24
‑
bit representation of the instantaneous power consumption of
N1 SoC cluster 0:
•
The value of these bits represents [SYS_I_CL0(I) ×
SYS_V_CL0(V)]/617402 watts.
•
Measured power consumption=[SYS_POW_CL0]/617402
watts.
•
The
CB_nRST
reset signal resets the register to zero. The
register then updates every 100µs after the reset.
4.7.12
SYS_POW_PCIE Register
The SYS_POW_PCIE Register characteristics are:
Purpose
Contains a 24
‑
bit representation of the instantaneous power consumption of the PCIe cluster.
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.
