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