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

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

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