摘　　要：基于已有的TALK算法,提出了基于电热耦合效应的空闲时间均匀分配(TCED)算法.实验表明:TCED算法十分简便,合理地利用空闲时间来降温,解决了TALK算法在较低负载和极高负载情况下的不足.因此TCED算法适用于高性能处理器单元各种工作负载的降温降耗.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.
