摘要:
A central processing unit (CPU) carries out selected reset interruption processing by using a vector address preset in accordance with an interruption source to generate an address to a data table whose contents are used to initialize selected registers. In this manner, the CPU can be reset without having first stored the processing state of the CPU in response to a reset interrupt request, without the need for extensive dedicated reset hardware, and with the ability to select desired reset values that can differ as between different interrupts and can be changed from time to time.

A central processing unit has a plurality of control sections; a device for selectively operating and unoperating the control sections by an external interrruption signal; and a device for processing an interruption sequence with respect to the interruption signal by the operations of the control sections in a state in which the control sections are operated. The control processing unit may be constructed such that the control sections are composed of two control sections and one of the two control sections processes a normal instruction sequence and is unoperated by the interruption signal, and the other of the two control sections is operated at the times of the normal instruction and interruption and processes the interruption sequence in addition to the normal instruction.

A method of producing a chromium-containing steel sheet hot-dip plated with aluminum. A steel sheet containing not less than about 3 wt % of chromium is pre-plated at each side thereof with an iron-phosphor alloy so that a pre-plating layer of the iron-phosphor alloy about 0.05 to 3.0 .mu.m thick is formed on each side of the steel sheet. The steel sheet is heated and then subjected to an aluminum hot-dip plating by being dipped in a bath of molten aluminum or a molten aluminum alloy. An undercoat nickel plating layer may be formed on the steel sheet in advance of pre-plating with the iron-phosphor alloy.

Information processing methods to make it possible to reserve recording of a program without imposing a large burden on a user. A server transmits program attribute information to a video recording and reproducing apparatus via a network. The program attribute information includes program attribute names and program attribute retrieval conditions. The video recording and reproducing apparatus causes a display apparatus to display a list of the program attribute names. The user selects from the list a program attribute name to which a program that the user wishes to reserve for recording seems to be most closely related. The video recording and reproducing apparatus compares the retrieval conditions corresponding to the selected program attribute name and EPG (electronic program guide) information and, when the retrieval conditions are satisfied, records a program represented by the EPG in a recording reservation list. The methods can be applied to a hard disk video recorder.
