LVME/DFCIO DUAL FUNCTION CUSTOM I/O BOARD

GENERAL OVERVIEW

The LVME/DFCIO Dual Function Custom I/O Board provides emulation for many different I/O resources required in an operational computer.

Those resources are fully programmable, under software control, so the same board may be used when emulating different computers.

The logic is implemented in nine XILINX gate arrays which may be reloaded under software control via the VMEbus.

LVME/DFCIO

The LITAL LVME/DFCIO Dual Function Custom I/O Board is a high performance member of LITAL's line of VMEbus boards. The LVME/DFCIO resides on a standard double height Eurocard form factor (160mm x 239mm). The LVME/DFCIO board takes full advantage of the VMEbus architecture and provides emulation of many different I/O computer resources, occuping only one VMEbus slot.
