1.1.3 The Virtual Frame Grabber (VFG)
The idea behind the VFG is to separate the hardware platform (connectors, laminate,
FPGAs, etc.) from the frame grabbing functionality that software applications work
with. The primary reason behind this separation is that the turn around time for hard-
ware is much longer than the turn around time for modifying virtual frame grabbers.
To create a brand new virtual frame grabber, or to modify an existing one, simply
requires writing new firmware or updating existing firmware.
The idea of modifying a frame grabber by making changes to its firmware is not new.
BitFlow has been doing this since its very first product. However, unique to BitFlow
products is the fact the entire frame grabber is written in firmware. The only fixed
hardware components are the interfaces to the outside world (e.g. the interface chips
on the front end). Everything else that makes up the board, camera control, data buff-
ering, DMA engine, etc. is written in firmware. This gives the platform incredible levels
of flexibility and opens the door to unlimited customization.
1.1.4 Cyton Configuration Spaces
The Cyton-CXP model supports four VFGs. Each VFG appears to operating system
and your software as a separate device. Each VFG will can connect to one or more
CXP links. Figure 1-1 shows the block diagram of the for board.7
