BRIGE: Energy-Efficient and High-Bandwidth Reconfigurable Mobile Memory Interface for Heterogeneous Mobile Computing

智能优点：当前的移动接口信令技术，如仅基带和多电平信令，具有严重的技术限制，特别是不可重新配置的数据访问、有限的带宽和超线性能量消耗。Brige项目的目标是通过在多核处理器和存储器子系统之间使用新颖的同时双向和可重配置的多数据访问互连来分析、设计、制造和验证适用于异构移动计算的高能效和高带宽可重配置的移动存储接口。这种互连可以显著降低由图像(或生物)传感器接口单元和通用多核、图形(或图像)和数字信号处理器等不同处理单元组成的异类多核系统的多个并发任务负载。在该项目完成后，我们预计我们将开发出一种创新的移动界面，该界面将允许未来的移动界面在智能手机(或平板电脑)和超便携计算系统等移动设备中提供能效和带宽方面的显著进步。此外，拟议的关键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，从而为未来移动芯片之间的移动接口提供新的见解和潜在的解决方案，这些移动芯片之间的接口需要更高的能效和更高的带宽。广泛的影响：提出的异质多核处理器和存储系统之间的移动可重构接口有望通过利用不断改进的硅工艺来同时提高移动设备的能效和带宽，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微电子和集成电路设计的知识和见解的学生，帮助培养一支具有全球竞争力的工程学劳动力队伍，改善学术界和工业界之间的合作研究，帮助扩大妇女和少数群体在工程学领域的参与，并通过广泛的外联活动改善本科工程学教育。具体地说，将被应用设计经验(LEAD)项目招收的女性和代表不足的本科生，将成为他们顶峰设计经验的一部分，作为其顶峰设计经验的一部分，该项目多年来一直成功地将女性和代表不足的群体招募到皮？S系的毕业项目中。

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.
