Table 4-38 SYS_ENM_A53 Register bit assignments
Bits
Name
Function
[63:32] SYS_ENM_H_A53 Most significant 32 bits of a 64-bit representation of the accumulated energy consumption of the
Cortex-A53 cluster:
•
The memory address offset of these bits is
0x0114
.
•
Accumulated energy = (SYS_ENM_H_A53:SYS_ENM_L_A53)/12348030000 joules.
•
The
CB_nRST
reset signal resets the register to zero. The register then updates every 100µs after
the reset.
[31:0]
SYS_ENM_L_A53 Least significant 32 bits of a 64-bit representation of the accumulated energy consumption of the
Cortex-A53 cluster:
•
The memory address offset of these bits is
0x0110
.
•
Accumulated energy = (SYS_ENM_H_A53:SYS_ENM_L_A53)/12348030000 joules.
•
The
CB_nRST
reset signal resets the register to zero. The register then updates every 100µs after
the reset.
