Appeal No. 96-1621
Application No. 08/194,899
double word is to be executed simultaneously with
the instruction in the odd word of the current
double word. When non-aligned instructions are
bundled, this means that the instruction in the even
word of the current double word is to be executed
simultaneously with the instruction in the odd word
of the previous double word.
It appears that Blaner describes exactly this at column
5, lines 35-44. Two instructions at a time are processed in
parallel:
A tag bit value of “one” means that the instruction
is a “first” instruction. A tag bit value of “zero”
means that the instruction is “second” instruction
and may be executed in parallel with the proceeding
[sic, preceding] first instruction. An instruction
having a tag bit value of one may be executed either
by itself or at the same time and in parallel with
the next instruction, depending on the tag bit value
for such next instruction.
Thus, a tag bit value of “zero” might be considered an
indication of non-alignment, causing the instruction to be
bundled with the preceding instruction while a tag value of
“one” might be considered an indication of alignment, wherein
the instruction is to be bundled with the next instruction.
Accordingly, we will sustain the rejection of claims 36
and 37 under 35 U.S.C. 103.
