A virtual device driver (VxD) is a software device driver that emulates hardware and other devices so that multiple applications running in protected mode can access hardware interrupt channels, hardware resources and memory without causing conflicts. The Vxd was superseded by the Windows Driver Model (WDM) and is now obsolete.
VxWorks is a proprietary and customizable real-time operating system (RTOS). VxWorks is designed for distributed computing on most central processing units (CPU) with embedded systems.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. VxWorks features include:
VxWorks is also applied in the spacecraft industry. Examples include:
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. Released in 1985, VxWorks was created and sold by Wind River Systems of Alameda, CA (USA).
