PstandbyP_{\mathrm{standby}}

What this part means

the power drawn the rest of the time.

Its job in the formula

PsP_standby is a part of this expression. Its role is fixed by the surrounding article and by the operations shown in the formula.

Where the article explains it

where D is the fraction of time spent actively computing and PstandbyP_{\mathrm{standby}} is the power drawn the rest of the time.

The passage around this formula

where D is the fraction of time spent actively computing and PstandbyP_{\mathrm{standby}} is the power drawn the rest of the time. For a keyword detector or a vibration monitor, D is typically small and falling, so Pˉ\bar{P} is dominated by PstandbyP_{\mathrm{standby}} almost regardless of how fast the active phase runs — which is exactly why this category optimises the idle floor first and peak throughput second, the opposite priority from a dedicated accelerator sized for a known, recurring, higher-duty workload.
