Abstract

See full text

An example method can include performing a first sensing operation associated with circuitry on a system on chip (SoC) to determine a first data value, performing a second sensing operation associated with circuitry of a sensor the SoC to determine a second data value, responsive to the first data value and the second data value being the same data value, determining that a clock margin is sufficient, and responsive to the first data value and the second data value being different data values, determining that a clock margin is insufficient. In some examples, a voltage-frequency operating combination associated with at least one operation of the SoC can be adjusted to a particular stored voltage-frequency operating combination that provides a sufficient clocking margin.
