Coprocessors In A Personal ComputerThe word coprocessor encompasses many of the components in a PC, broadly speaking the PC has several coprocessors in a standard system. The keyboard and mouse controller device is a coprocessor that performs functions such as scanning the key presses and mouse movements. Coprocessors relieve the computer's microprocessor of specific processing tasks.
