Appeal No. 1997-1351
Application 08/127,924
and display tasks performed by RISC-based communications
processor 202 are "not time critical." The terms "time
critical" and "not time critical" are very broad. The fact
that Petty does not use these terms does not negate
anticipation of these limitations. Telephone conversations
over an ISDN interface are certainly time critical because
they happen in real time. The fact that data may be
re-transmitted if data is lost does not imply that data
should not be handled in a time critical manner.
Appellants also argue (Br10) that the Examiner erred in
finding that peripheral units 20-22 of Petty are connected
to both buses 208 and 23 because figure 2 of Petty shows the
peripheral units connected to RISC-based processor bus 208
and through the RISC-based communications processor 202 and
DMA 207 to the M68000 bus 23. The Examiner disagrees
(EA14): "As one can see in figure 2 which shows example
item 22, bus 23 is connected in more than one ways [sic] to
display 22. One connection is through SMC Channel through
the multiplexer and line 215. Another connection is through
SCP Channel through the multiplexer and the NOR gate.
Therefore, M68000 bus 23 is connected to display 22."
