What Are Microprocessors and How Do They Work?


Within the realm of computing, microprocessors are an integral technology that has constantly pushed the limits of computer hardware and capability throughout their history. At their most basic, microprocessors are integrated circuits that encompass the central processing unit (CPU) and work to translate inputted binary data into outputted data. The amount of microprocessor assembly parts, such as transistors have gradually increased, allowing technological advancement from 4-bit to 64-bit technology over their history, greatly increasing the complex processes that the microprocessor can handle. Microprocessors can also serve a variety of applications, ranging from controlling elevators to operating complex computer systems.

 Microprocessors hold many advantages as compared to previous circuit board technologies. For example, with the use of integrated circuit parts, microprocessors are much cheaper than their previous counterparts. This translates into the reduction of price of the systems that utilize microprocessors. Alongside this, the memory and processor parts within integrated circuits allow for high speed capability while remaining at small sizes. Due to their small size and advanced technology, microprocessors boast less power consumption, heat generation, and failure rate as compared to other similar predecessors. Through the advent and development of microprocessor technology, systems like computers have been able to evolve from expensive, house sized structures to small affordable laptops and tablets.

There are many microprocessor assembly parts that come together to provide the capabilities that many systems now rely and benefit from. These parts include transistors, resistors, and diodes that all work together to provide functionality. Cache memory parts are integrated into the processor itself, allowing it to access data much quicker than even RAM sticks or solid state drives. A microprocessor’s operations in general is to fetch, decode, and execute information and instructions. To achieve these functions, a microprocessor receives an instruction and decodes it, then it executes an operation based on the decoded instruction. Depending on the application of the microprocessor and the system that contains it, the instruction set may vary.

The microprocessor that is credited with being the first produced came in 1970 when Garrett AiResearch was contracted by the US Navy to produce technology for the main flight control computers of the F-14 Tomcat aircraft. Publications of the microprocessor technology and design were not publicly released until 1998, to which at that time other microprocessors such as the Intel 4004 and 8008 had already been long released and in use. The Intel 4004, considered to be the first commercially available microprocessor, was released in 1971 and featured a 4-bit architecture. Since then, many microprocessors have been developed, constantly building and improving upon their predecessors with higher bit architecture, more transistors, and faster processing. Currently, technologies such as multi-core processors have continued this trend of growth, further pushing microprocessor technology to the limits.
