226 Chapter 6 Implementation of floating-point arithmetic on a computer
At the end of Section 6.5 where multiplication w as considered, we mentioned that
every digital processor should also be able to deliver the double length unrounded
product. Such double length products cannot be efficiently produced by the short ac-
cumulator. This consideration gives very high priority to the choice of at least the long
accumulator for floating-point operations.
Nevertheless, our study of the short accumulator is useful. In numerical analysis,
computation of the sum of two products a b C c d of floating-point numbers is a
frequent task which is often very crit ...
