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

124 The Hammerhead platform is built around an AVR32 32-bit microcontroller from Atmel.
125 It offers versatile peripherals, such as ethernet, usb device, usb host etc.
126
127 The board also incorporates a power supply and is a Power over Ethernet (PoE) Powered
128 Device (PD).
129
130 Additionally, a Cyclone III FPGA from Altera is integrated on the board. The FPGA is
131 mapped into the 32-bit AVR memory bus. The FPGA offers two DDR2 SDRAM interfaces, which
132 will cover even the most exceptional need of memory bandwidth. Together with the onboard
133 video decoder the board is ready for video processing.

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