Aa leading supplier of oil well logging services,
had several hundred well logging systems in service throughout the
world. Faced with requirements to provide more extensive analysis by
supporting additional tools, instruments, and sensors, Gearhart chose to
extend the capabilities of this first generation system by linking the
existing minicomputer to a high performance VME computer.
Since the necessary interface was not commercially available,
Gearhart selected Mitsi to develop an interface to link the two transfer
busses.
SOLUTION
Mitsi developed a Bus Adapter Subsystem that provides all the
necessary handshaking routines, synchronization, and protocol
translation necessary to effect high speed (2 Mbytes/sec ) data transfer
between the host and VME coprocessor. The coprocessor can relieve the
host of a variety of time consuming and memory intensive tasks with the
added benefit of extended I/O capabilities through the VME bus.
RESULTS
Incorporation of VME technology via the Bus Adapter Subsystem has
significantly extended the DDL-1's operating life and has enhanced its
capability to provide more exhaustive measurement of well parameters.
