Abstract
A genetic algorithm based mapping and
routing approach called GAMR is proposed for low energy
design of 2D mesh based Network on chip (NoC) under
communication bandwidth constraint. The aim is to min-
imize total communication energy consumption and max-
imum link bandwidth of the NoC architecture. GAMR
automatically maps IP cores of given application onto
NoC architecture and generates a deterministic deadlock-
free minimal routing path for each communication trace.
The evaluation performed on various multimedia bench-
mark applications con¯rms the e±ciency of the proposed
approach. Experimental results show that GAMR saves
about 20% of energy consumption and 30% of link band-
width requirement on average compared to the existing
algorithms.
