Nvidia patents fast voltage switching for stable datacenter chips
Nvidia describes a circuit that quickly adjusts a chip's operating speed when voltage changes occur. It uses a fast path to send immediate instructions to the oscillator, then switches to a slower, more precise control loop once the speed stabilizes.
In the filing’s own words
Voltage-Frequency domain switching circuits that include multiple stages each configured to receive a throttle code, each of the stages providing a fast-propagation path for the throttle code to a digitally controlled oscillator, and a frequency locked loop configured to (a) generate a code to the digitally controlled oscillator over a slow path, and (2) disable the fast path to the digitally controlled oscillator upon the code satisfying a match with the throttle code.
What exactly they claim (claim 1)
1. A circuit comprising: a fast-propagation path configured to propagate a first code from a plurality of stages to a digitally controlled oscillator; and a frequency locked loop configured to (a) generate a second code to the digitally controlled oscillator over a slow-propagation path, and (2) disable the fast-propagation path to the digitally controlled oscillator upon the first code satisfying a match with the second code.
