	  AVR32 is a high-performance 32-bit RISC microprocessor core,
	  designed for cost-sensitive embedded applications, with particular
	  emphasis on low power consumption and high code density.

	  There is an AVR32 Linux project with a web page at
	  http://avr32linux.org/.

	  The Hammerhead platform is built around an AVR32 32-bit microcontroller from Atmel.
	  It offers versatile peripherals, such as ethernet, usb device, usb host etc.

	  The board also incorporates a power supply and is a Power over Ethernet (PoE) Powered
	  Device (PD).

	  Additionally, a Cyclone III FPGA from Altera is integrated on the board. The FPGA is
	  mapped into the 32-bit AVR memory bus. The FPGA offers two DDR2 SDRAM interfaces, which
	  will cover even the most exceptional need of memory bandwidth. Together with the onboard
	  video decoder the board is ready for video processing.

	  Merisc is the family name for a range of AVR32-based boards.

	  The boards are designed to be used in a man-machine
	  interfacing environment, utilizing a touch-based graphical
	  user interface. They host a vast range of I/O peripherals as
	  well as a large SDRAM & Flash memory bank.
