A personal computer processor or central processing unit is a microcircuit designed to execute program code. The CPU is the heart of a computer's hardware.
The architecture of the central processor is constantly changing, but the tasks performed by this device remain constant. Modern CPUs have the following characteristics: power consumption, clock speed, architecture, and performance. Initially, each central processing unit was created for a unique computer system. Naturally, this method was expensive and ineffective.
Manufacturers began to produce serial models of central processing units, divided into classes and types. This made it possible to quickly replace a damaged CPU and apply a single processor model when creating various devices. The creation of a miniature central processing unit made it possible to significantly reduce the size of a personal computer and similar devices.
It should be noted that processors are used in many modern electronic devices such as cell phones and cameras. They are usually presented in the form of microcontrollers. Their power is much lower than that of a computer's CPU, but it is quite enough for certain tasks. The performance indicators of modern microcontrollers exceed the power of the central processor of a computer a decade ago.
Most modern CPU computers operate according to the principle of data processing sequence. It was developed by John von Neumann. Currently, this algorithm has been modified, but its essence remains the same. Currently, multi-core processors are being actively produced. They represent a single package containing processor cores. This architecture allows the simultaneous execution of instructions independent of each other, which significantly improves the performance of the CPU as a whole.
Multi-core processors can be a set of individual crystals, the number of which is equal to the number of cores. Sometimes a scheme is used that combines 2 cores in one crystal. This reduces the cost of manufacturing the CPU while reducing its performance.
