  10           AVR32 is a high-performance 32-bit RISC microprocessor core,
  11           designed for cost-sensitive embedded applications, with particular
  12           emphasis on low power consumption and high code density.
  13
  14           There is an AVR32 Linux project with a web page at

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

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