Machine Learning Based Negative-Bias Temperature Instability (Nbti) Detection and Mitigation for Heterogeneous Multi-Core Systems(2/2)

Project Details

Description

As CMOS technology continuous scaling down, a single chip can perform complicated data processing. Heterogeneous Multi-core System(HMS) can provide higher performance by appropriately performing task-to-core assignment. On the other hand, aging effect has become one of the most drastic challenges in modern IC design. Negative-Bias Temperature Instability (NBTI) effect can result in increased threshold voltage of pMOS transistors and may lead to timing failure after circuit aging. To mitigate or tolerance NBTI, previous researches developed different design structures as well as optimization strategies. However, only a few studies focus on NBTI-induced problems on HMSs. Therefore, in the proposal, we want to deeply study these NBTI-induced problems on HMSs, and develop a machine learning based algorithm to detect the aging situation of different modules in the HMSs, and propose a system level NBTI mitigation strategy.Specifically, this proposal addresses on the following two problems:1.Using machine learning algorithm to deploy and calibrate aging sensors in different modules of HMSs.2.NBTI-aware HMS system lifetime extension strategyWe will use machine learning algorithm to appropriately deploy aging sensors, and then develop a task-to-core mapping algorithm to extend the HMS system lifetime.
