MINIX is a tiny OS kernel originally for teaching purpose. The well known presently popular OS, Linux, is extended from right this OS kernel of MINIX. The most valuable one of MINIX feature is the application for embedded system. Nowadays the development of SOC is full of vitality and it might someday integrate the MINIX with creative application. SOC is shorten from System On Chip. It implies that hardware cannot hold without a system so studying, developing and broadcasting the design of a fine and simple system is as important as designing a mature hardware. MINIX has well designed architecture and can be elastically extended for any application if anything is wanted to carry out. But orginal MINIX is only designed for INTEL x86 CPU. It should be more extensively extended to more environments. ARM is nowadays popular CPU on the world and this gives our a worthy studying to port MINIX to ARM. Surely during and after porting we found a lot of circumstances that can help and give other evelopers useful information and methods to carry on farther studying and improvement.
