abstract:Power processing units (PPUs) are circuit devices that convert an electricity input from a utility line into the appropriate voltage and current to be used for the device in question. They serve the same purpose as linear amplifiers, but they are much more efficient, since the use of linear amplifiers results in much power loss due to the use of a resistor to change the voltage and current.
The Japanese firm is pinning its hopes on the processingpower and storage capacity of its new console, which will include a revolutionary processingunit based on the new Cell chip, developed with IBM and Toshiba.
