Management Communications and Control, Inc. (MCCI) proposes a hardware/software architecture to develop and resuse airborne applications on a multiple vendor family of COTS processors. The architecture's design environment provides an open application program interface (API) to member hardware platforms. Software tools will automatically generate high performance applications code for family hardware targets from common, reusable, graphical application specifications. Board replacement ILS strategies will be supportable without expensive software maintenance or indefinite commitment to a particular vendor's hardware. Reusable software fault isolation testing may be incorporated directly into applications. The architecture family's open API offers the Navy the opportunity to reuse the AN/UYS-2 application code at minimal cost.
