introduction to microprocessor

1. Introduction To
Microprocessor
&
Its Applications

2. Microprocessor
• It 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.
• A microprocessor is a programmable VLSI chip
which controls and performs all operations in a
microcomputer. Its main units are-
– ALU
– Registers
– Control Unit

3. • A microcomputer is a programmable machine.
Modern computers are electronic and digital. The
two principal characteristics of a computer are:
– It responds to a specific set of instructions in a well-
defined manner.
– It can execute a prerecorded list of instructions (a
program)
– Its main components are
• CPU
• Input & Output devices
• memory

6. History
• The development of the first microprocessor
began in 1969, when Intel engineer Marcian
Edward "Ted" Hoff proposed to use a single-chip,
general-purpose CPU to perform most computer
programming functions.
• The result was the first microprocessor, the 4004,
which was announced by Intel in 1971.
• This microprocessor evolved into a series of
increasingly powerful Intel chips--the 286, 386,
486, and in 1993, the Pentium--for the
International Business Machines (IBM) Corp.
personal computer (PC) and IBM-compatible
PCs.

• Meanwhile, Motorola Corp. developed the
68000 series of chips for the Macintosh
personal computer made by Apple Computer.
• Further advancements have led to robust
microprocessors, such as the Intel core i7
microprocessor that is capable of rendering 3D
images.
