(computer science)
A processing unit that works together with a primary central processing unit to speed a computer's execution of time-consuming operations.

coprocessor

Any computer processor which assists the main processor (the "CPU") by performing certain special functions, usually much faster than the main processor could perform them in software. The coprocessor often decodes instructions in parallel with the main processor and executes only those instructions intended for it.

The most common example is a floating point coprocessor (or "FPU"), others are graphics and networking.

coprocessor

A secondary processor in a computer that is used to speed up operations by taking some of the workload that the main CPU would otherwise have to handle. See GPU, GPGPU and math coprocessor.
