Performing high-level synthesis via program transformations within a theorem prover

In this paper, we present a new methodology towards performing high-level synthesis. During high-level synthesis an algorithmic description is mapped to a structure of hardware components. In our approach, high-level synthesis is performed via program transformations. All transformations are performed within a higher order logic theorem prover thus guaranteeing correctness. Our approach is not restricted to data flow graphs but supports arbitrary computable functions, i.e. mixed control/data flow graphs. Furthermore, the treatment of algorithmic and interface descriptions is orthogonalised, allowing systematic reuse of designs
