Abstract

In this paper, we propose an intelligent partitioning approach of the system-on-chip (SoC) to improve the bendability and stretchability of flexible and stretchable systems. The proposed approach partitions the SoC intelligently into clusters of functional modules according to the communication flows and area constraint. Based on the communication volume between clusters, a heuristic algorithm is applied to map these clusters onto the 2D mesh network-on-chip (NoC) for co-optimization of communication energy and delay. Experimental results show that our approach can effectively partition the SoC into small ICs of the same size. The approach also reduces power consumption and communication delay by 10.64%–56.63% and 15.06%–50.30%, respectively.
