MOVING PICTURE ENCODING OR DECODING PROCESSING SYSTEM AND MOVING PICUTURE ENCODING OR DECODING PROCESSING METHOD

摘要

There are suggested a moving picture encoding or decoding processing system and a moving picture encoding or decoding processing method capable of reducing the power consumption as compared to the conventional technique. A necessary calculation amount Kp required for encoding or decoding one frame is calculated and an operation frequency F capable of encoding or decoding the necessary calculation amount Kp within the time T assigned for the encoding or decoding of the frame is decided. The one frame is encoded or decoded by operating the processor with the operation frequency F and the operation voltage V appropriate for the operation frequency F. Furthermore, at least one failure evading means is provided for evading the failure phenomenon which occurs when the necessary calculation amount Kp is smaller than the actually necessary calculation amount.
