ABSTRACT:
A computer-implemented method for handling pending interrupt vectors of a pending interrupt list is disclosed. The method includes batch-reading the set of pending interrupt vectors into a working list of working interrupt vectors. The method also includes performing interrupt handling of the working interrupt vectors using an interrupt handling arrangement until the working list is empty. The interrupt handling process permits a first incoming interrupt vector that is received by the pending interrupt list after the batch reading to temporarily interrupt the performing interrupt handling of the working interrupt vectors and to be handled on a priority basis by the interrupt handling arrangement if a priority level of the first incoming interrupt vector is higher than a priority level of a first working interrupt vector being currently handled by the interrupt handling arrangement.
