  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.

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

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