Microprocessor
A microprocessor (sometimes denoted as µP), is a programmable digital electronic component; that is, it is a chip with multiple terminals that receives orders and executes them according to a program previously stored in an external memory chip. Thus, the microprocessor uses many functions, such as controlling an industrial process or variable according to the inputs from electronic sensors or user settings, and the microprocessor is placed in an integrated circuit chip that contains a huge number of microparticles, for example the Pentium 4 processor contains 15 million fryers . The CPU in most microcomputer systems consists of one or more chipsets of the microprocessor. The microprocessor consists of two basic modules, namely the unit of arithmetic and logic (ALU) and the console (CPU) and each of these units are internally composed of several components. The microprocessor differs from the microcontroller in that the latter contains, in addition to its main unit, the central processing unit into secondary units, which is a set of interfaces with the processor represented by internal memory, divided into read-only memory, read and write memory, and input and output ports , And may also contain digital analog converter, digital analog converter, timer, and digital filters.
