Application 08/246,179
flag selecting means for selecting an appropriate flag group in
accordance with an indication of data bit width in a conditional branch
instruction decoded by the instruction decoding unit; and
a branch judging unit for obtaining a branch condition from a decoded
conditional branch instruction and judging whether to branch, by
comparing the branch condition to the appropriate flag group.
The prior art references of record relied upon by the examiner in rejecting the
appealed claims are:

Queued Condition Codes", pp. 294-96.
Claims 1-12 stand rejected under 35 U.S.C. § 103 as being unpatentable over
Woods in view of Yamahata and IBM.

appellants, we make reference to the brief and answer for the details thereto.
