Co-Design of Many-Accelerator Heterogeneous Systems Exploiting Virtual Platforms
Modern multiprocessor heterogeneous systems incorporating multiple hardware accelerators on chip have resulted in an excessive increase in the complexity of hardware/software co-design. Designers have now to explore a design space including both per-accelerator architectural parameters as well as inter-accelerator combinations, i.e. different design configurations among the allocated accelerators, as each accelerator instance has different computational requirements, according to different input data, while throughput and area constraints should be met as well. Under such a system scenario, virtual platform prototyping suffers from increased design time phases, since it requires an exponentially larger number of evaluations to succeed adequate coverage of the design space.
