Double-Precision Addition and FMA

  • David M. Russinoff
Chapter

Abstract

The double-precision addition module fadd64 supports both the binary FADD instruction and, in concert with the multiplier, the ternary FMA instruction. Thus, both operands may be simple DP encodings, or one of them may be an unrounded product in the format of the data output of fmul64 as described in Chap.  16.
