Adaptive voltage scaling (AVS): Processor's minimal operating voltages at a specific frequency vary because of the manufacturing process variation, AVS is thus implemented to adjust PMIC output voltage rail to match the processor. Even if processors operate at the same voltage and frequency, the power consumption will be different.
Dynamic voltage scaling (DVS): The higher the operating frequency, the better performance the processor has, as well as a higher power consumption. DVS adjusts output voltage level based upon the desired processing tasks to achieve the best performance or lowest power possible.
- With AVS, the processor will determine its minimal voltage required to operate at a specific frequency.
- On “Strong” processor silicon, this will significantly reduce power, even compared to “weak” silicon
- This will reduce power consumption and temperature, preventing thermal runaway during heavy workloads
- By providing the AVS software, this saves the customer time and money to develop and validate it themselves
