FINDINGS OF FACT
The following Findings of Fact (FF) are shown by a preponderance of
the evidence.
Huang
1. The prior art Huang patent describes that “[i]f the generation of
the result produces one of a predetermined set of special operands, a tag
generator also generates a tag having a predetermined tag value
corresponding to the produced special operand.” (Col. 5, ll. 43-46).
2. The prior art Huang patent describes that “each of the registers
116 and 118 has an operand value storage portion 116-1 and 118-1 and a tag
value storage portion 116-2 and 118-2.” (Col. 6, l. 66 through col. 7, l. 2).
3. Figures 1-3 of Huang show a conventional arithmetic
calculation circuit where one or more operands x and y are supplied from a
memory device, such as a register file 12 and the operands x and y are
inputted to an arithmetic section 14. (Col. 1, ll. 40-42).
