Figure 42: Pixel- and Control Data Flow (Overview)
The flow of data via DMA-access is directed to the main memory to
the address specified by the RISC-program. This address region is
reserved by the user program (e.g. the definition of arrays).
The regions might be defined - as shown in Figure 42
- as two
separate regions, one for the odd- and one for the even field, or only
one region, which is provided for the whole frame of the
pciGrabber-4x4. The different options are selected by a parameter in
the
set_image()
function, which influences the creation of the RISC
program via the driver.
