CRIS Current Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishCurrent systems-on-chip execute applications that demand extensive parallel processing. Networks-on-chip (NoC) provide a structured way of realizing interconnections on silicon, and obviate the limitations of bus-based solutions. NoCs can have regular or ad hoc topologies, and functional validation is essential to assess their correctness and performance. In this paper, we present a flexible emulation environment implemented on an FPGA that is suitable to explore, evaluate and compare a wide range of NoC solutions with a very limited effort. Our experimental results show a speed-up of four orders of magnitude with respect to cycle-accurate HDL simulation, while retaining cycle accuracy. With our emulation framework, designers can explore and optimize a range of solutions, as well as characterize quickly performance figures.

| Abstract: | Current systems-on-chip execute applications that demand extensive parallel processing. Networks-on-chip (NoC) provide a structured way of realizing interconnections on silicon, and obviate the limitations of bus-based solutions. NoCs can have regular or ad hoc topologies, and functional validation is essential to assess their correctness and performance. In this paper, we present a flexible emulation environment implemented on an FPGA that is suitable to explore, evaluate and compare a wide range of NoC solutions with a very limited effort. Our experimental results show a speed-up of four orders of magnitude with respect to cycle-accurate HDL simulation, while retaining cycle accuracy. With our emulation framework, designers can explore and optimize a range of solutions, as well as characterize quickly performance figures. | |
