A method called pipeline stage unification (PSU) has been proposed to reduce power consumption for modern processors, which can work as an alternative for Dynamic Voltage Scaling (DVS) technology. In this paper, we proposed two mechanisms for PSU controller which can dynamically predicate a suitable unification based on the program phase detection. Our results show that the two mechanisms can achieve an average Energy Delay Product (EDP) decreasing of 15.1% and 19.2% for SPECint2000 benchmarks, compared to the processor without PSU.
