Abstract
An interrupt controller may receive a plurality of interrupts from a variety of sources. An interrupt source register may be utilized to determine the interrupt source. A prioritizer may then determine the priority of each interrupt based on the source of the interrupt. The prioritizer then controls which interrupts are forwarded to a vector generator. The vector generator calculates a interrupt service routine vector of the highest priority interrupt for the core processor. As a result, the core processor receives only the highest priority interrupt vector. When the core processor has finished processing the highest priority interrupt, in some embodiments, the next highest priority interrupt vector is then forwarded for handling.
