RTLinux (RealTime Linux) is a small POSIX 1003.13/PSE51-compatible hard realtime operating system that runs Linux as its lowest priority ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ thread. It is somewhat like a single POSIX process sitting on a bare machine. Linux runs as the lowest priority thread of the RTLinux kernel, and it is always pre-emptible. RTLinux realtime applications consist of realtime threads and signal handlers that run in the RT environment, and processes that run in Linux user space. The RTLinux programming model is that anything that has strict timing requirements should be written as threads or signal handlers (interrupt handlers), and whatever does not need hard realtime should go into Linux. This allows us to keep the RT side small, deterministic and as fast as the hardware will permit, while still drawing on Linux for sophisticated services and applications. The basic mechanism that makes RTLinux work is protected under U.S. Patent 5,995,745 and is freely licensed to RTLinux users for commercial and non-commercial purposes as described below. RTLinux is distributed by Finite State Machine Labs, Inc. (FSMLabs). FSMLabs can be found on the Internet at www.fsmlabs.com. _________________________________________________________________ >===== End cut [rtl] =====< -- Svyatoslav <absolute_sh@mail.ru> [Registered Linux user #219421] --- QDed/Linux * Origin: AbSolute Soft&Hard (2:464/8088.100) Вернуться к списку тем, сортированных по: возрастание даты уменьшение даты тема автор
