Integration of embedded, real-time, Ada, operational flight programs with off-line engineering level-of-detail digital models

The integration of an Ada operational flight program (OFP) with a FORTRAN simulation model is described. The architecture of the OFP is described, along with the portions of code necessary to simulate the desired system functions. Differences between the VAX Ada implementation and the Ada compiler for the MIL-STD-1750A microprocessor are discussed, and the necessary workarounds are highlighted. Results of the integration are presented along with approximate level-of-effort estimates for the port.<
