A coprocessor is an electronic circuit that is responsible performing specialized functions in conjunction with the main processor, providing basic operation.
A coprocessor is an additional processor unit or entirely different circuit designed to supplement a computer’s central processing unit (CPU).
Its core functionality is to offload other CPU-intensive tasks from the CPU to achieve accelerated system performance, allowing the CPU to focus on essential system tasks.
There are different types of coprocessors available to perform unique tasks – from interface I/O or encryption, to string processing, floating point arithmetic and signal processing.
