We’ve railed on this before … it is irritating that almost every embedded device has to come with its own unique wall-plug charger. I mean, why do we go to such trouble to take standard power out of the wall and make it into nonstandard power for a device? If a power connector could be standardized and the power could be set up intelligently, the “universal charger” would be a lot closer to reality.

Green Plug is partnering with Imagination Technologies to implement its Greentalk technology in new chips and processors based on Imagination’s IP that enable consumer electronic devices to exchange power information through the power line between power adapters and electronic products.

Green Plug will develop two new products using Imagination’s IP: the next-generation Green Plug Power Processor (GPP) chip for power supplies and the Greentalk Load Processor (GLP) macro for consumer electronic devices. With GLP, devices can communicate with Greentalk-enabled power supplies directly over the existing power cable and connector on the device.
