  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.

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