PMU-Side Electromigration Control

This abstract first appeared for US patent application 20240427391 titled 'PMU-Side Electromigration Control

Original Abstract Submitted

techniques are disclosed relating to electromigration control implemented by a power management unit. in some embodiments, the power management unit itself is configured to monitor operating conditions, implement control for one or more electromigration loops, and send reduction alerts, via an inter-chip interconnect, to the processor circuitry it powers. in some embodiments, the power management unit implements both thermal and electromigration control loops. disclosed techniques may advantageously reduce or avoid electromigration issues, potentially with reduced impact on processor performance relative to traditional techniques.
