Vxworks

The meaning of «vxworks»

VxWorks is a real-time operating system (RTOS) developed as proprietary software by Wind River Systems, a wholly owned subsidiary of TPG Capital, 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 AMD/Intel architecture, POWER architecture, ARM architectures[2] and RISC-V.[3] The RTOS can be used in multicore asymmetric multiprocessing (AMP), symmetric multiprocessing (SMP), and mixed modes[4] and multi-OS (via Type 1 hypervisor)[5] designs on 32- and 64-bit processors.[6]

VxWorks comes with the kernel, middleware, board support packages, Wind River Workbench development suite and complementary third-party software and hardware technologies. In its latest release, VxWorks 7, the RTOS has been re-engineered for modularity and upgradeability so the OS kernel is separate from middleware, applications and other packages.[7] Scalability, security, safety, connectivity, and graphics have been improved to address Internet of Things (IoT) needs.[8][9][10]

VxWorks started in the late 1980s as a set of enhancements to a simple RTOS called VRTX[11] sold by Ready Systems (becoming a Mentor Graphics product in 1995).[12] 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.[13]

Published in 2003 with a Wind River copyright, "Real-Time Concepts for Embedded Systems"[14] describes the development environment, runtime setting, and system call families of the RTOS. Written by Wind River employees with a foreword by Jerry Fiddler, chairman and co-founder of Wind River, the text book is an excellent tutorial on the RTOS. (It does not, however, replace Wind River documentation as might be needed by practicing engineers.)

VxWorks supports Intel architecture, Power architecture, and ARM architectures.[2] The RTOS can be used in multi-core asymmetric multiprocessing (AMP), symmetric multiprocessing (SMP), and mixed modes[6] and multi-OS (via Type 1 hypervisor)[5] designs on 32- and 64-bit processors.

The VxWorks consists of a set of runtime components and development tools. The run time components are an operating system (UP and SMP; 32- and 64-bit), software for applications support (file system, core network stack, USB stack and inter-process communications) and hardware support (architecture adapter, processor support library, device driver library and board support packages).[6] VxWorks core development tools are compilers such as Diab, GNU, and Intel C++ Compiler (ICC)) and its build and configuration tools. The system also includes productivity tools such as its Workbench development suite and Intel tools and development support tools for asset tracking and host support.[6]
