When the central processor unit is made of only one integrated circuit, it becomes a microprocessor. It has millions of transistors and electronic components to process multiple instructions at a time. All this is on one silicon chip which has memory and other special features to support the computer system. <\/span><\/p>\n

It is programmable in a way to read binary instructions from memory and then execute the task to deliver the needed output. It is useful for storing data, device interaction, and sending\/receiving data simultaneously.\u00a0<\/span><\/p>\n

A Microprocessor has many components like transistors, registers, and diodes which come together to perform. The ability of the chip has become more complex with technology evolution. The functionality has become better and the speed has become faster. <\/span><\/p>\n

Now, most devices need to have a microprocessor to function. It is the element that brings intelligence to a device. Be it a computer or mobile phone, all devices need an interface to handle data that only a microprocessor provides. And it still has a long way to go with the development of artificial intelligence.\u00a0<\/span><\/p>\n

Working of a Microprocessor<\/h3>\n

There are three steps that a microprocessor follows –<\/p>\n

1. Fetch <\/b>– The instructions are in storage from where the processor fetches them.<\/span><\/p>\n

2. Decode <\/b>– It then decodes the instruction to assign the task further. During this, the arithmetic and logic unit also performs to register the data temporarily.\u00a0<\/span><\/p>\n

3. Execute <\/b>– The assigned tasks undergo execution and reach the output port in binary form.\u00a0<\/span><\/p>\n

Block Diagram of a Microprocessor<\/h3>\n

Arithmetic and Logical Unit, Control Unit, and Register array make up the microprocessor. The ALU deals with input devices or memory for receiving data. The control unit takes care of instructions and structure. Register array identifies and saves the registers like B, C, and accumulator.<\/p>\n
