Long description

The figure consists of two vertical blocks and two horizontal blocks. A horizontal dotted line is passing through the mid of these three vertical blocks which divides the blocks into two parts. The first vertical block is labeled Normal Mode (V T L 0), the upper part of the block is consist of one sub-block which is labeled Normal mode process and the lower part of the block is consist of two sub-blocks labeled N T O S Normal kernel and Drivers. The second vertical block is labeled Secure Mode (V T L 1), the upper part of the block is consist of one sub-block labeled Trustlets and the lower part of the block is consist of one sub-block labeled Secure Kernel. The horizontal block is labeled Hypervisor which is divided into two sub-blocks and labeled V T L 0 S L A and VTL1 SLAT. Another horizontal block is divided into three sub-blocks which are labeled CPU, Memory, I bar O Devices.
