Microprocessor is programmable single chip logic device that use to
control any device or start or stop any device.
As we have describe the earlier about the WHAT
IS THE MICROPROCESSOR ?
Revolution of Microprocessor being started with a bold and innovative
approach after invention of Integrated Circuited. The First Microprocessor of
the world was invented in 1971 name 4004 by Intel.
It is very interesting story, how the first microprocessor was designed.
In 1969 Intel Corporation’s engineer “Ted Hoff” were working on designing a
semiconductor memory. In 1969, Intel get a job to design a programmable
calculator from a Japanese Company Bucsicom. But when the calculator is
designed it original design have 12 different chip connected to each other to
form that programmable calculator. So it have became big size then requirement.
At that time Ted Hoff who was working in Intel (he was introduced 64-bit
Semiconductor bipolar RAM chip) suggest about a general purpose single chip that
can perform all the operations of that calculator and various logic functions,
on the basics of 0s and 1s binary numbers
provided to that single chip which is keep stored in registers, at the
appropriate timing. Group of Register is use to store any number in binary
number form.
And thus way Intel successfully designed that programmable calculator
withe help of single general purpose chip, and some time latter Intel got a
idea is that this general purpose single chip have a quality of processing data
store in group of registers and performing the various logical operations. And
keep this idea in the mind Intel became successful to designed 4-bit
microprocessor 4004 in 1971.
Question- What do you mean by 4-bit
microprocessor ?

And thus a way the improvement in the first designed microprocessor 4004
is started and Intel designed many advance versions of the processor likes……

It was not that only one company name Intel only designed the
microprocessor. Motorola was the second company which also designed many microprocessors
like…
Motorola 6800
Zilog Z80
