The processor is the CPU of your computer. While, the coprocessor provides supplementary functions to the computer. These functions are generally not possessed by the main processor like hardware encryption. But, we cannot use a coprocessor alone, and it is always dependent on its main processor for its functioning. A coprocessor makes a processor more powerful and efficient.

Some examples of pairs are: 80386 – 80387 intel microprocessors.

Normally, when you say “processor”, it is generally understood to mean the CPU. The processor is the logic circuitry that processes and responds to basic instructions that make a computer work. It has four basic functions namely fetch, decode, execute, and write-back. Among the basic elements of a processor include the ALU or the Arithmetic Logic Unit.

This component or element performs the mathematical and logic operations on operands in instructions. Another element or component is the FPU or the Floating Point Unit. This element is also known as the math coprocessor or the numeric coprocessor. It is a specialized or dedicated coprocessor that manipulates numbers much quicker than the normal microprocessor circuitry.

Another element is the register which is designed to hold instructions and other data. Registers provide operands to the arithmetic logic unit and store the results of operations. A coprocessor, on the other hand, is a special set of circuits in a microprocessor chip designed to manipulate numbers or do some other specialized function much quicker than the basic microprocessor circuits.

It offloads specialized processing operations which then decreases the load on the basic microprocessor circuitry allowing it to operate at best possible speed.
