Nvidia patents flexible power system that moves energy between chips
Nvidia describes a power management system that can dynamically assign electrical power channels to different parts of a computer chip. Instead of having fixed power lines, the system uses a switch matrix to move power resources to where they are needed most.
In the filing’s own words
Technologies directed to allocating and reallocating phases across independent voltage rails for multiple circuits are described. A multi-phase voltage regulator (VR) module with multiple output rails can include multiple VR controllers, multiple phases, an output switch matrix, and phase allocation logic. The phase allocation logic, using the output switch matrix, can selectively allocate and reallocate any combination of the multiple phases to one of the multiple VR controllers to provide an output power on one of the multiple output rails.
What exactly they claim (claim 1)
1. A voltage regulator (VR) circuit comprising: a set of N output rails, where N is a positive integer greater than one; a set of N VR controllers; a set of M phases, where M is a positive integer greater than one, wherein each phase of the set of M phases comprises i) power components to regulate an output voltage and provide an output current, and ii) an N:1 input multiplexer to selectively couple the respective phase of the set of M phases to one of the set of N VR controllers; an output switch matrix coupled to the set of M phases and the set of N output rails; and supervisor logic coupled to the output switch matrix, the set of M phases, and the set of N VR controllers, wherein the supervisor logic is to selectively couple any one or more phases of the set of M phases to any one or more output rails of the set of N output rails.
