A Process-Scheduler-Based Approach to Minimum Energy Point TrackingA Process-Scheduler-Based Approach to Minimum Energy Point Trackingengポスター発表http://id.nii.ac.jp/1001/00198621/Conference Paperhttps://ipsj.ixsq.nii.ac.jp/ej/?action=repository_action_common_download&item_id=198711&item_no=1&attribute_id=1&file_no=1Copyright (c) 2019 by the Information Processing Society of JapanDepartment of Communications and Computer Engineering, Graduate School of Informatics, Kyoto UniversityDepartment of Communications and Computer Engineering, Graduate School of Informatics, Kyoto UniversityInformation System Platform Unit, Graduate School of Informatics, Nagoya UniversityDepartment of Communications and Computer Engineering, Graduate School of Informatics, Kyoto UniversityShengyu, LiuJun, ShiomiTohru, IshiharaHidetoshi, OnoderaIn this paper, we define the minimum energy point (MEP) as a set of supply voltage (VDD) and threshold voltage (VTH) which can Minimize the energy consumption of CMOS processor under a determined performance constraint. Due to the characteristic of MEP, the coordinate of MEP varies violently when condition of processor changes (e.g. temperature, performance constraint and activity factor ). In order to keep the processor working at MEP under various working condition, in this paper, we proposed an process-scheduler-based MEP Tracking for soft real-time system. This process-scheduler-based MEP tracking system is designed to determine the appropriate performance constraint and find the corresponding operating voltage by using both sensing information form processor and working condition from the process scheduler. We built a prototype of the process-sechduler-based MEP tracking system by using a 32-bit RISC processor fabricated with 65-nm process technology which shows that this tracking system can track the MEP while the ambient operating condition and workload widely change.In this paper, we define the minimum energy point (MEP) as a set of supply voltage (VDD) and threshold voltage (VTH) which can Minimize the energy consumption of CMOS processor under a determined performance constraint.
