Abstract

The technical problem refers to the global signaling of locally generated interrupts. Until now, the prob- lem was solved by polling with global barriers of interrupts. The new idea allows a universal interrupt handling. It is also possible to save code for one-chip module- drivers. Beside of the present possibility of switching the global interrupt control on or off, the new solution reports appearing interrupts during a global barrier phase.
