Abstract
Ex2 is an extended Ada executive which is portable across hardware targets, is reusable across Ada compilers, provides the EXTRA HRT-oriented extensions to Ada defined by the RRG and is designed to service the needs of avionics systems. Ex2 interface to the compiler is consequently public and has been adequately designed. Ex2 architecture is highly modular and heavily influenced by its portability and safety objectives. This architecture allows for a fine-grain customizability of Ex2 to client systems constraints. This architecture integrates deeply the support of EXTRA/RRG services and prepares Ex2 to support Ada9X new real time features.
Ex2 study has been funded through the Technical Service for Aeronautical Telecommunications and Equipments (DGA/DCAÉ/STTE), contract 93/86024 00 470 7588.
