This document provides an overview of microprocessors. It discusses that a microprocessor is a clock driven semiconductor device manufactured using LSI or VLSI techniques. It can be divided into an arithmetic logic unit, register array, and control unit. Memory stores binary instructions and data for the microprocessor. Input/output devices allow communication with external components via a system bus. The document also discusses microprocessor architecture, languages like assembly and machine code, and provides details on the 8085 microprocessor from Intel including its address bus, data bus and control bus.

3. What is Microprocessor
 Microprocessor is
a clock driven
semi conductor
device,
manufacture by
using either LSI or
VLSI techniques.

4. The Microprocessor can divided into three segments
Arithmetic logic unit
Register Array
Control Unit
 Memory: The memory store the binary information as
instruction & data, and provide the information to the
microprocessor whenever necessary.
 I/O(Input / Output): The I/O device is a microprocessor
based system, it communicates with the outside world.
 System Bus: It is the communication path between the
microprocessor and peripherals.

5. Language
High level language: Programming language that are to be
machine independent are called high level language.
Example:
BASIC, PASCAL, C, C++
Assembly Language: Assembly language is a low level
programming language. It is difficult to write program by using 0 & 1. The
computer manufactures have devised English like word to represent the
binary instruction of a machine, this is assembly language.
 Machine Language: Microprocessor recognize in binary
numbers. Each machine has it’s own binary words meaning &
language called machine language.
 Low level language:

6. Microprocessor Architecture
 The microprocessor is a programmable digital device
designed with registers, flip-flops, and timing elements . The
microprocessor has a set of instructions designed internally
to manipulate data with peripherals (I/O). The process of
data manipulation and communication is determine by the
logic design of the microprocessor called architecture.
 Microprocessor Architecture functions can be
classified into three general categories.
 Microprocessor initiated operation
 Internal operation
 Peripheral or external initiated operation

7. 8085 Microprocessor
The 8085 Microprocessor is an 8 bit Microprocessor
produce by Intel and introduce in 1976.
8085 BUS
 ADDRES BUS: It is a group of 16 lines, generally identified as A0 to
A15. The ADDRES BUS is unidirectional that is the bit flow in one
direction from MPU to peripherals.
 DATA BUS: The DATA BUS is a group of 8 lines use for data flow,
usually this lines are bi-directional that is data flow in both directions
between the Microprocessor & memory & peripherals.
 CONTROL BUS: The control bus is comprised of various singles lines
that carry synchronizing signals. The Microprocessor uses such lines
to perform the third function that is providing timing signals.
 The 8085 uses three separate BUSes to perform its
operations
