Abstract(in English) | The paper proposes a technique which simultaneously finds the optimal cache way allocation and code placement for given multiple tasks running on a single core processor. It reduces the energy consumption in a set-associative cache by activating only a single cache way at a time and deactivating the remaining cache ways. The technique also reduces the number of cache misses by changing the code placement in a main memory, which results in a reduction of the energy consumption in the main memory as well as the reduction of total execution time. Experiments using a commercial embedded processor demonstrate that the technique reduces the total energy consumption in the target processor system by 17% at the best case compared to the energy of the system which does not apply our technique. |
