Abstract
The present invention discloses a power-aware compiling method, wherein the power model of an application program are established via building and analyzing the control flow chart and the data flow chart of the application program; each functional unit of the application program is assigned a power mode; a judgment is undertaken to determine whether the idle functional units are independent; if none dependency exists between those idle function units, the program codes of the same idle function units are merged into a new basic block, and the idle functional units are turned off for saving power; each new basic block is assigned an appropriate power mode; the basic blocks with the same power modes are merged to reduce the transitions between different power modes; thus, the power consumed by changing voltage or frequency can be decreased.
