When asking questions about VxWorks, please specify the version of VxWorks you are using as well as the processor family, unless the question is of broader interest or impact.
VxWorks is used with a spectrum of hardware, including communications and network devices, testing and measuring devices, computer peripherals, automotive systems and consumer products.
VxWorks is compatible with a variety of CPUs, including: Microprocessor without Interlocked Pipeline Stages (MIPS), PowerPC, Intel i960, Scalable Processor Architecture (SPARC), SH-4, the x86 family, Advanced Risc Machine (ARM), StrongARM and xScale.
Features:
- Isolated user-mode applications
- Real-time processes
- Memory protection
- Efficient interprocessing, such as Transparent Inter-Process Communication (TIPC)
- Error handling
- Support for symmetric multiprocessing (SMP) and asymmetric multiprocessing (AMP)
- Binary, counting and mutual exclusion semaphores with priority inheritance
- Multitasking kernel with preemptive round-robin scheduling and fast interrupt response
- POSIX PSE52-certified compatibility with user-mode execution environment
- Distributed and local message queues
- VxSim simulators
- Virtualization profile.
- File systems, including Network File System (NFS), High Reliability File System (HRFS) and Disk Operating - System Filing System (DOSFS)
- Internet Protocol version 6 (IPv6) Networking Stack
Because code is written as required, VxWorks may be challenging for novice programmers. However, VxWorks uses less processing power than UNIX and runs at faster speeds because content is saved on a minimal basis.
Current Version: VxWorks 7
