ABSTRACT:
The brain or engine of the PC is the processor (sometimes called microprocessor), or central
processing unit (CPU). The CPU performs the system’s calculating and processing. The processor is
easily the most expensive single component in the system, costing up to four or more times greater
than the motherboard it plugs into. Intel is generally credited with creating the first microprocessor in
1971 with the introduction of a chip called the 4004. Today Intel still has control over the processor
market, at least for PC systems. This means that all PC-compatible systems use either Intel
processors or Intel-compatible processors from a handful of competitors (such as AMD or Cyrix).
Intel’s dominance in the processor market had not always been assured. It is generally credited
with inventing the processor. It is interesting to note that the microprocessor had only existed for 10
years prior to the creation of the PC! The microprocessor was invented by Intel in 1971. The PC was
created by IBM in 1981. Now nearly 20 years later, we are still using systems based more or less on
the design of that first PC (and mostly backward compatible with it). The processors powering our
PCs today are still backward compatible in many ways with the 8088 selected by IBM in 1981.
Processors can be identified by two main parameters: how wide they are and how fast they are. The
speed of a processor is a fairly simple concept. Speed is counted in megahertz (MHz), which means
millions of cycles per second—and faster is better! The width of a processor is a little more
complicated to discuss because there are three main specifications in a processor that are expressed in
width. They are
l. Internal registers
2. Data input and output bus
3. Memory address bus
Systems below 16MHz usually had no cache memory at all. Starting with 16MHz systems, high-
speed cache memory appeared on the motherboard because the main memory at the time could not
run at 16MHz.
Microprocessors are mainly found in 4, 8, 16, 20, 32, 64-bit configuration. Many embedded uses of
4-bit and 8-bit microprocessors, such as terminals, printers, various kinds of automation etc., followed soon
after. Affordable 8-bit microprocessors with 16-bit addressing also led to the first general-purpose
microcomputers from the mid-1970s on.
Thousands of items that were traditionally not computer-related include microprocessors. These include large
and small household appliances, cars (and their accessory equipment units), car keys, tools and test
instruments, toys, light switches/dimmers and electrical circuit breakers, smoke alarms, battery packs, and hi-fi
audio/visual components (from DVD players to phonograph turntables). Such products as cellular
telephones, DVD video system and HDTV broadcast systems fundamentally require consumer devices with
powerful, low-cost, microprocessors.

INTRODUCTION:-
If we take a look around us, we would be sure to find a device that uses a microprocessor in some
form or the other. Microprocessors have become a part of our daily lives and it would be difficult to
imagine life without them today. From digital wrist watches, to pocket calculators, from microwaves,
to cars, toys, security systems, navigation, to credit cards, microprocessors are ubiquitous. All this
has been made possible by remarkable developments in semiconductor technology enabling in the
last 30 years, enabling the implementation of ideas that were previously beyond the average
computer architect’s grasp.
The basic evolution in microprocessor was came in to known with the invention of Intel 4004,
The 4004 processor was introduced on November 15, 1971, and originally ran at a clock speed of
108KHz (108,000 cycles per second, or just over one-tenth a megahertz). The 4004 contained 2,300
transistors and was built on a 10 micron process. And then in April 1972, Intel released the 8008
processor, after this various 8-bit, 16-bit, 32-bit, 64-bit and various dual core Pentium, Celeron
processors. But there is a big question.
What was before microprocessor??
We will also come to learn this thing in our syllabus. We will start our discussion with mechanical
age, followed by 1st, 2nd, 3rd and present generation.
I have said lot of things regarding microprocessor and its evolution but beginners have a lot of
questions which are related to basics of microprocessor, they also have various questions like – what
is microprocessor ?, what is the difference between microprocessor and microcontroller? How
many types of memory exist? How microprocessor’s programming is done? And a lot of questions,
queries.
So we will also cover some of these questions, some in detail and some in brief, depending upon
the requirements. While discussing regarding evolution we will restrict ourselves to some Intel’s
microprocessors including Pentium series, Celeron series etc. and will touch to some of the
processors which are being produce by AMD, it is because only if we look around us we will found
most are Intel processor, mostly used in laptops like i3, i5, i7 processor. AMD processors are also
seen in the market.

Microprocessor
A microprocessor incorporates the functions of a computer's central processing unit (CPU) on a
single integrated circuit (IC) or at most a few integrated circuits. All modern CPUs are
microprocessors making the micro- prefix redundant.
Definition- The microprocessor is a multipurpose, programmable device that accepts digital data as
input, processes it according to instructions stored in its memory, and provides results as output.
It is an example of sequential digital logic, as it has internal memory. Microprocessors operate on
numbers and symbols represented in the binary numeral system.
The advent of low-cost computers on integrated circuits has transformed modern society. General-
purpose microprocessors in personal computers are used for computation, text editing, multimedia
display, and communication over the Internet. Many more microprocessors are part of embedded
systems, providing digital control over myriad objects from appliances to automobiles to cellular
phones and industrial process control.
In the NASA Apollo space missions to the moon in the 1960s and 1970s, all onboard computations
for primary guidance, navigation and control were provided by a small custom processor called
"The Apollo Guidance Computer". It used wire wrap circuit boards whose only logic
elements neither were three-input NOR gates.[1]
The integration of a whole CPU onto a single chip or on a few chips greatly reduced the cost of
processing power. The integrated circuit processor was produced in large numbers by highly
automated processes, so unit cost was low. Single-chip processors increase reliability as there are
many fewer electrical connections to fail. As microprocessor designs get faster, the cost of
manufacturing a chip (with smaller components built on a semiconductor chip the same size)
generally stays the same.
Microprocessors integrated into one or a few large-scale ICs the architectures that had previously
been implemented using many medium- and small-scale integrated circuits. Continued increases in
microprocessor capacity have rendered other forms of computers almost completely obsolete
(see history of computing hardware), with one or more microprocessors used in everything from the
smallest embedded systems and handheld devices to the largest mainframes and supercomputers.
The first microprocessors emerged in the early 1970s and were used for electronic calculators,
using binary-coded decimal (BCD) arithmetic on 4-bit words. Other embedded uses of 4-bit and 8-bit
microprocessors, such as terminals, printers, various kinds of automation etc., followed soon after.
Affordable 8-bit microprocessors with 16-bit addressing also led to the first general-purpose
