Digital data apparatus for transferring data between NTDS and bus topology data buses

摘要

A program driver means is disclosed that allows for the exchange of information between a NTDS device and a device having a bus topology, especially a VMEbus. The program driver utilizes chain commands which are fully programmable at the user level. The processor itself is programmed at the register level to assure the fastest data rate possible (32 bit access) across the VMEbus. The processor driver is invisible to the user.
