 What is CRIS ?
 --------------
 
-CRIS is an acronym for 'Code Reduced Instruction Set'. It is the CPU architecture in Axis
-Communication AB's range of embedded network CPU's, called ETRAX. The latest CPU is called
-ETRAX 100LX, where LX stands for 'Linux' because the chip was designed to be a good host for
-the Linux operating system.
