Abstract (in Japanese) (See Japanese page) 
(in English) As microprocessor grows in density, management of processor temperature is becoming an important issue. Temperature-Aware Dynamic Voltage and Frequency Scaling (TA-DVFS) has been proposed to reduce power and energy consumption by regulating temperature violation. However, using TA-DVFS makes it hard to calculate execution time of task because of change of voltage and frequency by processor temperature.In this paper, we apply Imprecise Calculation model which split each task into mandatory and optional part to TA-DVFS. It regulates processor temperature growth and better utilizes residual slack to get better quality of task while preserving realtime capability by giving up the execution of optional part. Experimental results show that by using the proposed technique, we reduced the number of processor temperature violations and raised the quality of tasks by exploiting residual slack.
