The CPU provides the programming capacity. Together with the memory and the input/output devices, it is one of the computational components that we find throughout the history of computers.
Microprocessors on a chip have been replacing CPUs until the present days when usually when referring to this term, microprocessors are spoken of.
When we started talking about CPUs in the 1960s, this unit had a large size. Over the years, technological development has led to computers today having a process with greater reliability, technical security, and efficiency. It should also be noted that in the beginning, CPUs were only used in universities due to their price, size, and usability.
Then they spread thanks to private business developments through a social process similar to Fordism, which invested in the idea that all people should have access to acquire a personal computer, which allowed production to develop from that point 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 or called logic, and the control unit, which only extracts the instruction from memory, decrypts it, and executes it.
The CPU is based on operations of programs specially designed for computer transmission and use, the basic steps of which are to collect information, decode it into minor parts in which it can interpret that encoding, and carry out instructions, which it will ultimately execute.
At this time, in which different parts of the CPU have involved that act together. We find a fourth instance, which we can call writing, which is used to leave the results of the already completed task completed and established.
The processors do not interpret any information, but can only interpret written information in binary form. This computer language is based on two characters, zeros and ones. Besides, 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, for its acronym in English, it is the programming model that a processor has, it also includes the assembly language form of a compiler.
The microarchitecture is presented as a diagram, which describes the architecture, that is, the channels of the interconnections of the different elements of the machine.
