*1:
In the case of word, it requires five steps for LD (s1
s2) and AND (s1
s2), and six steps for OR (s1
s2).
*2:
In the case of double word, for LD (s1
s2) and AND (s1
s2), it requires five steps when the combination of s1 and s2 is I/O
and I/O, six steps when the combination is either I/O and constant or constant and I/O, and seven steps when the combination
is constant and constant. For OR (s1
s2), one step is added respectively.
