Appeal No. 1999-0485
Application 08/526,781
operation means to n-bit length in accordance with a
rounding signal provided by said instruction means, said
rounding processing means not rounding the output of said
shifting operation means when the arithmetic instruction
is indicative of a logical operation and rounding the
output of said shifting operation means when the
arithmetic instruction is indicative of an arithmetic
operation.
We note that Appellant’s claim 13 recites
a rounding unit, coupled to said shifter, for rounding
the shift data when said arithmetic operator provides
resultant data based on an arithmetic operation and for
not rounding the shift data when said arithmetic operator
provides resultant data based on a logical operation.
Finally, we note that Appellant’s claim 25 recites method step
d) rounding the shift data when the resultant data is
provided based on an arithmetic operation and not
rounding the shift data when the resultant data is
provided based on a logical operation.
Thus, we find that all the independent claims require a
rounding process which selectively rounds based on an
arithmetic operation or selectively does not round based upon
a logical operation.
