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).

多核处理平台的应用范围越来越广泛。从消费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) 已成为一种将大量嵌入式内核集成到单个芯片中的支持技术。尽管具有所有优点，但传统片上网络中基于平面金属互连的多跳通信存在严重的性能限制，其中两个遥远块之间的数据传输会导致高延迟和能量耗散。如果将NoC中的全部或部分有线链路替换为高带宽单跳无线通道，则可以同时解决这些问题。此外，无线链路将缓解片上网络中的线路拥塞问题。最近的研究发现，碳纳米管 (CNT) 具有出色的发射和吸收特性，可实现类似天线的行为。这为详细研究使用 CNT 天线构建无线 NoC (WiNoC) 的可能性以及随后使 WiNoC 能够抵抗纳米设备固有的性能不确定性提供了新的机会。该职业提案的总体研究目标将通过追求两个具体目标来实现： 1) 建立设计权衡并评估 WiNoC 架构的性能；所提出的 WiNoC 能够胜过相应的有线架构； 2) 应用错误控制代码，使 WiNoC 对可能出现的故障具有鲁棒性；通过结合高效的信道编码方案，WiNoC 将能够抵御各种类型的故障。这里提出的研究意义重大，因为它从一个全新的角度解决了片上互连问题，即通过开发纳米级的无线网络，而不是追求相对传统的有线互连方法的渐进改进。通过将无线电通信领域引入片上环境，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募和留住工程项目中的本科生、高中生和弱势群体的学生。接触研究将伴随着积极主动的支持活动，包括广泛的工程学介绍和个性化帮助，以提高目标学生的学术准备。这些教育活动预计将增加 PI 部门中代表性不足的学生的研究和教育机会。此类学生的进步预计将产生广泛的社会影响。该奖项由 2009 年美国复苏和再投资法案（公法 111-5）资助。
