comprehensive lower bound estimation from behavioral descriptions
In this paper, we present a comprehensive technique for lower bound estimation (LBE) of resources from behavioral descriptions. Previous work has focused on LBE techniques that use very simple cost models which primarily focus on the functional unit resources. Our cost model accounts for storage resources in addition to functional resources. Our timing model uses a finer granularity that permits the modeling of functional unit, register and interconnect delays. We tested our LBE technique for both functional unit and storage requirements on several high-level synthesis benchmarks and observed near-optimal results.
