A processor including logic to execute an instruction to synchronize a mapping from a physical address of a guest of a virtualization based system to a physical address of the host of the virtualization based system, and stored in a translation lookaside buffer, with a corresponding mapping stored in an extended paging table of the virtualization based system. Overlapping sheets which pass the first and second separation units and are not separated are detected to be overlapped in a state that they are clamped by the nip of the drawing roller and pinch roller. Also, the signal-to-noise ratio at an intended receiver is maintained above a predetermined minimum SNR, for instance above 5 dB.
