Huffman tables dynamically while the traditional encoders have no such behavior. We omit giving
further details on the M-JPEG encoder as they are not crucial for the experiments performed here.
Interested readers may refer to (Pimentel et al, 2002). Figure 10 shows the bandwidth requirements and
energy consumptions for M-JPEG encoder application. From the figure it is clear that our approach out
perform other approaches. Figure 11 shows the behavior of NSGA-II with respect to number of
generations.
Figure 12 shows a important performance comparison “many-many” mapping versus “oneone”
mapping between core and switch. The figure shows that “many-many” mapping saves up to (70-
72) % of energy consumption and up to 20% of maximum link bandwidth in compare to “one-one”
mapping. Further the figure shows that the saving factor increases with increase of the dimension of
NoC architecture for more complex applications.
