Addressing mode is the way of addressing a memory location in instruction. Microcontroller needs data or operands on which the operation is to be performed. The method of specifying source of operand and output of result in an instruction is known as addressing mode.
There are various methods of giving source and destination address in instruction, thus there are various types of Addressing Modes. Here you will find the different types of Addressing Modes that are supported in Micro Controller 8051. Types of Addressing Modes are explained below:
1.Register Addressing Mode
2.Direct Addressing Mode
3.Register Indirect Addressing Mode
4.Immediate Addressing Mode
5.Index Addressing Mode
Explanation:
Register Addressing Mode: In this addressing mode, the source of data or destination of result is Register. In this type of addressing mode the name of the register is given in the instruction where the data to be read or result is to be stored.
Example: ADD A, R5 ( The instruction will do the addition of data in Accumulator with data in register R5)
Direct Addressing Mode: In this type of Addressing Mode, the address of data to be read is directly given in the instruction. In case, for storing result the address given in instruction is used to store the result.
Example: MOV A, 46H ( This instruction will move the contents of memory location 46H to Accumulator)
Register Indirect Addressing Mode: In Register Indirect Addressing Mode, as its name suggests the data is read or stored in register indirectly. That is, we provide the register in the instruction, in which the address of the other register is stored or which points to other register where data is stored or to be stored.
Example: MOV A, @R0 ( This instruction will move the data to accumulator from the register whose address is stored in register R0 ).

Immediate Addressing Mode : In Immediate Addressing Mode , the data immediately follows the instruction. This means that data to be used is already given in the instruction itself.
Example: MOV A, #25H ( This instruction will move the data 25H to Accumulator. The # sign shows that preceding term is data, not the address.)
Index Addressing Mode: Offset is added to the base index register to form the effective address if the memory location.This Addressing Mode is used for reading lookup tables in Program Memory. The Address of the exact location of the table is formed by adding the Accumulator Data to the base pointer.
Example: MOVC, @A+DPTR ( This instruction will move the data from the memory to Accumulator; the address is made by adding the contents of Accumulator and Data Pointer.

Using a circularly-linked list made the solution trivial. The solution would have been more difficult if an array had been used. This illustrates the fact that the choice of the appropriate data structures can significantly simplify an algorithm. It can make the algorithm much faster and efficient.

A computer network or data network is a telecommunications network which allows computers to exchange data. In computer networks, networked computing devices exchange data with each other using a data link. The connections between nodes are established using either cable media or wireless media.
virtualization is the concept of separating the logical desktop from the physical machine. One form of desktop virtualization, virtual desktop infrastructure (VDI), can be thought of as a more advanced form of hardware virtualization.
OSI layers describes how the data can be send from one parties to another during data communication. it also gives the detailed information of how the data functionally divided into small pieces and reaches the destination.
pipelining is the concept of decomposing the sequential process into number of small stages in which each stage execute individual parts of instruction life cycle inside the processor.
hardwired control is the system level communication in which how the control signal generate by processor with the help of conditional codes, external output and counter circuits
interrupt is a concept of solution of better cpu utilization. when the more routine is happening inside the processor then how it should technically share the resource without interruption.
This PPT describe the use of direct memory access and how the input and output devices exchange the data with processor without interruption like waiting for address fetch.

2. A computer often need to perform a particular
subtask using the familiar subroutine structure.
In order to maintain information and linkage
between main program and subroutine, a data
structure called stack is used.
4. STACK
A stack is a list of data elements, usually
words or bytes, with accessing restriction
that elements can be added (or) removed at
one end of the list is called top of the stack.
Other end is called bottom of the stack.
The structure is sometimes referred to as a
pushdown stack.
6. Another descriptive
LIFO-the last data placed on the stack is the
first one removed when retrieval begins.
Push & Pop- used to placing a new item on
the stack and removing the top item from the
stack.
7. Assume data stored in stack
First element is placed in location
BOTTOM, when new elements are pushed
onto the stack, they are store successive
lower address locations.
We use a stack that grows in the direction of
decreasing memory addresses.
8. example
Stack of word items in the memory of a
computer.
It contain numerical values, with 43 at the
bottom and -28 at the top.
SP- A processor register point the top of the
stack.
32 bit word length and byte addressable.
9.
10. Push operation
Subtract #4, SP
Move NEWITEM, (SP)
The subtract instruction subtracts the source operand 4
from the destination operand contained in SP and place
the result in SP.
These two instructions move the word from location
NEWITEM onto the top of the stack, by decrementing
the stack pointer by 4 before the move.
11.
12. POP operation
Move (SP), ITEM
Add #4,SP
These two instruction move the top value
from stack into location ITEM and then
increment the stack pointer by 4, now SP
point to the new top element.
13. Auto increment or decrement
Move NEWITEM, -(SP) -Push operation
Move (SP)+, ITEM - POP operation
14. concept
When stack is used in a program, it is
usually allocated a fixed amount of space in
the memory.
We must avoid push an item onto the stack
when the stack has reached its max size.
We also avoid pop an item when the stack
off an empty stack.
Which could result from a programming
error.
15. example
Stack runs from location – 2000(Bottom)
And no further than location 1500
Recall that SP is decremented by 4 before
new data are stored on the stack.
Hence, an initial value of 2004 means that
the first item pushed onto the stack will be at
location 2000.
