Abstract: Based on the existing TALK algorithm,the paper put forward another more effective algorithm-free time evenly distributed technique based on the electric and thermal coupling effect (TCED),which is more convenient and make more rational use of free time to lower temperature and meet the shortfall of TALK when applying to low load and very high load. In sum,TCED algorithm is more universally applied to decrease the temperature and energy consumption for high-performance processor unit with various sizes of workload.
