A special-purpose processing unit that assists the CPU in performing certain types of operations. For example, a math coprocessor performs mathematical computations, particularly floating-point operations. Math coprocessors are also called numeric and floating-point coprocessors.
Most computers come with a floating-point coprocessors built in. Note, however, that the program itself must be written to take advantage of the coprocessor. If the program contains no coprocessor instructions, the coprocessor will never be utilized.
In addition to math coprocessors, there are also graphics coprocessors for manipulating graphic images. These are often called accelerator boards.
(v) (1) To copy a piece of data to a temporary location. In word processing, for example, copying refers to duplicating a section of a document and placing it in a buffer (sometimes called a clipboard).

- core clock
The actual speed at which the graphics processor on a video card operates. Core clock is measured in megahertz (MHz). The core clock speed can sometimes be changed on newer cards where users want to gain a performance boost. This is called overclocking and it can usually be done using third-party utilities or the drivers […]
- core logic
Also referred to as the core logic chipset, the central processing logic of a complete system (such as a desktop PC), a component of that system or a function of a specific component. A system��s core logic can include a controller for handling memory functions, a cache for instructions, the logic for bus interfaces and […]
