Like most RTOSes, VxWorks includes a multitasking kernel with pre-emptive scheduling and fast interrupt response, extensive inter-process communications and synchronization facilities, and a file system. A Real Time Operating System or RTOS is an operating system that has been developed for real-time applications. ...

VxWorks is generally used in embedded systems. Unlike "native" systems such as Unix and Forth, VxWorks development is done on a "host" machine running Unix or Windows, cross-compiling target software to run on various "target" CPU architectures as well as on the "host" by means of VxSim.

History

The name VxWorks is believed to be a pun on the VRTX real-time operating system, at the time created by Ready Systems, now a Mentor Graphics product. In the early 1980s VRTX was a new product and did not work so well. It was 4KB in size and could not be fully used as an operating system. Wind River acquired the rights to resell VRTX with an extension named VxWorks which was workable (including for example a file system and an integrated development environment), so VxWorks most probably means VRTX now Works or VRTX that Works. For other uses, see Pun (disambiguation). ... Versatile Real-Time Executive (VRTX) is a real-time operating system nowadays developed and marketed by the company Mentor Graphics. ... This article does not cite any references or sources. ... It has been suggested that Crash counting be merged into this article or section. ... An integrated development environment (IDE), also known as integrated design environment and integrated debugging environment, is a programming environment that has been packaged as an application program,that assists computer programmers in developing software. ...


When Wind River anticipated that Ready Systems would cancel the contract, they developed their own kernel and put it in VRTX's place. The core functionality of VxWorks is similar to that of VRTX.


Tornado (v5 and older) or Workbench (v6 and newer)

Tornado is an integrated development environment (IDE) for software cross-development. Tornado consists of the following elements:

  • VxWorks target operating system
  • Application-building tools (cross-compiler and associated programs)
  • An integrated development environment (IDE) that facilitates managing and building projects, establishing host-target communication, and running, debugging, and monitoring VxWorks applications
  • VxSim simulator

Workbench replaced Tornado IDE in version 6 and newer. The Wind River Workbench is now built on Eclipse technology.[1] Eclipse is an open-source software framework written primarily in Java. ...
