The three functions of a microprocessor are controlling the operations of a computer’s central processing unit, transferring data from one location to another and doing mathematical calculations using logarithms. A microprocessor is thought to function like a human brain and is essential in the operation of computers and digital devices.
The microprocessor receives instructions from all mother components of the computer, executes the desired functions and gives back timely yet efficient results. Microprocessors were first invented in 1971. Although they were not able to compute large instructions, nor support complex software, they were smart inventions of that time. Through the years, technology and innovation has enabled the production of more efficient and better organized microprocessors. Today, computers and other devices including the smart phone,
iPad, iPhone and tablet use high-end microprocessors. These devices basically have a set of instructions set digitally and a speed that gauges the number of instructions done. It uses using digital logic to jump from one instruction to another at super speed. The microprocessor operates on the platforms of two computer memories- read only memory (ROM) and random access memory (RAM).
Modern microprocessors are able to support audio, video, data and other software. Arguably, economic development can be credited to the modernization of the microprocessor.
