该论文介绍了Oracle SPARC M7处理器的细粒度自适应电源管理系统，旨在最大化商业、云和大数据工作负载的性能，同时满足热和电气约束。系统通过毫秒到秒级的时间常数维持硅片温度在目标范围内，并确保电源电流低于阈值。
Curtis McAllister, Ha Pham, Sebastian Turullols, Jinuk Luke Shin, Yifan YangGong, Haowei Zhang Oracle, Redwood Shores, CA The goal of the power management system of Oracle’s SPARC M7 CPU [1] is to maximize the performance of commercial, cloud and big-data workloads subject to thermal and electrical constraints in a variety of system environments. Under thermal constraints, the goal is to maintain silicon die temperature within a target limit with a time constant of milliseconds to seconds, and under electrical constraints the current draw on a supply must be maintained below a threshold with a time constant of microseconds. The processor is designed to run a range of commercial workloads, potentially in virtualized environments, resulting in widely varying activity factors across the chip. Thus, the system must implement a fine granularity of control to achieve maximum performance across the entire
