Appeal No. 2002-1672
Application No. 09/412,124
Accordingly, Nakano discloses the claimed invention except
that Nakano lacks an explicit disclosure of storing acquired
instructions in tracer memory, referring instead to the storing
of addresses, while also lacking an explicit disclosure of
providing the acquired instructions externally from the
processor. Bridges, however, provides a clear disclosure in
Figure 1, along with the accompanying description beginning at
column 4, line 1, of a tracing technique in which acquired
instructions related to a triggering event (Bridges, column 6,
lines 34-38) are stored and outputted externally over pins 118
and 119. It is submitted that the skilled artisan would have
recognized and appreciated the obviousness of utilizing acquired
instruction data for tracing purposes as taught by Bridges
instead of the acquired address data feature of Nakano, since the
use of address data rather than instruction data is merely a
shorthand technique for tracing program execution history. It is
further submitted that, although Nakano has no explicit
disclosure of the external output of acquired tracing
information, the skilled artisan would also have recognized and
appreciated the obviousness of such a feature as taught by
Bridges since the precise disclosed purpose of the tracing tool
of Nakano (column 1, line 47) is to enable a user to identify the
