Microcontroller program architecture diagram code#

Oscillator: As the microcontroller is digital circuit therefore it needs timer for their operation. It is generally be used for transferring the data from one peripherals position to other peripherals.

Data bus: 8051 microcontroller is consisting of 8 bits data bus.

It is generally be used for transferring the data from Central Processing Unit to Memory.

Address Bus: 8051 microcontrollers is consisting of 16 bit address bus.

Let's see the two types of bus used in 8051 microcontroller: Therefore, a bus can bear 8 bits, 16 bits all together. The different bus configuration includes 8, 16 or more cables.

Microcontroller program architecture diagram code#

In microcontroller 8051 there is code or program memory of 4 KB that is it has 4 KB ROM and it also comprise of data memory (RAM) of 128 bytes.īus : Bus is a group of wires which uses as a communication canal or acts as means of data transfer. Microcontroller also required memory for storage of data and operands for the short duration. This program installed in microcontroller required some on chip memory for the storage of the program. This program guides the microcontroller to perform the specific tasks. Memory: For operation Micro-controller required a program. Let's see the five sources of interrupts in 8051 Microcontroller: Types of interrupt in 8051 Microcontroller:

Interrupts provide a method to postpone or delay the current process, performs a sub-routine task and then restart the standard program again. Interrupts: Interrupts is a sub-routine call that given by the microcontroller when some other program with high priority is request for acquiring the system buses the n interrupts occur in current running program. CPU manage the different types of registers available in 8051 microcontroller. It interprets the program stored in ROM and carries out from storage and then performs it projected duty. User has no power to control the functioning of CPU. It synchronizes and manages all processes that are carried out in microcontroller.

Let's see the internal architecture of 8051 Microcontroller represented in form of block diagram as shown below:īasic components present internally inside 8051 Microcontroller architecture are:ĬPU (Central Processing Unit): CPU act as a mind of any processing machine.
