What Is a Microprocessor Chip?

A microprocessor chip is a processing unit which integrates all the capabilities of a CPU into one circuit. Moving all the components of a CPU into one circuit allows for many advantageous in efficiency and up-scalability. It is this "all in one chip" design that has allowed for streamlined CPU improvements over the years in computing.

History

1. Some of the first microprocessors were used in the 1970s within calculators to perform simple mathematical calculations. As research progressed and cost of production diminished these microprocessors evolved into the CPU within every modern computing solution.

Function

2. Originally designed for specific electronics applications these microprocessors performed specialized data operations using binary instructions. With the advent of the general purpose processor however, microprocessors have grown to be able to encompass a vast array of possible applications using only one microprocessor design that supports many general purpose operations.

Benefits

3. Modern microprocessors have advanced to such a state that they aid in virtually every endeavor by mankind from missile defense systems to simple calculators. Their continued advancement and implementation have aided in countless discoveries and improvements to our way of life.

Time Frame

4. Although research was initially taking place as early as the 1920s it was not until the early 1970s that major advancements in the microprocessor's design and abilities allowed for widespread acceptance and application. Today the microprocessor market is measured in billions of dollars every year with no signs of discontinuation in sight.

Potential

5. Although the limits of physics currently limits our traditional methods used to advance microprocessor power there are new techniques such as multi-core designs and new materials such as Hafnium being used to explore ever greater advances in this seemingly unlimited technology.
