Application No. 08/160,573
plurality of data registers receives an input from the output
of the ALU and an input from the output of the shifter. At
pages 5-6 of the final rejection (Paper No. 7), the examiner
has provided a reasonable analysis as to why the presence of
registers, as broadly recited in claim 9, would have been
obvious to the artisan in view of the applied prior art.
Appellants contend that claim 9 requires both storage of the
shifter output in a data register and storage of the output of
the ALU in a data register. Appellants then point to instant
Figure 5 to illustrate a “connection” from barrel rotator 235
via Bmux 227 and multiplier destination bus 203 to data
registers 200. Appellants then argue that neither Ing-Simmons
nor Chu discloses the particular connection between the output
of the data registers and the plurality of data registers
recited in claim 9.
We agree with the examiner’s response, at pages 12-13 of
the answer, to appellants’ arguments. Clearly, Chu discloses a
shifting and an output of the ALU is fed to a register (see
Figure 1 of Chu). We agree with the examiner [answer-page 13]
that “shifting amount and direction is dependent upon the
