Hi.
In search of vision equipment with good performance/$ ratio I came
across IEEE 1394 (Firewire) cameras. For processing and storage, I
would use a PC with an off-the-shelf Firewire controller board (PCI
based).
In a number of places I read that Firewire consumes quite an amount of
host computer CPU (for example in
http://digital.ni.com/public.nsf/websearch/ED092614FCCC900D86256D8D004A3B0C?OpenDocument
--"
...IEEE 1394 cameras also require processor control
to move the image data, which limits available processor bandwidth for
image processing.")
Does this also apply to the newer IEEE 1394b-2002? As the controller
hardware would allow for DMA, does NI-IMAQ for IEEE 1394 Version 2
(which actiually supports IEEE 1394b) make use of DMA capabilities? If
yes, how much is CPU burden reduced?
If these questions should be silly, please forgive. I am "at home" more
on the optical side of a detector, not at the electronical side.
