Abstract :
This work analyzes the mapping of applications onto generic regular networks-on-chip (NoCs). Cores must be placed considering communication requirements, so as to minimize the overall application execution time and energy consumption. We expand previous mapping strategies by taking into consideration the dynamic behavior of the target application and thus potential contentions in the intercommunication of the cores. Experimental results for a suite of 22 benchmarks and various NoC sizes show that a 42% average reduction in the execution time of the mapped application can be obtained, together with a 21% average reduction in the total energy consumption for state-of-the-art technologies.
