The ETRAX CRIS is a series of CPUs designed and manufactured by Axis Communications for use in embedded systems since 1993[1]. The name is an acronim of the chip's features: Ethernet, Token Ring, AXis - Code Reduced Instruction Set. Token ring support has been taken out from the latest chips as it has become obsolete.
