Packet-switched on-chip FPGA overlay networks


Kapre, Nachiket Ganesh (2006) Packet-switched on-chip FPGA overlay networks. Master's thesis, California Institute of Technology.


As we scale to larger chip capacities, it becomes possible to map large, concurrent applications to programmable fabrics. These applications often have irregular and dynamic communication requirements. Packet-switched networks provide efficient implementations for such applications on these fabrics. In this research, we show how to engineer high-performance packet-switched on-chip networks and provide quantitative comparisons between different kinds of these networks. We analyse different network topologies and justify selection of topologies based on experimental results. We investigate packet-switched and time-multiplexed styles of routing and provide guidance on which style is appropriate for which application.
