SYS_POW_GPU 24-bit representation of the instantaneous power consumption of the Mali-T624 GPU cluster:
•
The value of these bits represents [SYS_I_GPU(I) × SYS_V_GPU(V)]/617402 watts.
•
Measured power consumption=[SYS_POW_GPU]/617402 watts.
•
The
CB_nRST
reset signal resets the register to zero. The register then updates every 100µs after the
reset.
