10.3.12.1. Functional Description

The PL390 Generic Interrupt Controller (GIC) supports up to 180 interrupt sources, including dedicated peripherals and IP implemented in the FPGA fabric. In a dual‑core system, the GIC is shared by both Cortex®-A9 processors. Each processor also has 16 banked software‑generated interrupts and 16 banked private peripheral interrupts, which occupy GIC interrupt numbers 0 to 31.
