Augmenting NoC with Naming Service for Slot-based Reconfigurable Devices on Chip

In recent years, special attention has been paid to slot-based reconfigurable devices interconnected by NoCs (networks on chip). An urgent problem is how one reallocatable task can communicate with others. This paper proposes two approaches to augment NoC for slot-based reconfigurable system by adding a naming module to solve this problem. In the first approach, the naming module is outside of the mesh and connects to each slot using a dedicated channel. In the second approach, the naming module is inside the mesh and communicates with other slots using NoC routing. As for the results, for the best situation in a 16×16 mesh, average delay increases by 1.15% and by 6.00% for over-network mode and in-network mode respectively. These two average delays would increase with increasing reconfiguration rate, with the increase for the in-network mode being faster than that for the over-network mode. And the decrease of throughput is negligible in both modes.
