arithmetic circuit with a ROM table. However, Yamaguchi
appears to solve the problem in a manner somewhat
differently than does the instant claimed invention.
Yamaguchi is apparently interested in looking up the
reciprocal of the square of the upper-bit data AH of a
divisor A rather than looking up the actual estimated
reciprocal term in a first lookup table, as claimed. Also,
Yamaguchi does not appear to employ a second lookup table
for looking up an error term, as is also claimed.
The examiner relies on Figure 14 and columns 9-11 of
Yamaguchi for the teaching of the elements of the instant
independent claims, identifying, at page 4 of the answer,
various lines in these columns. However, the examiner does
not particularly point out exactly what portions of the
Yamaguchi disclosure are alleged to correspond to the
instant claimed elements.
Apparently, the examiner is alleging that Yamaguchi’s
ROM 51 corresponds to the claimed second lookup table and
that ROM 52 would correspond to the claimed first lookup
table. But, if this is the case, the examiner’s
allegations are not borne out by the disclosure of
