A processor is a chip or logical circuit that processes and responds to instructions to drive a computer. The main functions of a processor are fetching, decoding, executing, and writing back the operations of an instruction. Processors can be used in any system that incorporates computers, laptops, smartphones, embedded systems, and more. The two main components of a processor are the Arithmetic Logic Unit (ALU), and Control Unit (CU). The ALU performs the mathematical operations of the computer while the control unit operates like traffic control, managing the commands or operations of an instruction. The processor also communicates with other input/output devices and memory/storage devices. There are five types of general-purpose processors: microcontroller, microprocessor, embedded processor, digital signal processor (DSP), and media processor. This blog will analyze each type and its unique characteristics.
