Qualcomm filed 1 patent in Hardware this month.
The application covers a PID controller-based system designed to stabilize frame rates in mobile gaming by dynamically adjusting CPU and GPU frequencies according to load ratios. This approach aims to maintain steady performance during gameplay through real-time frequency management.
Qualcomm's sole Hardware patent tackles the persistent challenge of maintaining smooth frame rates in mobile games through a control-theory approach borrowed from classical engineering. The system applies PID (proportional-integral-derivative) control logic to calculate frequency adjustments needed to stabilize gameplay at target frame rates, then distributes those corrections across different processor clusters based on how heavily each cluster is being utilized at that moment. Rather than applying blanket frequency changes to all cores or relying on predefined rules, the method accounts for the actual workload distribution between heterogeneous CPU and GPU clusters. This load-aware allocation of frequency adjustments differentiates the technique from conventional dynamic voltage and frequency scaling governors that typically treat cores more uniformly.
