floating-point accelerator
     
        (FPA) Additional hardware to perform functions on
        floating-point numbers such as addition, multiplication,
        logarithms, exponentials, trigonometric functions and various
        kinds of rounding and error detection.  A floating-point
        accelerator often functions as a {co-processor} to the {CPU}.
     
        The term "floating-point accelerator" suggests a physically
        larger system, often an extra circuit board, whereas a
        "floating-point unit" is probably a single chip or even part
        of a chip.
