Microprocessor board aids simulator displays

Engineers at Kollsman Inc. of Merrimack, N.H., needed an interface controller to run high resolution on a CRT for their Night Targeting System Upgrade for helicopter simulators. So they chose the MR-CPU540 multiprotocol multiprocessor board from Matrix Corp. of Raleigh, N.C.

Engineers at Kollsman Inc. of Merrimack, N.H., needed an interface controller to run high resolution on a CRT for their Night Targeting System Upgrade for helicopter simulators. So they chose the MR-CPU540 multiprotocol multiprocessor board from Matrix Corp. of Raleigh, N.C.

"We needed to run high resolution on a small color monitor," says Dayle Rhodes director of international marketing Kollsman. "But, the only resolution available is 640 by 480. We solved that problem by using a black-and-white CRT with a three-color shutter system, but the bad news was that the drive format is three times the rate of a normal scan converter. The CPU540 became the scan converter for the resolution screen."

Kollsman designers will use the first systems in their Manned Flight Simulator at Patuxent River Naval Air Station, Md., for the U.S. Marine Corps AH-1W Super Cobra 2F170 Aircrew Procedures Trainer.

Driving the simulator is the MR-CPU540 I/O processor board from Matrix consisting of three concurrently operable processing units: one MC68040 and two MC68360 multiprotocol I/O processors, all operating at 25 MHz.

Each processor is independent, which enables the CPU540 to realize real-time performance and relieve I/O bottlenecks and receive support for redundancy. - J.M.
