Real-time mode: The addressing adopts the same 16-bit segment and offset as 8086. The maximum addressing space is 1 MB and the maximum segment is 64 KB. You can use 32-bit commands. 32-bit x86 CPU is used for high-speed 8086. Protection Mode: 32-bit segments and offsets are used for addressing. The maximum addressing space is 4 GB and the maximum segment is 4 GB (Pentium pre and 64 GB later ). In the protected mode, the CPU can enter the virtual 8086 mode, which is the environment for running th
