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

152 Merisc is the family name for a range of AVR32-based boards.
153
154 The boards are designed to be used in a man-machine
155 interfacing environment, utilizing a touch-based graphical
156 user interface. They host a vast range of I/O peripherals as
157 well as a large SDRAM & Flash memory bank.
