The Green Load Processor (GLP) is a hardware and software protocol stack that exists in existing processors on the load device. It is licensed free of charge to strategic partners and has no increase in BOM cost for products that enable smart power since the GLP is most often embedded in an existing chip on the load. Green Plug can also be implemented as a macro for System-on-Chip technology.  The GLP can notify the GPP of changing power needs, such as higher or lower voltage or to shut off completely, to reduce energy consumption in low-load and no-load operating conditions.
