METHOD AND A SYSTEM FOR DYNAMIC FREQUENCY ADJUSTMENT DURING VIDEO DECODING, CAPABLE OF ADJUSTING A FREQUENCY OF A PROCESSOR

摘要

PURPOSE: A method and a system for dynamic frequency adjustment during video decoding are provided to reduce unused processing frequencies, thereby reducing power consumption of an AVP(Audio/Video Processor).;CONSTITUTION: A processor measures decode time for performing hardware VLD(Variable Length Decode)(405). Time for which frames are transferred for decoding is recorded(410). Time when VLD about the frames is completed is received(412). The decode time for which the frames is averaged to determine average decode time about the frames(415).;COPYRIGHT KIPO 2010
