Adaptive multiple switching strategy toward an ideal NoC

The exigency for heterogeneous many-core systems has brought an exponential growth in the complexity of their interconnections. In this manner, other Network-on-Chip (NoC) alternatives are being sought to attend the requirements in terms of power consumption and performance. Nevertheless, several of these proposals present very complex architectures, with virtual channels, tables and extra controls. In this paper we propose the junction of two advantageous strategies: hierarchical topology with adaptability. The use of these two techniques is novel in the literature and it allows ensuring high performance even when the application has their communication rates altered. The gains in power and in performance are possible due to the use of low cost components in a hierarchical structure.
