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

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