  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
  15           http://avr32linux.org/.

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

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