A.9 Performance monitoring signals
List of performance monitoring signals. There are as many PMUEVENT buses as there are Cortex®‑A9 processors in the design.
Table A-23 Performance monitoring signals
|PMUEVENTn[57:0]||O||Performance Monitoring Unit (PMU) or External Performance Monitoring Unit||
Performance Monitoring Unit event bus for CPUn.
The Cortex®‑A9 Technical Reference Manual describes the signals and events.
|PMUIRQ[N:0]||O||System Integrity Controller or External Performance Monitoring unit||Interrupt requests by system metrics, one per Cortex‑A9 processor.|
|PMUSECURE[N:0]||O||External Performance Monitoring unit||
