on a "greater than" condition, to other status conditions,
such as "carry," "overflow," and "zero." The status bit to be
used with the register pair conditional store instruction can
be designated by the instruction type and is not required to
be a mask bit in the instruction. The rejections of claims 10
and 22 over Auslander and Diefendorff and Kawata and
Diefendorff are sustained.
(10) Claims 41 and 43
Claims 41 and 43 depend on claims 10 and 22,
respectively, and recite at least two status bits from the
group of a negative status bit, a carry status bit, an
overflow status bit, and a zero status bit.
As discussed with respect to the rejection of claims 4-6
and 16-18, we agree with the examiner's finding that one of
ordinary skill in the art would have known that the claimed
negative status bit, carry status bit, overflow status bit,
and zero status bit are conventional status (or flag or
condition) bits.
One skilled in the art would have been motivated to provide
two or more of the claimed status bits for the results of ALU
operations in view of Auslander and common knowledge in the
