FREQUENCY OVERSHOOT AND VOLTAGE DROOP MITIGATION APPARATUS AND METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18514807 titled 'FREQUENCY OVERSHOOT AND VOLTAGE DROOP MITIGATION APPARATUS AND METHOD
Simplified Explanation
The patent application describes an apparatus and method for requesting a temporary supply voltage and/or current boost prior to an event that could result in frequency overshoot, allowing for on-the-fly changes in supply voltage and clock frequency for a processor with minimal impact on Vmin.
- The apparatus sends a signal to a voltage regulator or generator requesting a temporary supply voltage and/or current boost before a potential frequency overshoot event.
- This enables a clocking source, such as a phase locked loop (PLL), to lock fast without needing long-term voltage guard bands.
- The temporary boost in supply voltage allows for absorbing the impact of clock frequency overshoot, with the voltage level being reduced back to the expected level afterwards in a step-wise fashion to avoid undershoot.
Potential Applications
This technology could be applied in:
- High-performance computing systems
- Mobile devices
- Internet of Things (IoT) devices
Problems Solved
This technology addresses the following issues:
- Frequency overshoot in processors
- Impact on Vmin during clock frequency changes

Original Abstract Submitted
An apparatus and method are described, which prior to an event that could result in frequency overshoot, sends a signal to a voltage regulator or generator requesting a temporary supply voltage and/or current boost. This enables a clocking source, such as a phase locked loop (PLL) to lock fast while not needing any long-term voltage guard bands. The apparatus and scheme allows for on-the-fly change in supply voltage and/or clock frequency for a processor with little to no impact on Vmin. During the clock frequency overshoot, the supply voltage is temporarily boosted and then reduced down to the expected voltage level of the power supply. Such boost allows for absorbing the clock frequency overshoot impact. The supply voltage level can be reduced in a step-wise fashion to avoid any potential undershoot in clock frequency.
