Swallow Project : Power Measurement

Oscilloscope-based measurements for calibration

V_B = 1000mV [3rd B item] = 0x666
I_B = 515mV [4th B item] = 0x34C

V_IO = 3.294V
I_IO (Vdrop = 0.0078V). = ADC reading of 0x100

1V cores:
AEC: 18mV across shunt = ADC reading of 0x24E
Active: 26--28mV across shunt = ADC reading of 0x375

With four cores burning, four cores AEC, 1192mW
With all cores burning, 1900mW

Core stripe power consumption:

500MHz (100ref): ~700mW
200MHz (100ref): ~480mW
50MHz (10ref): ~ 140mW
