  22           AVR32 is a high-performance 32-bit RISC microprocessor core,
  23           designed for cost-sensitive embedded applications, with particular
  24           emphasis on low power consumption and high code density.
  25
  26           There is an AVR32 Linux project with a web page at
  27           http://avr32linux.org/.

 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.
