What is Superscalar processor?

Supercalar Processor is a type of processor that can perform multiple sets of instructions at the same time. This type of processor contains several sub -units that control certain types of basic functions. While other processors also have these units, the Superscalar processor may have information sent directly to these units for processing, while the main processor is busy with something else. The Superscalar processor is the center of three main types of processors. Every time something happens on the machine, the CPU works a little before it really happens. As a result, the processor is very busy and the time spent with it very valuable. When the CPU reaches its limit, other computer functions remain and wait for the processor to catch up. The main processor majority of calculations for the computer system. Other systems such as an arithmetic logic unit have very specific functions and are used less than the main processor. In the case of an arithmetic logic unit, it performs low -level mathematical functions for a computer.

At this point, computer processors are divided into three wide categories: scalar, superscalar and vector. A scalar system is a type of processor that most users are known to. This processor receives one command at once and performs them in the order or order of priority. These processors make up most of domestic and business computers.

vector processors receive multiple commands at the same time via field system. A series of commands arrive at the same time at the main processor core. These commands are considered to be the processor as individual parts of the larger command and performed simultaneously.

Supercalar Processor is the center between these two methods. The main processor is able to take only one command at a time, similar to a scalar processor. On the other hand, there are direct connections to the secondary processor systems, which is not commonly present in other forms of the processor. These connections allow the information to be directly fed into subsystems,Where they can perform specific commands and output information separate from the main processor. This allows the processor to work and issue multiple instructions such as a vector processor.

This operation must not be confused with a multi -core processor. In fact, these systems have more than one whole processor active at once. To become a superscalar processor, commands go to sub -units, not on the whole systems. In most cases, the multi -core system is a collection of scalar, processors, but it is possible to also be superscalar processors.
