  18           AVR32 is a high-performance 32-bit RISC microprocessor core,
  19           designed for cost-sensitive embedded applications, with particular
  20           emphasis on low power consumption and high code density.
  21
  22           There is an AVR32 Linux project with a web page at
  23           http://avr32linux.org/.

 125           The Hammerhead platform is built around an AVR32 32-bit microcontroller from Atmel.
 126           It offers versatile peripherals, such as ethernet, usb device, usb host etc.
 127
 128           The board also incorporates a power supply and is a Power over Ethernet (PoE) Powered
 129           Device (PD).
 130
 131           Additionally, a Cyclone III FPGA from Altera is integrated on the board. The FPGA is
 132           mapped into the 32-bit AVR memory bus. The FPGA offers two DDR2 SDRAM interfaces, which
 133           will cover even the most exceptional need of memory bandwidth. Together with the onboard
 134           video decoder the board is ready for video processing.

 146           Merisc is the family name for a range of AVR32-based boards.
 147
 148           The boards are designed to be used in a man-machine
 149           interfacing environment, utilizing a touch-based graphical
 150           user interface. They host a vast range of I/O peripherals as
 151           well as a large SDRAM & Flash memory bank.
