ABSTRACT:
An interrupt controller for a disk controller includes an interrupt scanner module that receives a plurality of interrupt requests (IRQs) from a plurality of corresponding interrupt sources, performs a scan of respective vector values of the plurality of IRQs, and selectively outputs a priority based on the scan. An interrupt generation module receives the priority and generates at least one of a fast interrupt and a regular interrupt based on the priority.
