ABSTRACT:
An interrupt program selection system which is provided with a central processing unit executing various types of control programs stored in a storage unit and which accepts an interrupt processing request from an external unit and selects from the storage unit an interrupt program corresponding to the accepted request comprises an interrupt request controller, a conversion table, and a jump code generating module. The interrupt request controller selects a highest-priority processing request from a plurality of interrupt processing requests. The conversion table contains start addresses of a plurality of interrupt programs corresponding to a plurality of interrupt processing requests. The jump code generating module generates a jump code which may be executed directly by the central processing unit as an instruction based on the start address of the interrupt program corresponding to the accepted interrupt processing request, and places the generated code in a memory space in the storage unit.
