ADD and INC Tags: CPUs Last response: April 9, 2011 10:13 PM in CPUs Share rand7391 April 9, 2011 8:37:46 PM hi I want to know what the effect that ADD AL,1 and INC AL make on flag register thank you More about : add | E-mail me updates | Report abuse Register or log in to remove popatim CPUs Master April 9, 2011 10:13:25 PM Add AL,1 will add 1 to the AL register and store the result in the AL register. I think you can figure out what INC AL does on your own. If a calculation gives a zero answer, set the Z zero flag. If a calculation gives a negative answer, set the S sign flag. If a calculation overflows, set the O overflow flag. An overflow happens if the result of a calculation has more bits than will fit into the available register. With 8 bit registers, the largest numbers that fit are -128 to + 127. | Report abuse Ask the community Publish Tom's Hardware>Forum>CPUs>ADD and INC> Related ressources: ForumIs this a good build £1500 budget inc VAT and Delivery ForumNew Build - CyberPower Inc - $2500 or less Forumproblem installing xp inc sp2 Forum[FS] Three BenQ G2222HDL's inc .
