Formal Semantics of Array-OL, a Domain Specific Language for Intensive Multidimensional Signal Processing
Résumé
In several application domains (detection systems, telecommunications, video processing, etc.) the applications deal with multidimensional data. These applications are usually embedded and subjected to real-time and resource constraints. The challenge is thus to provide efficient implementations on parallel and distributed architectures. Array-OL has been designed specifically to handle this kind of intensive multidimensional signal processing applications. In this paper we present the language and its formal semantics. A subset of Array-OL, Static Array-OL, is defined that ensures the existence of a static scheduling. Finally, we discuss how to map and schedule an Array-OL application on a parallel and distributed architecture.
