Performance optimization in multi-domain systems on chips that share a power supply

A system-on-chip (SoC) performance management technique is described for designs with multiple clock domains sharing a power supply. The technique involves a shared rail boost (SRB) feature that adjusts performance states across different clock domains. The SRB feature is enabled based on conditions such as utilization levels, active core counts, or voltage differences between domains. When enabled, the SRB feature allows assignment of a higher performance state to a clock domain. The technique compares open-loop voltages between domains and aggregates target and recommended performance states to determine final states. It includes mechanisms for disabling the SRB feature under certain conditions and considers the performance states of other clock domains. The approach operates independently of schedulers or kernels, allowing for integration into various SoC designs.
