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/.

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

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