These registers can be read from the BOARD_PARAMS offset in the FPGA.
DSP_A 3.3V is a value that equates to the corresponding voltage using this equation;
V = ( DSPn3.3V / 4096 ) * 3.3
DSP_A core is a value that equates to the corresponding voltage using this equation;
V = ( DSPn core / 4096 ) * 2.5
The DDR, FPGA, and DSP core PSU voltages are also referenced to a fraction of 2.5V.
i.e.
V = ( value / 4096 ) * 2.5
The DSP_A 3.3V supply is passed through a 0.150 Ohm resistor.
The DSP_A core supply is passed through a 0.056 Ohm resistor.
Knowing the voltage drop across these resistors, the current (and hence the power) can be
calculated.
