Abstract :
Power characteristics of different Asynchronous Network on Chip (NoC) architectures are developed. Among different NoC architectures, the Butterfly Fat Tree (BFT) dissipates the minimum power. With increasing the number of IP blocks, the relative power consumption of the interconnects and the associate repeaters of the Asynchronous NoC architecture decreases as compared to the power consumption of the network switches. The power dissipation of the Asynchronous architecture is decreased by up to 57% as compared to the power dissipation of the conventional Synchronous architecture. The BFT is more efficient with increasing the number of IP blocks.
