论文摘要

在过去的几十年中,数字电子功能的指数增长主要是由于能够将集成电路(ICS)扩展到较小的维度,同时获得功率和性能益处。由于缺乏缩放晶体管性能以及制造复杂性,现在正在挑战该可伸缩性[1] - [5]。此外,Fables制造时代不断增长的网络威胁构成了现代ICS需要承受的新战线。我们提出了一个新的基于噪声的计算,其中有意设计纳米级金属线之间的互连干扰,以展示可编程的布尔逻辑行为。仅依赖金属线之间的耦合,而不仅仅是用于计算晶体管的耦合,以及可编程性的基础是更好的可伸缩性,也是默默无闻的安全性。在这里,我们显示了在65nm技术下运行的串扰计算芯片功能正常的实验证据。我们对计算构建体的演示,门水平的可配置性和铸造过程的利用率显示出可行性。这些结果与我们在7nm处的模拟结果相结合的各种基准分别显示出超过48%,57%和10%的密度,功率和性能,在最佳情况下在同等的CMO上取得了超过同等的CMO,显示出潜在的潜力。串扰电路和固有的可编程功能的好处使其与众不同,并使它成为未来电子产品的前景。

The past few decades have seen exponential growth in capabilities of digital electronics primarily due to the ability to scale Integrated Circuits (ICs) to smaller dimensions while attaining power and performance benefits. That scalability is now being challenged due to the lack of scaled transistor performance and also manufacturing complexities [1]-[5]. In addition, the growing cyber threat in fabless manufacturing era poses a new front that modern ICs need to withstand. We present a new noise based computing where the interconnect interference between nanoscale metal lines is intentionally engineered to exhibit programmable Boolean logic behavior. The reliance on just coupling between metal lines and not on transistors for computing, and the programmability are the foundations for better scalability, and security by obscurity. Here, we show experimental evidence of a functioning Crosstalk computing chip at 65nm technology. Our demonstration of computing constructs, gate level configurability and utilization of foundry processes show feasibility. These results in conjunction with our simulation results at 7nm for various benchmarks, which show over 48%, 57%, and 10% density, power and performance respectively, gains over equivalent CMOS in the best case, show potentials. The benefits of Crosstalk circuits and inherent programmable features set it apart and make it a promising prospect for future electronics.
