A New Client Interface Architecture for the Modified Fat Tree (MFT) Network-on-Chip (NoC) Topology
A new client interface for the Modified Fat Tree (MFT) Network-on-Chip (NoC) is presented. It is directly inspired from the findings related to lane utilization and maximum FIFO sizes found in simulations of the MFT. A new smart arbitration circuit that efficiently realizes a round-robin scheduler between the receiving lanes has been developed. Simulation results show a clear viability and efficiency of the proposed architecture. The limited number of the active receiving links has been verified by simulations. Simulations also show that the central FIFO size need not be very large.
