Introduction to The Microprocessor
and PC
Chapter 1:
1. What mankind has done before the
microprocessor finally came out?
2. How many parts are there in the
microprocessor ?

Introduction to The
Microprocessor and PC
• 1.1 A Historical Background
• 1.2 PC Based on Microprocessor
1.1 A Historical Background
1.1 A Historical Background
• A. The Mechanical Age
– Abacus (Babylonians)
– Analytical engine (Babbage, punched cards,
1823,failure)
1.1 A Historical Background
• B. The Electrical Age
– Motor-driven adding machines, based on
mechanical calculator (Hollerith, set up IBMInternational Business Machines Corporation)
– First electronic calculating machine Z3 (German,
Konrad Zuse,1942)
– The first general-purpose, programmable
electronic computer ENIAC (University of
Pennsylvania, 1946)

The Moore’s Law:
the number of
transistors integrated in a chip will double very
18 or 24 mouths
1.1 A Historical Background
• D. The Future of Microprocessors
– The process speed will get more
faster
– The memory will get more large
– The bulk will get more smaller
– The width of data bus will increase
– Architecture will get more efficient
1.2 PC Based on Microprocessor
1.2 PC Based on Microprocessor
• Question: If we use a computer to
figure out an arithmetic expression,
how can it finish this work?
• 133*33+44*14
1.2 PC Based on Microprocessor
• 133*33+44*14
– First input these numbers.
– Do the calculating work.
– Store The result
– Output the result.
• Control this processing.

1.2 PC Based on Microprocessor
• Bus: P25
– Address bus requests a memory location
from the memory or an I/O location from
the I/O devices.
– Data bus transfers information between
the microprocessor and its memory and
I/O address space.
– Control bus contains lines that select the
memory or I/O and cause them to perform
a read or write operation.
