Ragionando sul fallimento finito e le computazioni infinite usando l’interpretazione astratta
The paper concerns the concept of refinement as a commonly used design practice in the software development process. The refinement relationship is formulated and formally expressed for UML collaborations. Collaborations are suitable for presenting the proposed approach as they represent both static and dynamic aspects of a modeled system or its part, for example, a use case. Our approach to refinement is based on the rule of preserving the observable behavior of a modeled system. The introduced...
The recourse to operation research solutions has strongly increased the performances of scheduling task in the High-Level Synthesis (called hardware compilation). Scheduling a whole program is not possible as too many constraints and objectives interact. We decompose high-level scheduling in three steps. Step 1: Coarse-grain scheduling tries to exploit parallelism and locality of the whole program (in particular in loops, possibly imperfectly nested) with a rough view of the target architecture....
