What is a coprocessor used for?
A coprocessor is a computer processor used to supplement the functions of the primary processor (the CPU). Operations performed by the coprocessor may be floating-point arithmetic, graphics, signal processing, string processing, cryptography or I/O interfacing with peripheral devices.
What is the difference between a processor and a coprocessor?
The difference between processor & coprocessor includes the following. The processor is the main processing unit in the computer that executes different arithmetic, logic & control operations based on the instructions. The coprocessor is a special processor that gives support to the main processor.
Do math coprocessors still exist?
The math coprocessor was an optional add-on for the Intel 8086, 80386 and 80486 processors that allowed computers to perform faster mathematical calculations, increasing its overall performance. Today, all computer processors are released with a math coprocessor incorporated onto the processor.
Why do we need coprocessor?
By taking specialized processing tasks from core CPU, coprocessor reduces the strain on the main microprocessor, so that it can run at a greater speed. A coprocessor can perform special tasks like complex mathematical calculations or graphical display processing. They perform such jobs faster than core CPU.
