9 The residual is in redundant form, represented by the pseudosum
WS
and
stored-carry
WC
bit-vectors. For simplicity, we use w[j] in the description.
9 m is the precision in bits.
9 SEL
is the continued-product digit selection function defined by
/ A
1 if w[j]>0
s j =SEL(w[j])
= 0 if-l_<w[j]_<0.25
-1 ifw[j]<-0.75
where w [j ] is an estimate of the residual w [j ] with t = 2 fractional bits.
