An attempt has been made to optimize the software energy of real time preemptive tasks by minimizing the cache related preemption costs which are primarily incurred due to the inter-task interference in the cache. We have presented an algorithm that outputs an ”optimum” task layout which reduces the overall inter-task interference in cache and thus reduces the preemption costs of each task of a given task set. We have compared the result of our estimated layout with that of the random layout generated for benchmark examples for demonstrating the performance of our algorithm.
