(Or "accelerator") Hardware, often an integrated circuit, which assists the main processor (the "CPU") by performing specific functions faster than the main processor could.

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

The coprocessor may decode instructions in parallel with the main processor and execute only those instructions intended for it.
