Abstract: Systems and methods for coordinating performance parameters in multiple domains are described. In an embodiment, a method includes receiving a request to change a state of an electronic circuit, where the circuit includes a first domain and a second domain, causing a first parameter of a first circuit serving the first domain to be modified to a first modified parameter based on the request, and causing a second parameter of a second circuit serving the second domain to be modified to a second modified parameter based on the request. In some cases, a parameter may include a clock frequency. In other cases, a parameter may include a voltage. In some embodiments, a system may be implemented as a logic circuit and/or as a system-on-a-chip (SoC). Devices suitable for using these systems include, for example, desktop and laptop computers, tablets, network appliances, mobile phones, personal digital assistants, e-book readers, televisions, and game consoles.
