Robust and system reset commands system call- be carried out by a processor, in order to control between a requesting location and to transmit a operating system kernel.

The execution circuit receives a system call instruction from a requesting area, in order to the control of a first level of privilege of the requesting location for a second level of privilege to transmit a operating system kernel. As a reaction change of the execution circuit the data structures, on which the register, between said requesting location and the operating system kernel in an undivided transition.
