Summary:To optimize a waveform of a general-purpose bus during the operation of an apparatus.SOLUTION: The general-purpose bus controller, controlling a general-purpose bus connected with a device, includes: a drive circuit for driving a general-purpose bus; a memory table for previously storing an optimum waveform at the general-purpose bus; and a waveform check circuit for checking a waveform of the general-purpose bus. Acquisition means acquires a checked waveform. Comparison means compares the acquired waveform to the previously stored optimum waveform. Change/setting means can execute setting to change an optimum value of a drive circuit according to a comparison result.SELECTED DRAWING: Figure 6 【課題】装置の運用中において汎用バスの波形を最適化すること。【解決手段】デバイスに接続された汎用バスを制御する汎用バス制御装置は、汎用バスを駆動するドライブ回路と、汎用バスでの最適波形を予め記憶するメモリテーブルと、汎用バスの波形をチェックする波形チェック回路と、を備える。取得手段は、チェックした波形を取得する。比較手段は、取得した波形と予め記憶した最適波形とを比較する。変更・設定手段は、比較結果に応じて、ドライブ回路の最適値を変更するように設定可能である。【選択図】図６
