Abstract

Recently proposed technologies to enhance NoC performance can be applied to only part of the network to save hardware overhead and energy. This paper discussed the influence of network traffic distribution to local optimization efficiency. We introduce two-dimensional finite difference method to quantize the non-uniformity of the NoC traffic. Then, we describe hotspot and potential optimization node (PON) in NoC mathematically and some low-cost architecture support to discover them. Experimental results show that unbalanced traffic pattern may improve the efficiency of some local optimization methods, and PON is a better choice than hotspot to perform single-node optimization.
