QNX Wikipedia. QNX or is a commercial Unix likereal time operating system, aimed primarily at the embedded systems market. Dota Hotkey Garena. The product was originally developed in the early 1. Canadian company Quantum Software Systems, later renamed QNX Software Systems and ultimately acquired by Black. Berry in 2. 01. 0. QNX was one of the first commercially successful microkernel operating systemscitation needed and is used in a variety of devices including cars2 and mobile phones. DescriptioneditAs a microkernel based OS, QNX is based on the idea of running most of the operating systemkernel in the form of a number of small tasks, known as servers. This differs from the more traditional monolithic kernel, 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 servers will simply not run. The system is quite small, with earlier versions fitting on a single floppy disk. QNX Neutrino 2. CPU that is used in the embedded market. This includes the Power. PC, x. 86 family, MIPS, SH 4, and the closely inter related family of ARM, Strong. ARM and XScale CPUs. QNX offers a license for non commercial and academic users. The Black. Berry Play. Booktablet computer designed by Black. Berry uses a version of QNX as the primary operating system. Devices from Black.

HistoryeditGordon Bell and Dan Dodge, students at the University of Waterloo in 1. Both were convinced there was a commercial need for such a system, and moved to the high tech planned community Kanata, Ontario, to start Quantum Software Systems that year. In 1. 98. 2, the first version of QUNIX was released for the Intel 8. CPU. In 1. 98. 4 Quantum Software Systems renamed QUNIX to QNX in an effort to avoid any trademark infringement challenges. One of 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 Ontario education systems own computer design, the Unisys ICON.

Over the years QNX was used mostly for larger projects, as its 4. The system garnered a reputation for reliabilitycitation needed and found itself in use running machinery in a number of industrial applications. In the late 1. 98. Quantum realized that the market was rapidly moving towards the POSIX model and decided to rewrite the kernel to be much more compatible at a low level. The result was QNX 4. During this time Patrick Hayden, while working as an intern, along with Robin Burgener a full time employee at the time, developed a new windowing system. This patented5 concept was developed into the embeddable GUI named the QNX Photon micro. Discover why BlackBerry is the leading smartphone device solution.

QNX also provided a version of the X Window System. Toward the end of the 1. QNX Software Systems began work on a new version of QNX, designed from the ground up to be SMP capable, and to support all current POSIXAPIs and any new POSIX APIs that could be anticipated while still retaining the microkernel architecture. This resulted in QNX Neutrino, released in 2. Along with the Neutrino kernel, QNX Software Systems became a founding member of the Eclipse consortium.

QNX Momentics Tool Suite. In 2. 00. 4, the company announced it had been sold to Harman International Industries. Prior to this acquisition, QNX software was already widely used in the automotive industry for telematics systems. Since the purchase by Harman, QNX software has been designed into over 2. The QNX CAR Application Platform is running in over 2. The company has since released several middleware products including the QNX Aviage Multimedia Suite, the QNX Aviage Acoustic Processing Suite and the QNX HMI Suite. Ciscos IOS XR ultra high availability IOS built about 2. QNX software,8 as is IOS Software Modularity introduced in 2. In September 2. 00. QNX Software Systems announced the availability of some of its source code. On April 9, 2. 01. Research In Motion 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 2. 01. Black. Berry Play. Book, and a new operating system Black. Berry Tablet OS based on QNX to run on the tablet. On October 1. 8, 2. Research In Motion announced BBX1. Black.

Book QNX based operating system for touch devices, but adapt the user interface for smartphones using the Qt based Cascades Native User Interface framework. At the Geneva Motor Show, Apple demonstrated Car. Play which provides an i. OS 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 Car. Play device. 1. 61. On December 1. 1, 2. Ford Motor Company stated the company would be replacing Microsoft Auto with QNX. In January 2. 01. QNX announced the upcoming release of its SDP 7. Intel and ARM 3. 2 and 6. C1. 4 it was released in March 2. TechnologyeditThe QNX kernel contains only CPU scheduling, interprocess communication, interrupt redirection and timers. Everything else runs as a user process, including a special process known as proc which performs process creation and memory management by operating in conjunction with the microkernel. This is made possible by two key mechanisms subroutine call type interprocess communication, and a boot loader which can load an image containing not only the kernel but any desired collection of user programs and shared libraries. There are no device drivers in the kernel. The network stack is based on Net. BSD code. 2. 0 Along with its support for its own, native, device drivers, QNX supports its legacy, io net manager server, and the network drivers ported from Net. BSD. 2. 1QNX interprocess communication consists of sending a message from one process to another and waiting for a reply. This is a single operation, called Msg. Send. The message is copied, by the kernel,citation needed from 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 ones 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 Unix and Linux interprocess communication mechanisms lack this tight integration, although a user space implementation of QNX type messaging for Linux does exist. Mishandling of this subtle issue is a primary reason for the disappointing performance of some other microkernel systems such as early versions of Mach. All IO operations, file system operations, and network operations were meant to work through this mechanism, and the data transferred was copied during message passing.
