The thermal maps of this package are the thermal images used in this paper

K. Dev, A. N. Nowroz and S. Reda, "Power Mapping and Modeling of Multi-core Processors," in IEEE International Symposium on Low-Power Electronics and Design, pp. 39-44, 2013.

They were captured by running various workloads on a 45 nm AMD Athlon II X4 610e quad-core processor running at 1.7 GHz. The floorplan is given in AMDfloorplan.jpg

The thermal maps are given in Celsius and they can be plotted in matlab using imagesc. For instance, the included 
thermal_map.png was generated from this Matlab script

load('tmaps.mat')
for i=1:30
    subplot(6, 5, i)
    imagesc(tmaps(:,:, i))
    colormap(jet)
    colorbar;
    set(gca, 'CLim', [26, 62]);
end

The order of the maps from 1 to 30 corresponds to the following applications and cores

MapNum	core-1	core-2	core-3	core-4
1	omnetpp			
2		omnetpp		
3			omnetpp	
4				omnetpp
5	hmmer			
6	soplex			
7	gamess			
8	omnetpp		omnetpp	
9	hmmer		hmmer	
10	soplex		soplex
