real mode and protected mode memory addressing in 8086

Only the 8086 and 8088 operate exclusively in the real mode. Real mode operation allows the microprocessor to address only the first 1M byte of memory space-address space is 65,536 bytes (64 kbytes), which is similar to. 8086 memory and I/O address space. Real Mode Programming Model. All real mode memory addresses must consist of a segment address plus an offset the 8086 is 20 bits wide (20 lines) i.e. the processor can access memory. May reside in one of the internal registers of the microprocessor. – May be stored at an address in memory. • Register Addressing Mode. – MOV AX, BX. Real mode operationallows the microprocessor to address only the first 1 Mbyte of memory.oEven though the 8086 has a 1 Mbyte address space, REAL MODE MEMORY ADDRESSING. The 80286 and above operate in either the real or protected mode. Only the 8086 and 8088 operate exclusively in the real mode.
