VGA

 

Video Graphics Array

view

 

A view is a visual component within Workbench, typically used to navigate a hierarchy of information (such as the resources in your workspace). Only one view has focus (is active) at a time.

view port

 

The view port is the rectangular area, similar to the clip rectangle, in the default bitmap to which drawing operations are restricted. All drawing is performed relative to the view port.

VIP

 

VxWorks Image Project. A VIP provides build support, source code analysis, and other capabilities that simplify the creation, configuration, and building of a kernel image. A VIP is one of the primary means for configuring VxWorks (the other is the VSB project). To work with (configure and build) a VIP, you can use the Workbench development suite (IDE) or the vxprj command line development tool.

virtual board (VB)

 

A virtual target hardware configuration presented to a guest OS or virtual board application (VBA) by the hypervisor. The virtual board is the mechanism used by the hypervisor to partition the physical hardware. In a hypervisor system, the guest OS treats the virtual board as a physical target and has no awareness of the physical hardware or other partitions in the system.

virtual board application (VBA)

 

An application that runs natively (directly) on a virtual board without operating system support. This is sometimes referred to as a bare metal application.

One possible Wind River Hypervisor configuration includes the VxWorks guest OS running in a system that includes one or more virtual board applications (each running in its own virtual board context).

virtual board physical address

 

Virtual boards run on physical hardware and the physical hardware has devices at certain physical addresses. When a virtual board's context is created, these physical addresses are translated to a different address as presented to the virtual board. These are virtual addresses to the hypervisor, but they are physical addresses in the virtual board context. These translated addresses are virtual board physical addresses.
