Abstract :
Increased variability affects the efficiency of dynamic power and thermal management. Existing on-chip sensor infrastructure can be used to improve the inherent thermal imbalances among cores in a multicore architecture. Experimental analysis based on live measurements on a special test chip shows reduced on-chip heating with no performance loss.
