15 | AVR32 is a high-performance 32-bit RISC microprocessor core, | |
16 | designed for cost-sensitive embedded applications, with particular | |
17 | emphasis on low power consumption and high code density. | |
18 | ||
19 | There is an AVR32 Linux project with a web page at | |
20 | http://avr32linux.org/. | |
