Currently, FPGAs serve as Field–Programmable–Systems–on–Chip (FPSoCs) and are widely used to implement computationally intensive applications. As the number of components in FPSoCs increases, the interconnect schemes based on Network–on–Chip (NoC) approach are increasingly used. Routers greatly impact the performance and cost of NoCs. In this thesis, we explore the design space of FPGA–based NoC routers. We implement three types of packet switched NoC routers on a Stratix II FPGA using parameterized VHDL models. To reduce the area and increase the speed, we use novel techniques. Buffer size is decreased by minimizing the number of control fields in a packet. Both edges of the clock are utilized, and credit based flow control is used to accelerate the router. The proposed routers were evaluated based on area, frequency, and zero load latency. Synthesis results and zero load latency evaluations show that they are significantly superior to widely referenced, previously proposed routers.
