VxWorks is a Unix -like Real-time Operating System made and sold by Wind River Systems of Alameda , California , USA. Like most RTOS es, VxWorks includes a Multitasking Kernel with pre-emptive Scheduling and fast Interrupt response, extensive Intertask Communication s and Synchronization facilities, and a File System . Newer versions of VxWorks now support PSOS system calls since Wind River now owns both RTOS es. Major distinguishing features of VxWorks include efficient POSIX -compliant Memory Management , Multiprocessor facilities, a Shell for user interface, symbolic and Source level Debugging capabilities, and performance monitoring. VxWorks is generally used in Embedded System s. 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 "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''. 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.
