ABSTRACT:
A method and apparatus is provided for assuring balanced servicing of interrupts among devices at the same interrupt level in a daisy-chain architected bus, such as the VME bus, by detecting that a second device on the same level as a first device is having an interrupt serviced, and responsive thereto raising the interrupt level of the first device.
