<P>PROBLEM TO BE SOLVED: To provide an information processor capable of using a general-purpose storage device for real time control. <P>SOLUTION: The information processor comprises: a state table; a monitoring part; a buffer memory; a timer; a data processing part; and a responding part. The monitoring part monitors the operation state of the storage device and sets the operation state of the storage device as a monitoring result to the state table. When a data-writing is requested from the host device, the responding part instructs the timer to start counting and sets a data-writing destination to the state table; and instructs the data-writing to the storage device for writing. Then, the part causes data for writing, which is sent from the host device for within a certain period of time, to be held in the buffer memory; and when receiving notification that time is up from the timer, it returns a response, which indicates completion of the writing for the write request, to the host device. <P>COPYRIGHT: (C)2013,JPO&INPIT |
