2.1.2 PCIS-DDE Device Driver Handling
PCIS-DDE provides a utility, PciUtil. This utility is used for users to make
the registry of PCIS-DDE drivers, remove installed drivers and modify
the allocated buffer sizes of AI, AO, DI and DO. The allocated buffer sizes
of AI, AO, DI, DO represent the sizes of contiguous Initially Allocated
memory for continuous analog input, analog output, digital input, digital
output respectively. Its unit is page KB, i.e. 1024 bytes.
Device driver will try to allocate these sizes of memory at system startup
time. The size of initially allocated memory is the maximum memory size
that DMA or Interrupt transfer can be performed. It will induce an
unexpected result in that DMA or Interrupt transfer performed exceeds the
initially allocated size.
The PciUtil main window is as the following figure. The PciUtil is installed
with PCIS-DDE and located in <InstallDir>\Util directory. You can use it to
register the device drivers you need.
