Abstract

　データ退避処理又はデータ復帰の際に消費される電力を低減可能なデータ退避システム及びデータ復帰システムを提供すること。 　データ転送システムは、退避データを有する機能ブロックと、機能ブロックから転送された退避データを記憶する記憶部と、機能ブロックと記憶部とが接続された、特定ビット数のビット幅を有するバスと、データ退避処理時に退避期間クロックを機能ブロック及び記憶部に送り、データ復帰時に復帰期間クロックを機能ブロック及び記憶部に送る制御部とを備える。退避期間クロックに同期して、機能ブロックは、バスのビット幅数内の所定ビット数ずつ退避データをバスに送出し、記憶部は、バスを介して機能ブロックから順次送られた退避データを記憶する。復帰期間クロックに同期して、記憶部は、格納された退避データをバスのビット幅数ずつバスに送出し、機能ブロックは、バスから所定ビット数ずつ退避データを読み取る。
