Learning is its own reward. Nothing I can say is better than that.

The main aim of this thesis is to propose enhancing techniques for the per-formance in Networks on Chips. In addition, a concrete proposal for a pro-tocol stack within our NoC platform Nostrum is presented. Nostrum inherently supports both Best Effort as well as Guaranteed Throughput traf-fic delivery. It employs a deflective routing scheme for best effort traffic delivery that gives a small footprint of the switches in combination with robustness to disturbances in the network. For the traffic delivery with hard guarantees a TDMA based scheme is used. During the transmission process in a NoC several stages are involved. In the papers included, I propose a set of strategies to enhance the perform-ance in several of these stages. The strategies are summarised as follows Temporally Disjoint Networks is that a physical network, potentially, can be seen to contain a set of separate networks that a packet can enter dependent on when it enters the physical network. This has the consequence that w
