In this paper, in studying absolute Angle measurement principle basis designed coding rules of a Single-ringcode and formulated the appropriate software algorithm.
Kernel space is flagged in the page tables as exclusive to privileged code (ring 2 or lower), hence a page fault is triggered if user-mode programs try to touch it.
