F-16A/B improved REO display set modular architecture

The modular avionics architecture used in the F-16A/B Improved Radar Electro-Optical (REO) Display makes use of existing standards, both industry and military. The architecture uses the IEEE-1296 backplane bus to interconnect the modules performing multiprocessing, MIL-STD-1553, RS-232, and High Speed Data Bus communications with external digital subsystems, and EIA-RS-170A and RS-343 for interfacing with video sources and displays. This architecture permits insertion of additional modules providing new functionality and technology. Many of the shortcomings of Ada for an architecture of this type, such as indeterminacy and lack of scheduling methods other than the Pragma Priority, are avoided by using a run-time kernel and statically allocating the load modules.<
