A method to reconstruct thermal signals on chip withnon-uniformly spaced samples

The runtime on-chip thermal signal is essential information for dynamic thermal management(DTM).This paper proposes a method based on Voronoi diagram to reconstruct thermal signals with non-uniformly spaced samples,by applying this method on a 16-core processor with 9 thermal sensors on each core,it can reconstruct the thermal signal of the processor with average error as small as 2.25%,and proves the superiority of our proposed method to inverse distance weight by comparing the average runtime of each other.
