Abstract(in English) | Mobile applications, especially for cellular phones, need to satisfy the requirement for low power consumption keeping multimedia performance high enough. Thus software and hardware combined approach for low power becomes really important. One of such techniques is frequency-voltage cooperative control that lowers the MPU clock and core voltage at the same time when maximum execution speed is not necessary. We applied multi-tasking audio-visual player to frequency-voltage cooperative control with application processor. Frequency-voltage cooperative control makes 50% current reduction under multi-tasking audio-visual player. |
