As the demand for feature-rich mobile systems such as smart phones and wearables has outpaced other computing systems and is expected to continue at a faster rate, it is projected that mobile systems with tens of cores and hundreds of accelerators (IPs) will be designed to provide unprecedented level of features and functionality in future. Design of such systems with the required QoS and power budgets along with other design constraints will be a daunting task for computer architects, since any ad hoc, piece-meal solution is unlikely to result in an optimal design. This requires early exploration of the complete design space to understand the system-level design trade-offs. Unlike a rich set of simulation tools available for conducting architecture research, there is no publicly available simulation infrastructure for design and evaluation of existing and emerging handheld platforms that covers the complete hardware and software stack.The goal of this CRI Community Infrastructure (CI) project is to develop an open-source simulation tool, called GEMDROID, for facilitating architectural research on mobile platforms. The project encompasses the following tasks:(i) Integrate the open-source Android emulator, GEM5 architecture simulator and a wide variety of IPs and sensors to faithfully simulate a wide variety of mobile applications on a target SoC platform; (ii) Incorporate power modelling tools in GEMDROID for power/energy analyses; (iii) Extend GEMDROID to simulate wearables/IoTs; (iv) Validate the performance and power models with detailed measurements; and (v) Develop a benchmark suite for handheld platforms.The proposed GEMDROID simulator is expected to be the first open-source tool for researchers and practitioners to conduct a wide variety of design and evaluation work on mobile systems. The platform would be disseminated to the broad research community, with regular workshops and tutorial organized for building a community of users and developers for this toolset. The infrastructure would serve as a teaching aid in our undergraduate and graduate courses on mobile architectures. The outreach activities include participation in the U-Science program at Penn State to engage K-12 students, educators, undergraduate and graduate students, and interested community members in the STEM fields and the VIEW (Visit-In-Engineering Weekend) program to expose them to this important area.

由于对诸如智能电话和可穿戴设备的功能丰富的移动的系统的需求已经超过了其他计算系统，并且预计将以更快的速度继续，预计具有数十个核心和数百个加速器（IP）的移动的系统将被设计为在未来提供前所未有的特征和功能水平。设计这样的系统所需的QoS和功率预算沿着与其他设计约束将是一个艰巨的任务，计算机架构师，因为任何特设，零碎的解决方案是不可能导致最佳的设计。这就需要对整个设计空间进行早期探索，以了解系统级设计的权衡。不同于一套丰富的模拟工具可用于进行架构研究，有没有公开可用的模拟基础设施的设计和评估现有的和新兴的手持平台，涵盖了完整的硬件和软件stack.The CRI社区基础设施（CI）项目的目标是开发一个开源的模拟工具，称为GEMDROID，促进建筑研究的移动的平台。该项目包括以下任务：（i）集成开源Android模拟器、GEM 5架构模拟器以及各种IP和传感器，以在目标SoC平台上忠实地模拟各种各样的移动的应用;（ii）在GEMDROID中纳入功率建模工具，以进行功率/能量分析;（iii）扩展GEMDROID以模拟可穿戴设备/物联网;（iv）通过详细的测量来验证性能和功率模型;（iv）在GEMDROID中添加新的功率模型。及（v）为手提平台开发一套基准测试套件。拟议的GEMDROID模拟器可望成为首个开放源码工具，供研究人员和从业员就移动的系统进行各种设计和评估工作。该平台将向广大研究界传播，并定期举办讲习班和辅导班，以建立这套工具的用户和开发人员社区。该基础设施将作为我们的本科生和研究生课程的移动的架构的教学辅助。外展活动包括参与宾夕法尼亚州立大学的U-Science计划，以吸引K-12学生，教育工作者，本科生和研究生以及STEM领域的感兴趣的社区成员，以及VIEW（访问工程周末）计划，使他们了解这一重要领域。
