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

 140           The Hammerhead platform is built around an AVR32 32-bit microcontroller from Atmel.
 141           It offers versatile peripherals, such as ethernet, usb device, usb host etc.
 142
 143           The board also incorporates a power supply and is a Power over Ethernet (PoE) Powered
 144           Device (PD).
 145
 146           Additionally, a Cyclone III FPGA from Altera is integrated on the board. The FPGA is
 147           mapped into the 32-bit AVR memory bus. The FPGA offers two DDR2 SDRAM interfaces, which
 148           will cover even the most exceptional need of memory bandwidth. Together with the onboard
 149           video decoder the board is ready for video processing.

 161           Merisc is the family name for a range of AVR32-based boards.
 162
 163           The boards are designed to be used in a man-machine
 164           interfacing environment, utilizing a touch-based graphical
 165           user interface. They host a vast range of I/O peripherals as
 166           well as a large SDRAM & Flash memory bank.
