Combination of Control Interfaces for Multiple Communicating Domains
First Claim
1. A combiner for controlling a cross domain component in a system of two or more power domain controls, said combiner comprising:
- a first state for requesting cross domain component quiescence when a first control requests quiescence; and
a second state for ensuring cross domain component quiescence before accepting the first control quiescence request.

Abstract
Various implementations described herein are directed to a method and apparatus for a low power interface combiner for controlling a cross domain component in a system of two or more power domain controls. The combiner may include a first state for requesting cross domain component quiescence when a first control requests quiescence and a second state for ensuring cross domain component quiescence before accepting the first control quiescence request. The combiner may include a third state for requesting cross domain component quiescence exit when a last control requests quiescence exit and other controls have exited or are exiting quiescence. The combiner may include a fourth state for ensuring cross domain component quiescence exit before accepting the last control quiescence exit request.

17. A method for controlling a cross domain component in a system having two or more domain controls and the cross domain component in a quiescence state, said method comprising:
-
requesting cross domain component quiescence exit only when a last control requests quiescence exit and all other controls have exited or are exiting quiescence; and ensuring cross domain component quiescence exit before accepting the last control quiescence exit request.
