8: BOOLEAN COMPUTATION INSTRUCTIONS
Introduction
Boolean computations use the AND, OR, and exclusive OR statements as carried out by the ANDW, ORW, and XORW instructions in
the word or double-word data, respectively.
ANDW (AND Word)
ORW (OR Word)
XORW (Exclusive OR Word)
S1
·
S2 → D1
When input is on, 16- or 32-bit data assigned by source devices S1 and S2
are ANDed, bit by bit. The result is set to destination device D1.
S1 = 1 1 1001
S2 =
