物联网（IoT）利用无处不在的互联网连接，将日常物理对象组成一个网络，以实现自动化、远程数据传感和集中管理/控制。IoT对象需要嵌入处理能力来实现这些服务。物联网对象处理单元的设计受到性能、功耗、散热等各种严格要求的制约，为了满足这些不同的要求，需要相应地调整大量的处理器设计参数。在本文中，我们提出了一种时间有效的设计空间探索方法，以确定功率和性能优化的微体系结构配置。我们还讨论了这些微架构配置的可能组合，以形成一个有效的两层异构IoT应用处理器。我们使用一个周期精确模拟器(ESESC)和一组标准的PARSEC和SPLASH2基准来评估我们的设计空间探索方法。结果表明，我们的方法只在3%-5%的设计空间内确定了2.23%-3.69%的微体系结构配置。我们的方法在设计空间探索方面平均达到24.16倍的加速比，而在为处理器寻找功率和性能优化的微架构配置方面则是完全穷尽的探索。

英文摘要：
The Internet of Things (IoT) makes use of ubiquitous internet connectivity to form a network of everyday physical objects for purposes of automation, remote data sensing and centralized management/control. IoT objects need to be embedded with processing capabilities to fulfill these services. The design of processing units for IoT objects is constrained by various stringent requirements, such as performance, power, thermal dissipation etc. In order to meet these diverse requirements, a multitude of processor design parameters need to be tuned accordingly. In this paper, we propose a temporally efficient design space exploration methodology which determines power and performance optimized microarchitecture configurations. We also discuss the possible combinations of these microarchitecture configurations to form an effective two-tiered heterogeneous processor for IoT applications. We evaluate our design space exploration methodology using a cycle-accurate simulator (ESESC) and a standard set of PARSEC and SPLASH2 benchmarks. The results show that our methodology determines microarchitecture configurations which are within 2.23%-3.69% of the configurations obtained from fully exhaustive exploration while only exploring 3%-5% of the design space. Our methodology achieves on average 24.16x speedup in design space exploration as compared to fully exhaustive exploration in finding power and performance optimized microarchitecture configurations for processors.
