■μT-Kernel 

μT-Kernel is a T-Kernel for small embedded systems. It is designed so that performance can be maximized even in environments with small resources, like 16-bit single chip microcomputers.

For this reason, reference μT-Kernel source code was released with more relaxed terms of use ( μT-License) than the regular license for T-Kernel with regard to the distribution of modification. Redistribution of μT-Kernel is permitted after porting it to their systems by manufacturers and vendors as needed.
Since T-Kernel and μT-Kernel are highly compatible, if functions common to both OSs are used, mutual porting of applications to either OSs essentially only involves
recompiling the source code.
