摘要： A controller for controlling interrupt processing in a multiple-interrupt system is provided. The controller includes multiple watchdog timers (WDTs), each provided for each of interrupt priorities. The controller includes interrupt priority selectors, each of which receives each interrupt request signal and outputs an activation signal to a corresponding WDT according to the priority of the interrupt request signal. The controller includes an interrupt processing circuit, which when a WDT has timed out, outputs, to a processor, an interrupt request signal having a priority one or more levels higher than the priority corresponding to the WDT. When multiple causes of interrupt are assigned to one of the interrupt priorities, the interrupt processing circuit gives priority to an interrupt request signal caused by the timeout of a WDT lower in priority level than the interrupt priority to detect that an abnormal operation has occurred in interrupt processing having the lower level priority.

摘要： Provided is a method for recording data to a tape medium in such a manner as to achieve the easy management of mutually related multiple data pieces. First data and second data continuously received as a file from a higher level apparatus are accumulated in multiple buffer segments in the form of multiple successive data sets. A data structure is determined for each of the accumulated data sets. Management information indicating a result of the determination is added to the data sets, and the data sets and the management information thereof are stored into the tape medium.

摘要： A tape recording apparatus is configured for sequentially recording files when receiving a command to write the files from an external host. The tape recording apparatus includes a buffer for temporarily storing the files, a tape on which the files are recorded, a writing device for writing the files stored in the buffer on the tape, and a writing control device for performing control of sequentially writing the files stored in the buffer on the tape one by one. The writing control device memorizes designated delimiter positions when delimiter position designation commands are received from the external host, the delimiter position designation commands designating the delimiter positions of the files to be sequentially written.
