摘要

描述了一种32nm SOI关键路径监视器(CPM),它可以为8核POWER7+™微处理器中的数字锁相环提供定时测量,用于动态频率调整。CPM校准到2%的周期时间内,从标称到涡轮电压。其电压灵敏度为10mV/bit。它跟踪处理器温度灵敏度在标称频率的1.5%以内,采样抖动小于标称频率的1.5%。动态检测噪声的能力允许系统在任何给定电压下运行处理器,使其更接近其最佳频率,从而降低电压以节省电力或提高频率以提高性能。

Single-cycle, pulse-shaped critical path monitor in the POWER7+ microprocessor
A 32nm SOI critical path monitor (CPM) that can provide timing measurements to a Digital PLL for dynamic frequency adjustments in the 8-core POWER7+™ microprocessor is described. The CPM calibrates to within 2% of cycle time from nominal to turbo voltages. Its voltage sensitivity is 10mV/bit. It tracks processor temperature sensitivity to within 1.5% of nominal frequency, and has a sample jitter less than 1.5% of nominal frequency. The ability to detect noise dynamically allows the system to operate the processor closer to its optimal frequency for any given voltage, resulting in lower voltage for power savings or higher frequency for performance improvements.
