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

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

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