 QNX4Company Description:The QNX 4 realtime OS offers you all the advantages of a true microkernel. It's small, scalable, extensible, and fast.As a true microkernel OS, QNX starts with a lean core of highly reliable code. It's small enough for ROMable embedded applications, yet powerful enough to run a distributed network of several hundred processors. QNX is also easy to extend, giving you the ultimate in design flexibility. Use the multitude of modules QNX provides or extend the OS with your own modules. With QNX's robust protected-mode environment, you're always free to test your extensions and try new approaches. No matter what, your system stays up. And QNX is fast. With its low OS overhead and executive-class speed, QNX lets you deliver low-cost PC-based products that often outperform costly high-end systems. The QNX microkernel handles process creation, memory management, and timer control. QNX's unique approach to transparent distributed processing lets you launch processes across the QNX network, allowing for full inheritance of the environment, including open files, current directory, file descriptors, and user ID. The microkernel also includes POSIX.1 (certified) and many POSIX.1b realtime services, as well as high-speed diagnostic event tracing. Worldwide Headquarters:
