Multi-Precision Radix-4 SRT Division

  • David M. Russinoff
Chapter

Abstract

Unlike the dedicated double-precision multiplier and adder described in the preceding two chapters, a single module of our FPU performs floating-point division and square root extraction at all three precisions: double, single, and half. This module is modeled, however, by two separate functions, fdiv64 and fsqrt64, the first of which, displayed in Appendix D, is the subject of this chapter. This function is based on the implementation of the minimally redundant radix-4 case of SRT division that is addressed by Lemma  10.7 of Sect.  10.2.
