VxWorks is a real-time operating system (RTOS) developed as proprietary software by Wind River of Alameda, California, US. First released in 1987, VxWorks is designed for use in embedded systems requiring real-time, deterministic performance and, in many cases, safety and security certification, for industries, such as aerospace and defense, medical devices, industrial equipment, robotics, energy, transportation, network infrastructure, automotive, and consumer electronics.[1] VxWorks supports Intel (x86, including the new Quark SoC,[2] and x86-64), MIPS, PowerPC, SH-4, and ARM architectures. The RTOS can be used in multicore asymmetric multiprocessing (AMP), symmetric multiprocessing (SMP), and mixed modes[3] and multi-OS (via Type 1 hypervisor) designs on 32- and 64-bit processors.[4] VxWorks comes with the kernel, middleware, board support packages, and Wind River Workbench development suite. Various complementary third-party software and hardware technologies are also available. In its latest release, VxWorks 7, the RTOS has been re-engineered for modularity and upgradeability so the OS kernel is seperate from middleware, applications and other packages. Scalability, security, safety, connectivity, and graphics have been improved to address Internet of Things (IoT) needs.[5][6][7]
History
VxWorks started in the early 1980s as a set of enhancements to a simple RTOS called VRTX[8] sold by Ready Systems (becoming a Mentor Graphics product in 1995).[9][10] At the time, VRTX had quality issues, was 4KB small in size, lacked critical features, and was generally not up to par as a full-blown RTOS. Wind River acquired rights to distribute VRTX and significantly enhanced it by adding, among other things, a file system and an integrated development environment. In 1987, anticipating the termination of its reseller contract by Ready Systems, Wind River developed its own kernel to replace VRTX within VxWorks.[11] The VxWorks name is believed to be a pun on VRTX ("VRTX that works"). Legend has it, that the company founders, Jerry Fiddler and Dave Wilner, first conceived of forming Wind River and creating VxWorks, while hiking in the Wind River mountains of Wyoming.[citation needed]
VxWorks key milestones:
- 1980s: (32-bit processing) – VxWorks adds support for 32-bit processors
- 1990s: (the Internet) – VxWorks 5 becomes the first RTOS with a networking stack
- 2000s: (multi-core) – VxWorks 6 supports SMP and adds derivative industry-specific platforms
- 2010s: (64-bit processing and the Internet of Things) – VxWorks adds support for 64-bit processing[4] and introduces VxWorks 7 for IoT.[12]
Platform overview
VxWorks supports Intel® (x86, including the new Quark SoC,[2] and x68-64), MIPS, PowerPC®, SH-4, and ARM® architectures. The RTOS can be used in multicore asymmetric multiprocessing (AMP), symmetric multiprocessing (SMP), and mixed modes[4] and multi-OS (via Type 1 hypervisor) designs on 32- and 64-bit processors.
The VxWorks Core Platform includes the following runtime components:
Runtime components:
- OS (UP and SMP; 32- and 64-bit)[4]
- Application support: file system; core network stack; USB stack; inter-process communications (IPC)
- Hardware support: architecture adaptor; processor support library; device driver library; BSPs
Development tools:
- Core tools: compilers (Diab, GNU, and Intel C++ Compiler (ICC)); build and& config tools
- Productivity tools: Workbench development suite; Intel tools
- Development support: host support; asset tracking
The platform is a modular, vendor-neutral, open system that separates the OS kernel from middleware, applications and other packages.[6] This separation enables easier integration and testing of new software.[12] An implementation of a layered source build system in VxWorks 7 allows multiple versions of any stack to be installed at the same time so developers can select which version of any feature set should go into the VxWorks kernel libraries.
Optional add-on Profiles add incremental functionality required for specific industries (such as medical, industrial, networking and consumer) or technology-related capabilities, such as its small footprint RTOS (Microkernel Profile) and a type 1 hypervisor (Virtualization Profile).[12][13]
Features
VxWorks is designed for use in embedded systems.
Some of the features of the OS are:
- Multitasking kernel with preemptive and round-robin scheduling and fast interrupt response
- File systems: High Reliability File System (HRFS), FAT-based file system (DOSFS), Network File System (NFS), and TFFS
- Native 64-bit operating system[14] (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, AMP and mixed mode multiprocessing support
- Error handling framework
- Bluetooth, USB, CAN protocols, Firewire IEEE 1394, BLE, L2CAP, Continua stack, health device profile
- Binary, counting, and mutual exclusion semaphores with priority inheritance
- Local and distributed message queues
- POSIX PSE52 certified conformity in user-mode execution environment[15]
- File systems: High Reliability File System (HRFS), FAT-based file system (DOSFS), Network File System (NFS)
- Dual-mode IPv6 networking stack with IPv6 Ready Logo certification
- Memory protection including real-time processes (RTPs), error detection and reporting, and IPC
- Multi-OS messaging using TIPC and Wind River multi-OS IPC
- Symbolic debugging
In March 2014, Wind River introduced VxWorks 7, which emphasizes scalability, security, safety, connectivity, and virtualization[7][12][16] The following lists some of the release 7 updates.[1][4][7][17]
- Layered build system supports independent layer updating

Hardware support
VxWorks has been ported to a number of platforms and now runs on practically any modern CPU that is used in the embedded market. This includes the Intel x86 family (including the Quark SoC),[2] MIPS, PowerPC (and BAE RAD), Freescale ColdFire, Intel i960, SPARC, Fujitsu FR-V, SH-4 and the closely related family of ARM, StrongARM and xScale CPUs. VxWorks provides a standard board support package (BSP) interface between all its supported hardware and the OS. Wind River’s BPS developer kit provides a common application programming interface (API) and a stable environment for real-time operating system development.
Development environment
As is common in embedded system development, cross-compiling is used with VxWorks. Development is done on a "host" system where an integrated development environment (IDE), including the editor, compiler toolchain, debugger, and emulator can be used. Software is then compiled to run on the "target" system. This allows the developer to work with powerful development tools while targeting more limited hardware. VxWorks uses the following host environments and target hardware architectures:[18]
Supported Host Environments
- Windows 8 / 7 / Vista (Business and Enterprise), SP 2 / XP Professional, SP 2 or 3
- Red Hat Enterprise Linux Workstation 5, Update 2 or 3, x86 (32-bit/64-bit) / 4, Update 6 or 8, x86 (32-bit)
- Red Hat Fedora 11, x86 (32-bit/64-bit) / 9, x86-64
- Novell SUSE Linux openSUSE 11.1, x86 (32-bit/64-bit) / 11.0, x86 (32-bit/64-bit)
- Novell SUSE Linux Enterprise Desktop 11.0, x86 (64-bit) / 10.2, x86 (32-bit/64-bit)
- Ubuntu Desktop 9.04, Update 4, x86 (32-bit/64-bit) / 8.04, Update 4, x86 (64-bit)
- Solaris 10 (with GTK), Update 11/06, SPARC 32-bit
Supported Target Architectures and Processor Families
The newly-released VxWorks 7 supports the following target architectures:
- ARM 11 / 11 MPCore / 9 / Cortex A9 MPCore / Cortex A8
- Intel Pentium family / Quark / Xeon / Xeon LV / Core / Core 2 Duo / Atom
- PowerPC 86xx, 8641d / 85xx, 8572 / 83xx / 74xx / 7xx / 60x / 44x / 40x / QorIQ P4080 / QorIQ P20xx
The Eclipse-based Workbench that comes with VxWorks is used to configure, analyze, optimize and de-bug a VxWorks-based system under development.[19] The Tornado IDE was used for VxWorks 5.x[20] and was replaced by the Eclipse-based Workbench IDE for VxWorks 6.x.[18] Workbench is also the IDE for the Wind River Linux[21], On-Chip Debugging[22] product lines. VxWorks 7 uses Wind River Workbench 4 VxWorks[23], and Wind River Diab Compiler product lines. VxWorks 7 uses Wind River Workbench 4 which updates to the Eclipse 4 base providing full third party plug-in support and usability improvements.
VxWorks 7 includes three compilers:[18] Diab Compiler, GNU, and the Intel C++ Compiler. Diab Compiler is the default C/C++ compiler for building VxWorks kernel, libraries, BSPs, and applications. It has been used for mission-critical systems for over 20 years. The GNU Compiler 4.8 is based on the Free Software Foundation (FSF) distribution of GCC and g++. Wind River has modified it to for use with VxWorks. The Intel C++ Compiler processes C and C++ source code to generate machine code for IA 32 or Intel 64 applications.
Wind River Simics[24] is a standalone simulation tool compatible with VxWorks. It simulates the full target system (hardware and software) to create a shared platform for software development. Multiple developers can share a complete virtual system and its entire state, including execution history. Simics enables early and continuous system integration and faster prototyping by utilizing virtual prototypes instead of physical prototypes.
