Basic Concepts of Microprocessors
A

Q
• Differences between:
A
3
Q
- Microcomputer- a computer with a
A
4
Q
microprocessor as its CPU. Includes memory
A
I/O
5
Q
etc.
A
6
Q
- Microprocessor – silicon chip which includes
A
7
Q
ALU
A
register circuits & control circuits
8
Q
- Microcontroller - silicon chip which includes
A
9
Q
microprocessor
A
memory & IO in a single
10
Q
package.

Q
What is a Microprocessor?
A
12
Q
• The word comes from the combination micro and
A
13
Q
processSor.
A
14
Q
Processor means a device that processes whatever. In
A
15
Q
this context processor means a device that processes
A
16
Q
numbers
A
specifically binary numbers
17
Q
• To process means to manipulate. It is a general term that
A
18
Q
describes all manipulation. Again in this content
A
it means to
19
Q
perform certain operations on the numbers that depend on the
A
20
Q
microprocessor’s design.
A
21
Q
What about micro?
A
22
Q
• Micro is a new addition.
A
23
Q
- In the late 1960’s
A
processors were built using discrete
24
Q
elements.
A
25
• These devices performed the required operation
but were too
26
large and too slow.
27
In the early 1970's the microchip was invented. All of
28
the components that made up the processor were now
29
placed on a single piece of silicon. The size became
30
several thousand tỉmes smaller and the speed becamne
31
several hundred times faster. The "Micro"Processor
32
was born.
