Information processor and information processing method

Abstract

According to one embodiment, an information processor includes a connector, a determination module, a recognition module, and a cache control module. The connector connects a storage device to the information processor. The storage device is used as a cache by an operating system which controls the information processor. The determination module determines whether to use the storage device connected to the information processor as a data readable and writable storage area. The recognition module causes the operating system to recognize the storage device as a storage area when the determination module determines to use the storage device as a storage area. The cache controller controls the operating system to use the storage device as a cache when the determination module determines not to use the storage device as a storage area.

Dependencies are inferred from the claim text.
