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

 148           Merisc is the family name for a range of AVR32-based boards.
 149
 150           The boards are designed to be used in a man-machine
 151           interfacing environment, utilizing a touch-based graphical
 152           user interface. They host a vast range of I/O peripherals as
 153           well as a large SDRAM & Flash memory bank.
