  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.
  24
  25           There is an AVR32 Linux project with a web page at
  26           http://avr32linux.org/.

 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.

 145           Merisc is the family name for a range of AVR32-based boards.
 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.
