Algorithms for Floating-Point Arithmetic on Integer Processors

In [37] we present floating-point division algorithms and implementations. We compare all standard algorithms and propose a high-radix digit-recurrence algorithm which gives a speed-up factor of about 3.

Division by Constant

The work done in 2001–2003 by J.-M. Muller, A. Tisserand, B. Dupont de Dinechin (STMicroelectronics) and C. Monat (STMicroelectronics) on the division by constant for the ST100 DSP processor has been presented in ARITH17  [44] .
