where
dam = 2 * (res + i * (1 + den)) clock cycles
res= number of de/unnormalized results.
den= number of source operands with U-tag or V-tag set.
i = 0, if den=0; 1 otherwise.
dams= 2 * (res + i * (1 + den)) clock cycles
res= number of multiplier and add/sub 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.
damx= 2 * (res + i * (1 + den)) clock cycles
