(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. (1994-12-01)
