Peripheral interrupts are asserted by a signal to the GIC. The GIC architecture defines the following types of peripheral interrupts.

Private peripheral interrupt (PPI) is a peripheral interrupt that is specific to a single processor.

Shared peripheral interrupt (SPI) is a peripheral interrupt that the distributor can route to any of a specified combination of processors. These are wired interrupts coming from various sources to the GIC.

Each peripheral interrupt is either edge-triggered or level-sensitive.
