I've some doubt:
In embedded environment, the system is very
proprietary, so, the difference between "kernel state" and "user
state" is of none sense(all task may run in kernel state always), and
switch between the two process state is not necessary for
efficiency.
In communication device such as ATM and
mutilayer switch, which is the more suitable environment for the software
development, the rt-linux and the commercial rtos such as psos and
vxworks?
