Abstract

【課題】　低消費電力化を図りながらも、破綻現象を回避することができる動画像符号化又は復号化処理システム及び動画像符号化又は復号化処理方法を提案する。 【解決手段】　所定フレームの符号化又は復号化に必要な必要演算量を計算する必要演算量計算手段２と、所定フレームの符号化処理又は復号化処理に予め割り当てられている時間Ｔｅ内に前記必要演算量を符号化処理又は復号化処理可能な動作電源電圧及び基板バイアス電圧及び動作周波数を計算する動作決定手段３とを備え、時間Ｔｅ内は前記プロセッサ１が前記算出された一定の動作周波数及び動作電源電圧及び基板バイアス電圧で動作しながら所定フレームの符号化又は復号化処理を行い、さらに、必要演算量計算手段で算出された必要演算量が実際に必要な演算量よりも小さい場合におこる破綻現象を回避する破綻回避手段を備える。
