Integrated modelling and generation of a reconfigurable network-on-chip

While a communication network is a critical component for an efficient system-on-chip multiprocessor, there are few approaches available to help with system-level architectural exploration of such a specialised interconnection network. This paper presents an integrated modelling, simulation and implementation tool. The network architecture can be co-simulated with embedded-software to obtain cycle-accurate performance metrics. This allows an energy and performance tuning of the NOC. Next it can be converted into VHDL for implementation. We discuss our approach by designing a flexible network-on-chip and present implementation results. The performance of our automatically generated network is comparable with a reference design directly developed in HDL.
