4.7.1
APB energy meter registers summary
The base memory address of the APB energy meter registers in the IOFPGA is
0x1C01_0000
.
The APB energy meter registers contain values that represent supply currents, supply voltages, and
power consumption in the N1 SoC.
The IOFPGA energy registers relate to the following parts of the N1 SoC:
• N1 clusters, 1 and 0.
• CCIX and PCIe PHY cluster.
• The fabric of the N1 SoC outside the clusters, that is, the parts of the chip that operate from the
VSYS power supply.
The IOFPGA energy registers measure the following values of each block:
• Instantaneous current consumption.
• Instantaneous voltage supplies.
• Instantaneous power consumption.
• Cumulative energy consumption.
• N1 clusters, 1 and 0.
• CCIX and PCIe PHY cluster.
• The fabric of the N1 SoC outside the clusters, that is, the parts of the chip that operate from the
VSYS power supply.
