Energy efficient scheduling of real-time tasks on multi-core processors with voltage islands
A Voltage Island Largest Capacity First (VILCF) algorithm is proposed. VILCF fully utilizes the capacity of voltage islands to achieve energy efficiency. The energy consumption is optimal when the workloads of all cores are balanced. The approximation ratio is bounded by a value depending on the number of islands.
