floating-point accelerator definition hardware
(FPA) Additional hardware to perform functions on floating point
numbers such as addition, multiplication, logarithms
, 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.
