As interest in architectural designs for “Internet of Things (IoT) edge computing” is growing, conflicting requirements between energy-efficiency and design-productivity are becoming remarkably crucial. Owing to the increasing diversity of IoT applications, the domain-oriented designs of processors should be reassessed. By focusing on one application domain that is control-intensive and mainly operates “light” computations, we examine issues of current processor designs, present simple and energy-efficient processors, and justify the design strategies that we employed. Our evaluation shows the effectiveness of our processors, in terms of circuit area and energy-efficiency, over ARM Cortex-M0, and reveals important findings in architectural designs for severely constrained IoT edge computing.

重新审视面向边缘计算的简单且节能的嵌入式处理器设计

随着对“物联网 (IoT) 边缘计算”架构设计的兴趣不断增长，能效和设计生产力之间的冲突要求变得非常重要。由于物联网应用的多样性日益增加，应该重新评估面向领域的处理器设计。通过关注一个控制密集型且主要操作“轻”计算的应用领域，我们检查了当前处理器设计的问题，展示了简单且节能的处理器，并证明了我们采用的设计策略的合理性。我们的评估显示了我们的处理器在电路面积和能效方面优于 ARM Cortex-M0 的有效性，并揭示了严重受限物联网边缘计算架构设计的重要发现。
