Generic Interrupt Controller

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.
Implementation Details
The configuration and control for the GIC is memory-mapped and accessed through the SCU. The GIC
are clocked by

Note: To ensure that you are using the correct GIC interrupt number, your code should refer to the
symbolic interrupt name, as shown in the Interrupt Name column. Symbolic interrupt names are
defined in a header file distributed with the source installation for your operating system
