Abstract
Embodiments include a system and method for an interrupt controller that propagates interrupts to a subsystem in a system-on-a-chip (SOC). Interrupts are provided to an interrupt controller that controls access of interrupts to a particular subsystem in the SOC that includes multiple subsystems. Each subsystem in the SOC generates multiple interrupts to other subsystems in the SOC. The interrupt controller processes multiple interrupts and generates an interrupt output. The interrupt output is then transmitted to a particular subsystem.
