Processor power management in handheld devices is the primary technique for exploiting power reduction while ensuring performance. Modern mobile devices require high performance at the system level to decode high-bitrate multimedia. For this reason, processor offloading using off-chip controllers is commonly exercised in this field. However, current power management techniques do not fully consider the offloading architecture. We propose a scheme to achieve power reduction through an empirical method, which detects and classifies off-chip usages, in addition to combining dynamic voltage scaling (DVS) with dynamic power management (DPM). We experimented with the proposed technique in a real hardware environment and achieved up to a 37% power reduction compared with previous schemes.
