Abstract
There is provided an apparatus and method for MPEG decoding using dynamically varying voltage and frequency of a processor, wherein an operation frequency and voltage of the processor is set depending on a difference between the number of current frames and that of set frames, in correspondence with the interrupt generated during decoding frames until a next interrupt is generated, to thereby support a real-time decoding. The method herein includes the steps of predicting decoding time until the next interrupt from the current interrupt is generated depending on both a type and size of frames and the system speed.
