Redistributor miscellaneous input signals
The Redistributor receives signals that identify the status of each core. It also has a tie-off signal that provides the Redistributor with a unique identifier.
Table 2-8 Redistributor miscellaneous input signals
|cpu_active||Input||This signal indicates if the core is active and not in a low-power
state such as retention. The GIC can decide to target only active cores for 1 of N
SPIs. See Performance Monitoring Unit.
Notecpu_active is not synchronized into the Redistributor. If cpu_active is driven from a different domain, it must be synchronized externally.
|ppi_id[15:0]||Input||This tie-off signal provides the Redistributor with a unique identifier that is used primarily to ensure that the GIC is correctly integrated into the system.|
