Multicore technology is entering the mobile phone domain, and it is termed mobile multicore computing (MMC) in this project. With MMC, the current mobile phones are no longer the traditional mobile phones with only voice and/or video phone functionalities. More features, such as multimedia streaming and mobile P2P applications, are integrated into these small devices. The grand challenge in MMC mobile phones is making a good tradeoff between performance and power. Different from existing hardware-oriented approaches, such as clock gating and power gating for high performance and low power design, this research proposes software-oriented approaches such as power-aware parallelization of mobile applications and power-aware task scheduling to meet this challenge.In this 2-year EAGER project, the PI is seeking answers to this foundational performance/power tradeoff problem. The prposal sets forth four ambitious objectives to do so: 1) To build a performance and power tradeoff model for mobile multicore platforms considering user requirements; 2) To parallelize mobile applications for mobile multicore platforms with memory, timing, and power constraints; 3) To schedule multitasks for multicore platforms with memory, timing, and power constraints; and 4) To develop a prototype mobile system based on mobile multicore computing platforms with high performance and low power consumption. It is expected that the insights and results drawn from this project will benefit researchers, practitioners, users, and students on a large scale.

多核技术正在进入手机领域，在本项目中被称为移动多核计算（MMC）。有了MMC，现在的手机不再是传统的只有语音和/或视频电话功能的手机。这些小型设备中集成了更多功能，例如多媒体流和移动 P2P 应用程序。 MMC 手机面临的巨大挑战是在性能和​​功耗之间取得良好的权衡。与现有的面向硬件的方法（例如用于高性能和低功耗设计的时钟门控和功率门控）不同，本研究提出了面向软件的方法（例如移动应用程序的功耗感知并行化和功耗感知任务调度）来应对这一挑战。在这个为期 2 年的 EAGER 项目中，PI 正在寻找这个基本性能/功耗权衡问题的答案。该提案提出了四个雄心勃勃的目标：1）考虑用户需求，为移动多核平台构建性能和功耗权衡模型； 2) 在内存、时序和功耗限制的情况下，对移动多核平台的移动应用程序进行并行化； 3）为具有内存、时序和功耗限制的多核平台调度多任务； 4）开发基于高性能、低功耗移动多核计算平台的原型移动系统。预计该项目的见解和结果将使研究人员、从业者、用户和学生大规模受益。
