The current generation of High Level Synthesis (HLS) tools usually generates hierarchical and modular designs, mimicking the structure of the call graph of the original high-level input specification. The standard approach is to progressively synthesize functions into modules by navigating the application call graph from the leaves up to the top function. In the synthesized architecture, function calls corresponds to the instantiation of the related module into the data path generated for the caller. Our work introduces a methodology that enables sharing of (sub)modules across modules boundaries.

Abstract
The current generation of High Level Synthesis (HLS) tools usually generates hierarchical and modular designs, mimicking the structure of the call graph of the original high-level input specification. The standard approach is to progressively synthesize functions into modules by navigating the application call graph from the leaves up to the top function. In the synthesized architecture, function calls corresponds to the instantiation of the related module into the data path generated for the caller. Our work introduces a methodology that enables sharing of (sub)modules across modules boundaries.File in questo prodotto:
