In the twentieth century, microprocessors had become one of the most and most significant accomplishments. Each year, the microprocessor moves closer to the center of the people’s life, staking out its place in the heart of one machine after another. It has become more difficult to dismiss the microprocessor as just another product in technology innovations.
None of the inventions has overgrown throughout the world or deeply touched so many aspects of human existence in history. Before the microprocessor becomes too invisibly embedded into the daily reality of a person’s life, it’s a time to celebrate the microprocessor and the revolution it has created. A person should appreciate what a miracle each of the tiny silicon chips really is and to meditate on what it means to the life of the people.
The microprocessor is a computer processor that incorporates the functions of a central processing unit on a single integrated circuit. Andrew Grove, Gordan Moore, and Robert Noyce were the people who had created the first microprocessor, which is known as the Intel 4004. In the first generation, in the year 1971, microprocessors were introduced as first-generation systems. Intel had created the 4004 microprocessor.
It has a 108KHz clock speed. It was a 4 – bit processor. Its primary function is to perform the basic arithmetic calculations in the second generation. In the year of 1973, second-generation microprocessors were introduced by Intel. They are mainly 8- bit processors such as Intel – 8085. It is mainly based on NMOS technology.
It is one of the microprocessors which has a super-fast speed—the third generation. In the third generation, 16- bit processors were invented by using the HMOs technology. It is used to contain 29,000 transistors. Initially, it was used to run at a speed of up to 5 MHz. In the 3rd generation, microprocessors used to work like mini-computer.
In the fourth generation, it was mainly witnessed with the development of the 32 – bit microprocessors by using the HMOS fabrication. They primarily used the VLSI technology. It used to contain about 5000 transistors mainly and also along with the other circuits—the fifth-generation. In the fifth generation, the microprocessor had many advancements, like it has high performance.
It also has a high speed that uses 64-bit microprocessors—some of the few examples like Celeron, Pentium, dual and quad-core processors. The old processor boards were 18 inches square and used the discrete logic and iron doughnut magnetic Ram on equal boards ten and more inches away. Other than that, chipsets used to assist the microprocessor and have now become infinitely easier to design. The physical design of computers becomes easier as PARMS of discrete logic got piled into programmable arrays.
