Multi-core processing platforms have an increasingly broad range of applications. From consumer multimedia to image processing to defense applications, new designs containing large numbers of embedded cores are emerging. Network-on-Chip (NoC) has emerged as an enabling technology to integrate large numbers of embedded cores in a single die. In spite of all its advantages, a serious performance limitation in a traditional NoC arises from its planar metal interconnect-based multi-hop communication, wherein the data transfer between two distant blocks gives rise to high latency and energy dissipation. These problems can be simultaneously resolved if all or some of the wired links in a NoC are replaced by high-bandwidth single-hop wireless channels. Moreover, wireless links will alleviate the problem of wire congestion in NoCs.Recent research has uncovered excellent emission and absorption characteristics leading to antenna-like behavior in carbon nanotubes (CNTs). This opens up new opportunities for detailed investigations regarding the possibility of building a wireless NoC (WiNoC) with CNT antennas and subsequently making the WiNoC robust against performance uncertainties inherent in nanodevices. The CAREER proposal?s overall research objective will be attained by pursuing two specific goals: 1) Establish design trade-offs and evaluate performance of WiNoC architectures; the proposed WiNoC has the capability to outperform corresponding wireline architectures; 2) Apply error control codes to make the WiNoC robust against possible malfunctions; by incorporating efficient channel coding schemes, the WiNoC will be made robust against varied types of malfunctions. The research proposed here is significant, as it addresses the on-chip interconnect problem from a fundamentally new perspective, namely by developing a wireless network at the nanoscale, as opposed to pursuing incremental improvements of relatively traditional methods of wire-line interconnection. By bringing the world of radio communication to the on-chip environment, the proposed research has the capability to transform the design of multi-core chips. The educational objective of the proposal is to recruit and retain undergraduates, high school students and students from the underrepresented groups in the engineering program. Exposure to research will be accompanied by proactive enabling activities, including broad spectrum introduction to engineering and individualized assistance to increase academic preparedness of the targeted students. The educational activities are expected to enhance research and educational opportunities for underrepresented students in the PI?s department. Advancement of such students is expected to have broad societal impact.This award is funded under the American Recovery and Reinvestment Act of 2009(Public Law 111-5).

多核处理平台有着越来越广泛的应用。从消费类多媒体到图像处理再到国防应用，包含大量嵌入式内核的新设计不断涌现。片上网络（NoC）已经成为一种使能技术，将大量的嵌入式内核集成在单个芯片中。尽管其所有的优点，在传统的NoC中的严重的性能限制来自其平面金属互连的多跳通信，其中两个遥远的块之间的数据传输引起高延迟和能量耗散。这些问题可以同时解决，如果所有或部分的有线链路在片上网络被替换为高带宽的单跳无线信道。此外，无线连接将缓解NoCs中的有线拥塞问题。最近的研究发现，碳纳米管（CNTs）具有优异的发射和吸收特性，导致天线般的行为。这为详细研究使用CNT天线构建无线NoC（WiNoC）的可能性开辟了新的机会，并随后使WiNoC对纳米器件固有的性能不确定性具有鲁棒性。职业建议？的总体研究目标将通过追求两个具体目标来实现：1）建立设计权衡和评估WiNoC架构的性能;所提出的WiNoC具有优于相应有线架构的能力; 2）应用错误控制码使WiNoC对可能的故障具有鲁棒性;通过结合有效的信道编码方案，WiNoC将对各种类型的故障具有鲁棒性。这里提出的研究是显着的，因为它解决了芯片上的互连问题，从一个全新的角度来看，即通过开发一个无线网络在纳米级，而不是追求相对传统的方法的有线互连的增量改进。通过将无线电通信的世界带到片上环境中，所提出的研究有能力改变多核芯片的设计。该提案的教育目标是招收和留住本科生、高中生和工程专业代表性不足群体的学生。接触研究将伴随着积极的使能活动，包括广泛的介绍工程和个性化的援助，以提高目标学生的学术准备。教育活动，预计将提高研究和教育机会不足的学生在PI？的部门。这类学生的进步预计将产生广泛的社会影响。该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助。
