The Aon, Claxon and Cyton families CoaXPress Frame Grabbers
CXP-1-2 BitFlow, Inc. Version C.1
ware platform supports. The concept of the virtual frame grabber is described below,
but basically the idea is that one hardware platform can support more than one
device. In the case of the Aon, Claxon and Cyton , these devices are frame grabbers.
Note that we are not using the word virtual here in the sense of “a software virtualiza-
tion of a hardware device”, these VFGs are real hardware. The reason we using “vir-
tual” is because the term “frame grabber” has more than one meaning. It can mean
the piece of hardware that you put in your computer, or it can mean the device that
the your software application is controlling and getting images from. For the pur-
poses of this manual, “virtual frame grabber” means the device that your application
is interfaces with. While this might sound complicated, the implementation is simple.
You plug our Cyton-CXP frame grabber into your PC, and your application interacts
with one or more VFGs available. Everything else is taken care of by the BitFlow driv-
ers.
1.1.4 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.
1.1.5 Configuration Spaces
The Aon, Claxon and Cyton models supports different numbers of 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. The following figures show the block diagrams
for each possible configuration.
