Actiniaria: Distributed Dynamic-IR-Drop-Aware Timing Monitor for AVFS With Lightweight Tentacles 150 150
Author(s): Junyi Qian, Lishuo Deng, Cai Li, Yizhi Ding, Weiwei Shan

Abstract:

Advances in integrated circuit (IC) technology have amplified the effects of process, voltage, and temperature (PVT) variations, particularly dynamic IR drop, which severely affects timing. Post-silicon IR drop monitoring circuits are lacking, forcing designers to reserve substantial static guard bands for worst-case scenarios, compromising energy efficiency. Inspired by biomimetics, this …

A Unified Early-Warning AVFS Design With Path Activation-Aware Monitoring Point Optimization

A Unified Early-Warning AVFS Design With Path Activation-Aware Monitoring Point Optimization 150 150
Author(s): Cai Li, Kaize Zhou, Junyi Qian, Haochang Zhi, Weiwei Shan

Abstract:

This work proposes a unified early-warning adaptive voltage-frequency scaling (AVFS) system that offers a practical low-power solution for commercial IoT devices. First, a path activation-aware monitoring point optimization strategy is proposed to mitigate the risk of illegal voltage scaling. The strategy combines the path activation evaluation with the required timing …
