【発明の名称】ディスク・キャッシュ制御方式
Document Type and Number:
Japanese Patent JP2854668
Kind Code:
B2
Abstract:
PURPOSE:To obtain maximum disk cache effect by replacing and storing write-in requested data in the same ranking position of a cache memory only when the existence of the above data in the cache memory is retrieved. CONSTITUTION:In the case of data write-in processing, even if a cache hit signal is outputted from a directory control part 14, substitution control to the most significant level of the write-in requested data in the cache memory 12 is not executed. The cache memory 12 can be efficiently used without carrying forward the data of high read-out request rate to a low order storage level, and data processing speed can be speeded up.
