Objective:The objective of this project is to lay the groundwork for completely re-thinking Network-on-Chips (NoCs) design and propose to exploit the unique advantages of the emerging interconnect technologies such as photonics and wireless for designing performance scalable, and power-efficient NoCs for future multicores.Intellectual Merits:Power consumed by digital devices and systems such as smartphones, laptops, servers and datacenters is increasing at an alarming rate as more computing cores can be integrated on a single chip. The computing capabilities of multicore architectures can be unleashed only if the underlying network that transports data between the cores and the caches can provide scalable bandwidth at low power consumption. Research has shown that disruptive technology solutions such as photonics and wireless technologies have the potential to alleviate the critical bandwidth, power, and latency challenges of future multicore architectures. The proposed research combines multiple interconnect technologies to achieve three objectives, namely: (1) scalability to 1000 cores, (2) power efficiency (at least a 50% reduction as compared to state-of-the art metallic interconnects), and (3) high bandwidth and low latency across a wide variety of applications.Broader Impacts:The proposed research has the potential to transform the design of next-generation NoCs and multicore architectures, which are essential for the continued growth of computing performance. This proposal describes a transformative and viable approach that integrates research in technology, architecture, algorithm and applications for designing energy-efficient NoCs thus enabling scalable multicore architectures. The research will also play a major role in education by integrating discovery with teaching and training. Finally, the results and findings of the proposed research will be disseminated to researchers, engineers and educators through technical publications and presentations.

目的：该项目的目的是为完全重新思考网络上的网络（NOC）设计奠定基础，并提议利用新兴互连技术的独特优势，例如光子学和无线化的性能，以设计性能可扩展的noc和功能效率的NOC，例如未来的多功能级数：Intellectual liless.intellectual interpect。以惊人的速度增加，因为可以将更多的计算核心集成到单个芯片上。只有在核心和缓存之间传输数据的基础网络可以在低功耗以低功耗提供可扩展的带宽时，才能释放多核体系结构的计算能力。研究表明，诸如光子学和无线技术之类的破坏性技术解决方案有可能减轻未来多层体系结构的关键带宽，功率和延迟挑战。拟议的研究结合了多种互连技术，以实现三个目标，即：（1）对1000个核心的可伸缩性，（2）功率效率（与艺术金属互连相比，至少降低了50％的降低50％），（3）跨越的应用程序的范围和低延迟。体系结构，这对于持续增长计算性能至关重要。该提案描述了一种变革性且可行的方法，该方法将技术，体系结构，算法和设计用于设计节能NOC的应用程序整合，从而启用可扩展的多核心体系结构。这项研究还将通过将发现与教学和培训相结合，在教育中发挥重要作用。最后，拟议研究的结果和发现将通过技术出版物和演示文稿传播给研究人员，工程师和教育者。
