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

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

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