DYNAMIC SWITCHING OF VOLTAGE REGULATORS IN A MULTIPROCESSOR SYSTEM

摘要

A switch interconnect is dynamically controlled at runtime to connect power sources to processing units in a multiprocessor system. Each power source is shareable by the processing units and each processing unit has a required voltage for processing a workload. When a system condition is detected at runtime, the switch interconnect is controlled to change a connection between at least one processing unit and a shared power source to maximize power efficiency. The shared power source is one of the power sources that supports multiple processing units having different required voltages.
