PI: Gyungsu ByunInsitution: West Virginia UniversityIntellectual Merit: Current mobile interface signaling technologies such as baseband-only and multi-level signaling have critical technological limitations, particularly non-reconfigurable data access, limited bandwidth and super-linear energy consumption. The objective of this BRIGE project is to analyze, design, fabricate and verify an energy-efficient and high bandwidth reconfigurable mobile memory interface for heterogeneous mobile computing by using novel simultaneous bidirectional and reconfigurable multiple data access-capable interconnect between multi-core processors and memory subsystem. This proposed interconnect can significantly reduce the multiple concurrent task loads of heterogeneous multi-core systems that consist of different processing units such as image (or bio) sensor interface units and general-purpose multi-core, graphics (or image) and digital signal processors. At the completion of this project, it is our expectation that we will have developed an innovative mobile interface that will allow future mobile interfaces to provide significant advances of energy efficiency and bandwidth in mobile devices such as smart phones (or tablets) and ultraportable computing systems. Furthermore, the proposed prototype chip fabrication and testing of critical MBI circuits and systems will play key roles in providing novel computer architecture-level innovations, resulting in new insights and potential solutions for future mobile interfaces between mobile chips which need both much better energy efficiency and much higher bandwidth.Broader Impacts: The proposed mobile reconfigurable interface between heterogeneous multi-core processor and memory system can be expected to improve simultaneously both energy efficiency and bandwidth of mobile devices by using continuous improvement of silicon technologies and to provide new opportunities to industrial and consumer electronics for nonvolatile (or volatile) memory and system on chip applications. The project will also help develop a globally competitive engineering workforce by training students capable of integrating knowledge and insights from the proposed microelectronic and integrated circuit designs, improve collaborative research between academia and industry, help broaden participation of women and minorities in engineering fields, and improve undergraduate engineering education through extensive outreach activities. Specifically, women and underrepresented undergraduate students who will be recruited by the Lane Experienced in Applied Design (LEAD) program, which has been successful in recruiting women and under-represented groups into the graduation program in the PI?s department for many years, will become actively involved in the proposed research project as part of their capstone design experience.

智力优势：当前的移动接口信令技术，如基带和多级信令，具有关键的技术局限性，特别是不可重构的数据访问，有限的带宽和超线性的能量消耗。该bridge项目的目标是通过在多核处理器和存储子系统之间使用新型的同时双向可重构多数据访问互连，分析、设计、制造和验证用于异构移动计算的节能、高带宽可重构移动存储接口。这种互连可以显著减少异构多核系统的多个并发任务负载，这些系统由不同的处理单元组成，如图像（或生物）传感器接口单元和通用多核、图形（或图像）和数字信号处理器。在这个项目完成后，我们期望我们将开发出一种创新的移动接口，这将使未来的移动接口在智能手机（或平板电脑）和超便携式计算系统等移动设备中提供能源效率和带宽的重大进步。此外，所提出的关键MBI电路和系统的原型芯片制造和测试将在提供新颖的计算机体系结构级创新方面发挥关键作用，从而为需要更高能效和更高带宽的移动芯片之间的未来移动接口提供新的见解和潜在的解决方案。更广泛的影响：在异构多核处理器和存储系统之间提出的移动可重构接口可以通过使用不断改进的硅技术，同时提高移动设备的能源效率和带宽，并为工业和消费电子产品的非易失性（或易失性）存储器和片上系统应用提供新的机会。该项目还将通过培训能够整合拟议的微电子和集成电路设计的知识和见解的学生，促进学术界和工业界之间的合作研究，帮助扩大妇女和少数民族在工程领域的参与，并通过广泛的外展活动改善本科工程教育，从而培养具有全球竞争力的工程劳动力。具体来说，女性和未被充分代表的本科生将被Lane应用设计经验（LEAD）项目招募，该项目成功地招募了女性和未被充分代表的群体进入PI的毕业项目。将积极参与拟议的研究项目，作为他们顶点设计经验的一部分。
