  19          AVR32 is a high-performance 32-bit RISC microprocessor core,
  20          designed for cost-sensitive embedded applications, with particular
  21          emphasis on low power consumption and high code density.
  22
  23          There is an AVR32 Linux project with a web page at
  24          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.
