SYS_POW_SYS Register
The SYS_POW_SYS Register characteristics are:
Purpose
Contains a 24
‑
bit representation of the instantaneous power consumption of the parts of the N1
SoC, outside the clusters, that operate from the VSYS power supply.
Usage constraints
This register is read-only.
Configurations
Available in all N1 board configurations.
Memory offset and full register reset value
See
4.7.1 APB energy meter registers summary
Note
The value measured by this register is provisional and subject to characterization on the RevB boards.
The following table shows the bit assignments.

bit representation of the instantaneous power consumption of
the parts of the N1 SoC, outside the clusters, that operate from the
VSYS power supply:
•
The value of these bits represents [SYS_I_SYS(I) ×
SYS_V_SYS(V)]/1234803 watts.
•
Measured power consumption=(SYS_POW_SYS)/1234803
•
The
CB_nRST
reset signal resets the register to zero. The
register then updates every 100µs after the reset.

SYS_POW_CL0 Register
The SYS_POW_CL0 Register characteristics are:
Purpose
Contains a 24
‑
bit representation of the instantaneous power consumption of N1 SoC cluster 0.
Usage constraints
This register is read
‑
only. You must use one of the cluster 1 cores to read this register.
Configurations
Available in all N1 board configurations.
Memory offset and full register reset value
