Respected tech analysis site Digital Foundry has written an interesting article titled The Secrets of the Wii U GamePad. The Wii U GamePad has been reverse-engineered by the developers behind Dolphin. The team contacted developer Pierre Bourdon to find out more about the innovative device. The conclusion that the team came to is that the Wii U GamePad isn’t anywhere near as complex as the most basic Android powered tablet.
The GamePad itself isn’t anywhere near as complex as even the most basic Android tablet – essentially it’s a standard game controller, with a touch-screen and a WiFi card, paired up with a decoder chip for the incoming video stream. Controller inputs themselves are beamed back to the Wii U via the same WiFi channel (180 times per second no less), in contrast to the Bluetooth employed by the Wiimote.
