US 2026/0154128 A1 · METHOD AND SYSTEM FOR PROVIDING A BANDWIDTH (BW) VOTE TO BUS CONTROL CIRCUITRY COUPLED TO ONE OR MORE SUBSYSTEMS PRESENT ON A SYSTEM-ON-CHIP (SOC)

Abstract

Systems and methods are provided for using subsystem metrics to dynamically adjust the bandwidth (BW) scaling factor used when voting for BW needs based on the BW of monitored traffic. For a CPU core, for example, it can be inefficient to use a static BW scaling factor when other core metrics provide extra information that can improve power consumption efficiency without degrading performance or user experience. Dynamically adjusting or selecting the BW scaling factor based on metrics is more efficient than using a static scaling factor and can result in greater efficiency in terms of achieving lower power consumption without degrading performance or user experience.

Dependent claims

A bandwidth (BW) voting logic coupled to one or more subsystems, the BW voting logic comprising:

a module configured to:
determine a BW usage of a communication bus coupled to the one or more subsystems;
determine a BW scaling factor based on one or more metrics of the one or more subsystems;
and
vote for a BW based on BW usage of the communication bus and the BW scaling factor.
