JPS583044A - Interruption system - Google Patents

Abstract

PURPOSE:To simplify an interruption system, by reducing complicated procedures such as switching or arrangement of switches, etc., and the quantity of hardwares for constituting a register and the switch. CONSTITUTION:An interruption signal from a magnetic disk device 2 is set to an interruption register 5a and 5b through a signal bus 20a and 20b, respectively, and is informed to a magnetic disk controller 3a and 3b through signal buses 21a, 21b, respectively. The magnetic disk controller 3a applies a reset signal to the interruption register 5a through a signal bus 22a, and executes a prescribed processing for the interruption. When the processing ends, it is informed to a switch control part 4 through a signal bus 7a, and a switch 11a is turned off. Also, it is informed to the switch control part 4 through a signal bus 7b, a switch 11b is turned on, the interruption register 5b is reset through a signal bus 22b, and a prescribed interruption processing is executed.

Description

[Detailed description of the invention] The non-invention relates to the interrupt method L41 asynchronous interrupt 91lt
The present invention relates to a magnetic disk drive control adapter that is effective when applied to a magnetic disk drive.

The following explanation uses a magnetic disk controller as an example. Notification of the OS inclusion signal to the disk system #system is performed by a return signal from the magnetic disk m* device of the series that received the m inclusion notification, and the friend Osb is a magnetic disk control device,
-Rino-Integrated system #Kll included registers Sa, Sb and PCI registers 6a and 6b for setting interrupts of other systems are prepared.
゜11a,llb,H! a, l! 7a and b are signal paths for 1 hour from 020 to m4 where bell enemy LII will meet.

Interrupt compensation 4#-is issued from the magnetic disk disk offset 2, and the interrupt register lea is set in the signal path Ojima by the switch IOK, and then the magnetic disk control device 8aK is notified from the signal path 21m. The magnetic disk controller 8 & sets the interrupt register 51 and the III system PCI register 6 via the signal path 228 and the switch 11 &, and issues a predetermined interrupt after notifying the disk controller 3bK. Perform electric layer. After that, Jlqi Dista l
111IIllI&position 3& is notified to the switch # section 4 via the signal path 7a.

In order to turn off the switches l1m and 12a and set the switch 101 to neutral, the disk control device 8b detects that the switch 10 is neutral and is number 9, and then notifies the switch control 54 and turns on the switch file and the switch 12b pipe yK. , switch 1
O1-interrupt register sb fold I! O Hand-made interrupt set/re-ky) method Tehiro, switch 100@enemy, Pcl register of other systems O Hirahara's Sosuke such as setting by return signal, and hardware 1-A that constitutes the switch in the register There was a drawback that the amount was large.

The present Ii beak O1#Hiro, the above-mentioned drawbacks, small amount of blades and simplification of the interrupt method.

Non-controlled devices and multiple! A control adapter that connects the 1194 device is provided with a switch control S, and a switch control S is installed on the I to support multiple scissors control devices.
sets the interrupt signal from the non-scissor control device to the plurality of interrupt registers and notifies the control device, and the control device then sends the interrupt signal to the interrupt register. The second fiA is characterized in that it is reset by turning on and off the scissors M* switch by the selection control of the sill switch control section, and the details will be clarified in the explanation using llAt. In one embodiment, the magnetic disk control adapter Om is included in the circuit diagram. In the figure, l is the magnetic disk control adapter.

2 is a magnetic disk device as a non-control device, 3a and sb are magnetic disk control devices of different systems, 5 and sb are interrupt registers, and 4 is a switch control unit. 21B, 7&, b are signal paths, and 11& is an in-line switch.
