4.3
N1 SoC interrupt maps
The N1 SoC contains three independent interrupt maps for the
Application Processors
(APs), the
System
Control Processor
(SCP), and the
Manageability Control Processor
(MCP).
This section contains the following subsections:
•
4.3.1 Application Processor interrupt map
•
4.3.2 System Control Processor interrupt map
•
4.3.3 Manageability Control Processor interrupt map
4.3.1
Application Processor interrupt map
The GIC-600 implements two types of interrupt. Private Peripheral Interrupts (PPIs) exist separately for
each core. Shared Peripheral Interrupts (SPIs) are shared between all cores.
The following table shows the Private Peripheral Interrupts (PPI) for the application processors. The map
repeats for each core in the subsystem.
