Realization of an Ada architecture for heterogenous distributed embedded processors

Heterogeneous processing systems have long been used for the design of avionics architectures. Until recently, this architecture took the form of federated or “black box” systems. Advanced architectures characterized by terms such as integrated open systems, and modular avionics, are now being adopted by the DoD. Consistent with new hardware designs, are burgeoning software technologies. These include megaprogramming, and programming in the large, and object-oriented development, and a host of design methodologies. This paper attempts to reconcile these often divergent technologies given the real-time rigors of Digital Signal Processing (DSP) applications and the mandate to use the Ada programming language. Beginning with an overview of the state of DSP and software methodologies, Ada program building blocks are then presented with the unique intent of defining reusable software components for any platform of heterogeneous distributed embedded processors
