CPU is a condensation for Central Processing Unit. The CPU is an essential component of the personal computer that processes data and performs mathematical-computer calculations.
The CPU provides the programming capacity, and together with the memory and the input/output devices. It is one of the computational components that we find throughout the history of computers. The microprocessors of a chip have been replacing the CPUs until reaching the current days when usually when referring to this term, it is spoken of the microprocessors.
In the beginning, when we started talking about CPUs in the 1960s, this unit had a large size. Still, over the years, technological development led to computers today having higher reliability, technical security, and efficiency processing. It should also note that in the beginning, due to their price, size, and usability, the use of CPUs was only in universities.
Then they spread thanks to private business developments through a social process similar to Fordism. And which invested in the idea that all people should have access to acquire a personal computer, which allowed production to develop from then on. A dizzying way, by leaps and bounds.
About every 18 months, CPU efficiency and power doubles due to technological innovations. There are two typical components that a CPU needs: the arithmetic unit (logic) and the control unit, which only extracts the instruction from memory, decrypts it, and executes it.
The CPU is based on the operations of programs specially designed for computer transmission and use, whose necessary steps are to collect information, decode it into minor parts in which it can interpret this encoding, and carry out instructions, which it will ultimately execute, at which time in which different parts of the CPU have involved that act together. We find a fourth instance, which we can call writing, the use of which is to leave the results of the already completed task and established.
Processors do not interpret any information, but can only interpret information written in binary form. This computer language is based on two characters, zeros and ones.
Also, it always goes to the information provided by the clock signal, through which it is in sync. And connecting the different tasks and operations of the CPU.
The CPU architecture is the combination of the design and its instruction set. These instructions are called ISA, it is the programming model that a processor has. It also includes the assembly language form of a compiler.
The presentation of microarchitecture is as a diagram, which describes the architecture. That is the channel of the interconnections of the different elements of the machine.
