Boeing Phantom Works has successfully completed two flight tests of a new Advanced Display Core Processor (ADCP) for the F-15E. This processor is an important part of a much larger Boeing project called Boldstroke, which is tasked with prototyping military computer systems for tactical aircraft using lower-cost, easier-to-use, commercially available technology. The DMV-177 PowerPC Single Board Computer (SBC), manufactured by DY 4 Systems Inc., is an integral part of the new ADCP from General Dynamics Information Systems.
A prototype ADCP was built to demonstrate the potential replacement of both the central computer and multipurpose display processor on the F-15E aircraft. In this particular demonstration, the DMV-177 SBC was linked to a commercially available 5 x 5 in. color liquid crystal display and controlled by object-oriented software. According to DY 4 Systems Inc., these components performed together as expected.
The DMV-177 is a 64-bit microprocessor designed for harsh, rugged, realtime applications such as those experienced on the F-15E. It has 64 MB of DRAM, 10 MB of Flash EPROM, 256 kB of EPROM, and a high level of I/O fuctionality. Its PowerPC processor runs at 200 MHz. Different versions of the DMV-177 have been used in the Army's M1A2 Abrams battle tank and, most recently, in the upgrade of teh AV-8B Harrier under the Open Systems Core Requirement (OSCAR) program for the U.S. Marine Corps.
