res = number of multiplier de/unnormalized results.
den = number of multiplier source operands with U-tag or V-tag set +
number of add/sub source operands with U-tag set.
i = 0, if den=0; 1 otherwise.
das = 2 * (res + i * (1 + den)) clock cycles
res = number of de/unnormalized results.
den = number of de/unnormalized source operands (U-tag set).
i = 0, if den=0; 1 otherwise.
dax = 2 * i * (1 + den) clock cycles
den = number of de/unnormalized source operands (U-tag set).
i = 0, if den=0; 1 otherwise.
daff If the accompanying Data ALU operation is a Data ALU NOP (MOVE or MOVETA)
then the "+da" term will be zero. Otherwise the "+da" term will be determined by the
Data ALU operation. If the specified condition is true, the "+da" term is as specified in
Figure A-8 for the Data ALU operation. If the specified condition is false, the "+da"
term is calculated as in the figure but always setting res=0.
