What is a Math Coprocessor?

A math co-processor is a processor different from the main microprocessor that performs additional functions or assists the main microprocessor in its work. The most common coprocessor is a floating-point coprocessor, also known as a digital or arithmetic coprocessor. It performs digital operations much faster and better than general-purpose microprocessors in microcomputers.

Specific processing tasks

Coprocessors can also expand the instruction set by providing a new set of specialized instructions. For example, a dedicated set of instructions can be added to the standard ARM instruction set to handle vector floating-point (VFP) operations.
