About the Interrupt Controller
The Interrupt Controller is a single functional unit that is located in a Cortex®â€‘A9 MPCore design. It is responsible for centralizing all interrupt sources before dispatching them to each individual Cortexâ€‘A9 processor. There is one interrupt interface per Cortexâ€‘A9 processor.
The Interrupt Controller is memory-mapped. The Cortexâ€‘A9 processors access it by using a private interface through the SCU.
