Engineers at the Marconi Electronic Systems Avionics Group in Edinburgh, Scotland, needed single-board computers for video map generators on the Royal Air Force`s Harrier jump jet, as mission symbol generators on the Jaguar aircraft, and as computer symbol generators on the Tornado fighter-bomber.
They chose the CCA-105 single-board computers — a custom-format repackaging of the DMV-177 PowerPC single-board computers — from DY 4 in Kanata, Ontario. The boards will replace Motorola 68020-based processor cards in all three aircraft.
"DY 4 understands our technical and programmatic goals, so they have been very responsive," says Stuart Forsyth, business director, Avionics Group at Marconi Electronic Systems. "It was an added bonus that they delivered the advanced development models a week early."
The CCA-105 features a 100 MHz PowerPC 603e processor, with four megabytes of Flash EPROM, 16 megabytes DRAM, 128 kilobytes of brown-out protected SRAM, 128 kilobytes of EEPROM, and two RS232 serial channels.
Environmental modifications of the DMV-177 boards that DY 4 engineers made included reducing the board in area by 15 percent and core-cooling the boards with a copper layering to meet 90 degrees Celsius card edge operating temperature requirements. — J.M.
