgSend. The message is copied, by the kernelfrom the address space of the sending process to that of the receiving process.
If the receiving process is waiting for the message, control of the CPU is transferred at the same time, without a pass through the CPU scheduler. Thus, sending a message to another process and waiting for a reply does not result in 'losing one's turn' for the CPU. This tight integration between message passing and CPU scheduling is one of the key mechanisms that makes QNX message passing broadly usable. Most and interprocess communication mechanisms lack this tight integration, although a implementation of QNX-type messaging for Linux.
Mishandling of this subtle issue is a primary reason for the disappointing performance of some other microkernel systems such as early versions of. The recipient process need not be on the same physical machine.
All I/O operations, file system operations, and network operations were meant to work through this mechanism, and the data transferred was copied during message passing. Later versions of QNX reduce the number of separate processes and integrate the network stack and other function blocks into single applications for performance reasons. Message handling is prioritized by priority. Since I/O requests are performed using message passing, high priority threads receive I/O service before low priority threads, an essential feature in a system. The boot loader is the other key component of the minimal microkernel system.
Because user programs can be built into the boot image, the set of device drivers and support libraries needed for startup need not be, and are not, in the kernel. Even such functions as program loading are not in the kernel, but instead are in shared user-space libraries loaded as part of the boot image. It is possible to put an entire boot image into, which is used for diskless embedded systems. Neutrino supports and, called bound multiprocessing (BMP) in QNX terminology. BMP is used to improve cache hitting and to ease the migration of non-SMP safe applications to multi-processor computers.
Neutrino supports strict priority-preemptive scheduling and (APS). APS guarantees minimum CPU percentages to selected groups of threads, even though others may have higher priority. The adaptive partition scheduler is still strictly priority-preemptive when the system is underloaded. It can also be configured to run a selected set of critical threads strictly, even when the system is overloaded. Transparent Distributed Processing Due to its architecture QNX is also a. And hold US patent 6,697,876 on 'Distributed kernel operating system' based on the QNX operating system's distributed processing features known commercially as Transparent Distributed Processing. This allows the QNX kernels on separate devices to access each other's system services using effectively the same communication mechanism as is used to access local services.
