Data Transfer and Storage
The DT3162 board uses the scatter/gather memory management
architecture so that memory locations do not have to be contiguous.
The board operates as a PCI bus initiator/master using burst mode
for data transfers to memory. Typical video transfer rates are 40 MB/s
(maximum 132 MB/s). Data is stored in monochrome format, or
8-bits per pixel.
Overlays
For the DT3162 board, you can use software to add overlays, such as
text or graphics, on top of another displayed image that was
acquired. Overlays are useful for creating animation or to display
helpful information for the user.
