 21           AVR32 is a high-performance 32-bit RISC microprocessor core,
 22           designed for cost-sensitive embedded applications, with particular
 23           emphasis on low power consumption and high code density.

124           The Hammerhead platform is built around an AVR32 32-bit microcontroller from Atmel.
125           It offers versatile peripherals, such as ethernet, usb device, usb host etc.
126 
127           The board also incorporates a power supply and is a Power over Ethernet (PoE) Powered
128           Device (PD).
129 
130           Additionally, a Cyclone III FPGA from Altera is integrated on the board. The FPGA is
131           mapped into the 32-bit AVR memory bus. The FPGA offers two DDR2 SDRAM interfaces, which
132           will cover even the most exceptional need of memory bandwidth. Together with the onboard
133           video decoder the board is ready for video processing.

146 
147           The boards are designed to be used in a man-machine
148           interfacing environment, utilizing a touch-based graphical
149           user interface. They host a vast range of I/O peripherals as
150           well as a large SDRAM & Flash memory bank.
