Working of Microprocessor

The microprocessor follows a sequence to execute the instruction: Fetch, Decode, and then Execute.
Initially, the instructions are stored in the storage memory of the computer in sequential order. The microprocessor fetches those instructions from the stored area (memory), then decodes it and executes those instructions till STOP instruction is met. Then, it sends the result in binary form to the output port. Between these processes, the register stores the temporary data and ALU (Arithmetic and Logic Unit) performs the computing functions.

Features of Microprocessor

• Low Cost - Due to integrated circuit technology microprocessors are available at very low cost. It will reduce the cost of a computer system.
• High Speed - Due to the technology involved in it, the microprocessor can work at very high speed. It can execute millions of instructions per second.
• Small Size - A microprocessor is fabricated in a very less footprint due to very large scale and ultra large scale integration technology. Because of this, the size of the computer system is reduced.
• Versatile - The same chip can be used for several applications, therefore, microprocessors are versatile.
• Low Power Consumption - Microprocessors are using metal oxide semiconductor technology, which consumes less power.
• Less Heat Generation - Microprocessors uses semiconductor technology which will not emit much heat as compared to vacuum tube devices.
• Reliable - Since microprocessors use semiconductor technology, therefore, the failure rate is very less. Hence it is very reliable.
• Portable - Due to the small size and low power consumption microprocessors are portable.
