hey guys hope you're all doing it and welcome back to a channel I'm gonna start this video with a weird statement imagine you have to function without a brain well that sounds downright impossible right even while these words are being said they're being registered into your brain for understanding and processing just like how the brain serves as the functioning mechanism in your body a microprocessor serves as the functioning mechanism of a computer in other words these micro processors are the grain of your computer your mobile phone and most other electronic devices that you may use in your day-to-day life in this video you will come across a brief introduction to micro processors now let me ask you a simple question do you think that our fans and to blights have a microprocessor in them if your answer is no well you guessed it right why do you think that well this is because they don't require any processing in them you basically switch it on and your fan starts rotating at the speed at which it is set similarly a tube light starts emitting light when it is switched on then what are the other areas in which micro processors are used micro processors are used in any equipment that requires some sort of processing to be done from the traffic light two remotes to a computers all have micro processors in them these processors have an algorithm and they work in a previously programmed manner according to the instructions given now you must be wondering where and how did the invention of micro processors take place well micro processors were first invented 50 years ago at a young Silicon Valley startup called Intel the first microprocessor was the Intel for double of four invented in 1971 and it was a 4-bit processor it was soon succeeded by Intel aw8 in 1972 and since then the development in micro processors has been huge back in 2018 Intel released its AI 9 double 9 double zero K which is a ninth gen processor and was claimed to be the fastest gaming processor in the world by Intel at that time now coming to the components of the micro processor they are divided into three basic segments the ALU registers and a control unit each of these has a specific predefined role first component that is the ALU or arithmetic logic units are the building blocks they perform all mathematical and logical calculation on the data that has been fed into it mathematical calculations include addition subtraction multiplication etcetera and the logical calculations are the and or and not operations next we have the registers the registers are temporary data storage locations in the microprocessor depending upon the need they either hold data or point in the direction where the data is located registers are divided into three categories namely general-purpose registers specific registers and memory registers depending on the need data can be stored or extracted from them accordingly the control unit controls the operation in the microprocessor it dictates how the internal memory of the computer should respond to the given instructions and controls the flow of data between the microprocessor and the system microprocessor is further connected to the input devices memory unit and the output devices the input devices are used to feed information into the micro processors the memory unit is the internal storage unit of the microprocessor it is commonly known as the RAM this unit stores all data and information that is required for processing it also stores intermediate results of programming finally we have the output devices the output devices provide the results of the data that has been computed by the processor the output can be in multiple forms it can be in visual form when you consider the monitor of your computer or it can be in an audible form when you consider the speaker of your computer next let us discuss how the microprocessor works the working of a microprocessor follows a simple fetch decode and execute cycle in this the microprocessor first fetches the function to be executed from the memory now the instruction is present in an encoded form in the memory after it's been decoded the control unit of the processor then passes these decoded instructions to be executed this cycle continues till a stop instruction is reached or till the program ends well that's it for this video guys in this video we learned about how micro processors are an indispensable part of any computational device how they came into existence and how they function in our upcoming videos we learn more micro processors until the next one bye you
