US 2026/0086624 A1 · PER-THREAD GROUP POWER LIMITER

Abstract

Some embodiments include a performance controller that can identify and selectively limit the power usage of one or more thread groups (TGs) corresponding to an application. Some embodiments include tracking power consumption (e.g., watts) of each TG. Examples of the power consumption can include central processing unit (CPU) power, neural engine (NE) power, dynamic random access memory (DRAM) power, and/or graphics processing unit (GPU) power. The tracked power metrics can be fed to a closed loop proportional-integral-derivate (PID) controller or limiter (e.g., a per-TG power limiter) that can converge the maximum power consumed by a given TG to a programmable threshold.

Dependent claims

A computing device, comprising:

a memory;
and
one or more processors communicatively coupled to the memory, wherein the one or more processors are configured to:
execute two or more applications each corresponding to a corresponding thread group (TG), wherein a corresponding first application TG of a first application of the two or more applications exceeds a target power threshold;
limit a power consumption of the corresponding first application TG;
and
assign the corresponding first application TG to a corresponding core type based at least on the limitation of the power consumption.
