•The 8086 microprocessor has a much more powerful instruction set along with the architectural developments which imparts substantial programming flexibility and improvement in speed over the 8-bit microprocessor • The peripheral chips designed earlier for 8085 were compatible with microprocessor 8086 with slight

How many segments are in an 8086 microprocessor?

There are four segments used in 8086, code segment, data segment, stack segment and extra segment. Segment registers are used to contain the base addresses of the above mentioned segments. They are 16 bit registers. How much memory is present in an 8086 microprocessor? It depends on your definition of memory.

What is the function of segment register in microprocessor?

It holds the addresses of instructions and data in memory, which are used by the processor to access memory locations. It also contains 1 pointer register IP, which holds the address of the next instruction to executed by the EU. What are the segment registers are present in 8086 microprocessor?

How to load a data into a segment register in 8086?

In 8086 assembly programming, we can only load a data into a segment register by, first loading it into a general purpose register and then we have to move it from this general register to the segment register. Why can't we load it directly? Is there any special reason for not being allowed?

What are the advantages of segmentation in 8086?

The added advantage of segmentation is that it solves the problem of overriding. 8086 is divided into 4 segments i.e. Code, Stack, Data and Extra segment. Now when the data will be stored in code segment it will be in sequential order from 0000 to FFFF. The stack segment will be stored in the last in first out order.
