Abstract
PURPOSE: To increase a processing speed and reduce the capacity of a control storage by reading successively micro instructions from the control storage while using contents of a selected program address register as read addresses and executing these micro instructions.
CONSTITUTION: Program address registers 2 store read addresses of control storage 3 where a micro program is stored and are equipped correspondingly to respective channels, and one of registers 2 is selected according to contents of channel address register 1 which stores temporarily an interrupt channel number. Contents of selected register 2 are used as read addresses to read successively micro instructions from control storage 3 and execute these micro instructions, and simultaneously, contents of selected register 2 are updated to execute the interrupt processing of the interrupt chanel. As a result, the processing speed can be increased, and the capacity of control storage 3 can be reduced.
