Software-generated interrupts (SGIs) are generated by software writing to a GICD_SGIR register in the GIC. The system uses SGIs for inter-processor communication.

An SGI has edge-triggered properties. The software triggering of the interrupt is equivalent to the edge transition of the interrupt request signal.
