Appeal No. 1999-0485
Application 08/526,781
Appellant’s claim 25 is directed to a method of performing a
combined processing operation on a received data packet which
includes digital data and instruction data and includes in
combination steps a) through d). Appellant points out that
step d) as claimed includes 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. Appellant argues that
Toriumi does not disclose these limitations as recited in
Appellant’s claim 25.
We note that Appellant’s claim 1 recites
rounding processing means, coupled to receive an output
value of said shifting operation means, for rounding the
output value of said shifting operation means to n-bit
length in accordance with a rounding instruction provided
by said instruction decoding means, said rounding
processing means not rounding the output value of said
shifting operation means when the arithmetic instruction
is
indicative of a logical operation and rounding the output
value of said shifting operation means when the
arithmetic instruction is indicative of an arithmetic
operation.
We further note that Appellant’s claim 6 recites
rounding processing means, coupled to said shifting
operation means, for rounding an output of said shifting
