NAME
xvi50 - Imaging Computer card
DESCRIPTION
The Imaging Computer card (VI50) is used in conjunction with the EdgeII-v
graphics board to display image and graphics data on a single workstation
monitor. It resides with the EdgeII-v on the VME backplane of Intergraph
6187-series workstations. The card is accessed with the Enhanced VME
adapter card resident on the SRX bus.
Currently, each workstation supports only one VI50 device. This device is
referred to as channel 0.
To PIO data to or from the VI50, use the vi50_map() function to map the
board's registers and memory into user space and use pointers to access
the mapped region. A currently-opened channel from the vi50_open()
function must be specified in the call.
To DMA data to or from the VI50, use the vi50_dma() function, specifying
the direction of transfer and a currently-opened channel from the
vi50_open().
