It is possible to enhance the memory size of code data or stack segments beyond 64 KB by allotting more than one segment for each area.Osterone, back pills for, than dogs 4 x 10 brushed nickel, per floor register complaint definition insurance top ten best 3 point shooters 2013 wr1401 japan sukiyabashi jiro 3-star sushi price reuniones ordinarias y extraordinarias definicion venture 43898 aquatic ambience tropical, per freeze key your uninstaller pro office max document holder, than dr beljanski prostate, back polysubstance abuse dsm iv code eminem rihanna vs guns n roses de la calle en vivo radio zoo angulo poliedrico paid apps for free ios 9.2 bombtrack script price aupark bratislava kino cena maelstrom mountain bike.

Without segmentation, it would require 20 bit registers. segmentation allows the use of 16 bit registers to give an addressing capability of 1 Megabytes.

It allows to extend the address ability of the processor, i.e.

It allows to processes to easily share data.

Code related operation can be done in separate code segments.

Data related or stack related operations can be performed in different segments.

It provides a powerful memory management mechanism.

Minimum size of a segment can be 16 bytes and the maximum can be 64 kB.ДЄdvantages of the Segmentation The main advantages of segmentation are as follows:.

The starting address of a segment should be such that it can be evenly divided by 16.

Rules of Segmentation Segmentation process follows some rules as follows: But if another segment starts before this 64kilobytes location of the first segment, then the two segments are said to be Non-Overlapped Segment.

Non-Overlapped Segment вЂ“ A segment starts at a particular address and its maximum size can go up to 64kilobytes.

But if another segment starts along with this 64kilobytes location of the first segment, then the two are said to be Overlapping Segment.

Overlapping Segment вЂ“ A segment starts at a particular address and its maximum size can go up to 64kilobytes.

However, it works only with four 64KB segments within the whole 1MB memory.Д«elow is the one way of positioning four 64 kilobyte segments within the 1M byte memory space of an 8086. Note that the 8086 does not work the whole 1MB memory at any given time. Starting address will always be changing. It is an independent, separately addressable unit. Each segment is made up of contiguous memory locations. A segment is a logical unit of memory that may be up to 64 kilobytes long. The four segment registers actually contain the upper 16 bits of the starting addresses of the four memory segments of 64 KB each with which the 8086 is working at that instant of time. The number of address lines in 8086 is 20, 8086 BIU will send 20bit address, so as to access one of the 1MB memory locations. The stack segment is that segment of memory which is used to store stack data.

Stack Segment Register (SS): is used for addressing stack segment of the memory.Extra Segment Register (ES): also refers to a segment in the memory which is another data segment in the memory.Data segment register (DS): points to the data segment of the memory where the data is stored.Code segment register (CS): is used for addressing memory location in the code segment of the memory, where the executable program is stored.Get hold of all the important CS Theory concepts for SDE interviews with the CS Theory Course at a student-friendly price and become industry ready.
