Design
VxWorks is designed for use in embedded systems.
Some of the features of the current OS are:
- Multitasking kernel with preemptive and round-robin scheduling and fast interrupt response
- Native 64-bit operating system (only one 64-bit architecture supported: x86-64). Data model: LP64.
- User-mode applications ("Real-Time Processes", or RTP) isolated from other user-mode applications as well as the kernel via memory protection mechanisms.
- SMP and AMP support
- Error handling framework
- Binary, counting, and mutual exclusion semaphores with priority inheritance
- Local and distributed message queues
- POSIX PSE52 certified conformity in user-mode execution environment
- File systems: High Reliability File System (HRFS), FAT-based file system (DOSFS), Network File System (NFS)
- IPv6 networking stack

Famous quotes containing the word design:
“The reason American cars don’t sell anymore is that they have forgotten how to design the American Dream. What does it matter if you buy a car today or six months from now, because cars are not beautiful. That’s why the American auto industry is in trouble: no design, no desire.”
—Karl Lagerfeld (b. 1938)
“For I choose that my remembrances of him should be pleasing, affecting, religious. I will love him as a glorified friend, after the free way of friendship, and not pay him a stiff sign of respect, as men do to those whom they fear. A passage read from his discourses, a moving provocation to works like his, any act or meeting which tends to awaken a pure thought, a flow of love, an original design of virtue, I call a worthy, a true commemoration.”
—Ralph Waldo Emerson (1803–1882)
“Teaching is the perpetual end and office of all things. Teaching, instruction is the main design that shines through the sky and earth.”
—Ralph Waldo Emerson (1803–1882)
