Power aware method and apparatus of video decoder on a multi-core platform
Disclosed is a power aware method and apparatus of video decoder on a multi-core platform. The power aware apparatus comprises a power management unit, and a processor unit having an entropy decoder and a decoder. The processor unit has at least one voltage and at least one frequency. One processor of the multi-core platform performs the entropy decoding for a frame, collects the entropy decoded information, and computes the decompressing time. Based on the computed decompressing time, the processor sets up the voltage and frequency for other or all processors to reduce power consumption for video decoders.
