Abstract: Energy efficiency is one of the biggest challenges of designing future heterogeneous multicore system, beyond performance, hereby, we propose an energy efficiency analytical model for heterogeneous multicore system based on the enhanced Amdahl's law. The model extends the traditional computing-centric model by considering the overhead of data preparation which potentially includes the overhead of communication, data transfer, synchronisation, etc. The analysis clearly shows that decreasing the overhead of data preparation is a promising approach to reach higher performance of computation and greater energy efficiency. Therefore, more informed trade-offs should be taken when we design a modern heterogeneous processor system within limited budget of energy.
