Nature-Inspired Interconnects for Self-Assembled Large-Scale Network-on-Chip Designs

Christof Teuscher

摘要:

未来的纳米级电子产品由Avogadro数量的组件组成,需要高效,高度可扩展和强大的通信手段,以便与传统的硅方法竞争。近年来,片上网络(NoC)作为一种有前途的解决方案出现在硅基电子互连的挑战。目前的NoC架构要么是高度规则的,要么是完全定制的,这两者都代表了新兴的自下而上的自组装分子电子学的难以置信的假设,这些电子学通常被认为具有高度的不规则性和不完美性。在这里,我们务实和实验研究重要的设计权衡和属性的不规则的,抽象的,但物理上合理的3D小世界互连结构的灵感来自现代网络芯片范例。我们改变框架的关键参数,如连接,交换节点的数量,分布的长距离与短距离连接,并测量网络的相关通信特性。我们进一步探讨了对链路故障的鲁棒性和解决一个简单的玩具问题,同步任务的能力和效率。结果证实:(1)不规则组件中的计算是自组装纳米尺度电子学的一种有前途和破坏性的计算范例;(2)具有幂律衰减分布的短路径长度的3D小世界互连结构在物理上是合理的,并且比局部2D和3D规则拓扑结构具有重大优势。

英文摘要:

Future nano-scale electronics built up from an Avogadro number of components needs efficient, highly scalable, and robust means of communication in order to be competitive with traditional silicon approaches. In recent years, the Networks-on-Chip (NoC) paradigm emerged as a promising solution to interconnect challenges in silicon-based electronics. Current NoC architectures are either highly regular or fully customized, both of which represent implausible assumptions for emerging bottom-up self-assembled molecular electronics that are generally assumed to have a high degree of irregularity and imperfection. Here, we pragmatically and experimentally investigate important design trade-offs and properties of an irregular, abstract, yet physically plausible 3D small-world interconnect fabric that is inspired by modern network-on-chip paradigms. We vary the framework's key parameters, such as the connectivity, the number of switch nodes, the distribution of long- versus short-range connections, and measure the network's relevant communication characteristics. We further explore the robustness against link failures and the ability and efficiency to solve a simple toy problem, the synchronization task. The results confirm that (1) computation in irregular assemblies is a promising and disruptive computing paradigm for self-assembled nano-scale electronics and (2) that 3D small-world interconnect fabrics with a power-law decaying distribution of shortcut lengths are physically plausible and have major advantages over local 2D and 3D regular topologies.
