Question

Describe in detail the structure of Liner Memory Model and Segment Memory Models. Also write the three processors names for each memory models

Answer 1

Answer:

Microprocessor

Prerequisite – Segmentation

Segmentation is the process in which the main memory of the computer is logically divided into different segments and each segment has its own base address. It is basically used to enhance the speed of execution of the computer system, so that the processor is able to fetch and execute the data from the memory easily and fast.

Need for Segmentation –

The Bus Interface Unit (BIU) contains four 16 bit special purpose registers (mentioned below) called as Segment Registers.

Code segment register (CS): is used for addressing memory location in the code segment of the memory, where the executable program is stored.

Data segment register (DS): points to the data segment of the memory where the data is stored.

Extra Segment Register (ES): also refers to a segment in the memory which is another data segment in the memory.

Stack Segment Register (SS): is used for addressing stack segment of the memory. The stack segment is that segment of memory which is used to store stack data.
