10 AVR32 is a high-performance 32-bit RISC microprocessor core,
11 designed for cost-sensitive embedded applications, with particular
12 emphasis on low power consumption and high code density.
14 There is an AVR32 Linux project with a web page at
15 http://avr32linux.org/.

130 The Hammerhead platform is built around an AVR32 32-bit microcontroller from Atmel.
131 It offers versatile peripherals, such as ethernet, usb device, usb host etc.
133 The board also incorporates a power supply and is a Power over Ethernet (PoE) Powered
136 Additionally, 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.

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