A mature 32-bits POSIX OS for Intel and Motorola CPUs, new features added yearly: latest ISDN communication technology, Flash file systems, Java support, OCXen for Visual C++, Delphi and Visual Basic applications, and Internet server facilities. By Locamation Industrial Computer Products.

A secure, no royalty, for high reliability embedded systems; hardware memory protection to isolate and protect it and user tasks from incorrect operation by errors or tampering; object-oriented design allows verification of data security/integrity, communications, individual components, and whole system; strict adherence to provable resource requirements. ?? Green Hills Software, Inc.

A small (12-64k), standards-based, low cost, no royalty, commercial realtime OS; POSIX, ITRON/uITRON programming interfaces, GNU compiler support, source code provided; supports CPUs: Altera Nios, ARM, Hitachi SuperH. Free downloads: KROS demos, documentation, updates. By Shugyo Design Technologies, Inc.

Realtime kernel for embedded uses, follows Minimal Real-Time POSIX.13 subset. Most code is Ada, but some C, assembly. Hardware access via Abstract Hardware Interface (HAL). Runs in cross development environment: PC Linux Host, bare 386 PC Target, Ethernet LAN link. [Open Source, GPL]

A POSIX real-time operating system for x86/Pentium based systems. By Modcomp, Inc.

One-user, general purpose OS built on a protected memory, POSIX threads RT kernel; full kernel, device drivers, file systems, and network protocols runs in about 200 K RAM; now runs on x86 CPUs but designed for easy portability. [Open source, GPL]

Dynamic configurable kernel architecture to support hard/soft/non realtime use with interchangeable scheduling algorithms: fully modular in scheduling policies, aperiodic servers, concurrency control protocols; all not modular in most traditional OSs. Derived from HARTIK: HArd Real TIme Kernel. [Open Source, GPL]
