The Green Power Processor (GPP) from Green Plug is an advanced System-on-Chip (SoC) that enables CE manufacturers to design digital power adapter architectures that save energy by facilitating communication between the power source and the connected device.

The GPP is based on the high-performance, low-power META MTP Core from Imagination Technologies Group plc (LSE:IMG). It offers CE power supply designers and developers two independent hardware threads, primarily single-cycle instructions, and a variety of advanced low-power features and optimizations for AC/DC and DC/DC power conversions.

GPP is a combination of mixed signal technology, multi-threaded hardware, advanced low-power features and optimizations that together provide a platform for rapid development of modern, efficient power supply designs.
“Indeed, the era of digital power has arrived,” said Frank P. Paniagua, Jr., founder and CEO of Green Plug. “Digital means smart, rendering antiquated and inflexible analog controllers for power supply designs obsolete. Digital means easy re-use of power supply designs for new products.”

The GPP is customizable to the power supply design by input parameter selection or fully custom code images. Feedback loops, switching frequencies and overload detection thresholds are adjustable by software, allowing a variable power supply to be designed with maximum output range and efficiency at each set point.

GPP also offers developers the ability to modify their power adapter designs in real time using embedded development tools, thereby significantly reducing development cycle time.

While the GPP provides control and communication on the power supply, another Green Plug innovation, the Green Load Processor (GLP), provides communication and functionality on the electronic device. When enabled along with Green Plug’s GreenTalk digital communication software and hardware protocol stack and GreenWire multi-function physical layer technology, manufacturers have the flexibility to offer power adapters that can communicate changes in power requirements, such as higher or lower voltage, or to shut off completely when not in use.

The GPP will be available in the second quarter of 2011.
