Assembly Zero Flag at Vernon Palacios blog

Assembly Zero Flag. Conditional branching allows instructions such as jump if zero or carry condition to alter the order of operations by testing flags. The zero flag indicates that an operation produced zero. If there is a carry out from the most significant bit (msb) on addition, or there is a borrow into the msb on subtraction, cf will be 1. For zero result, it will be 1. The zero flag is quite simple if the result of the operation is a zero the zero flag will be set otherwise it will be clear. Its purpose is to indicate whether the result of a previous arithmetic or. For example, if an operand is subtracted from another of equal. Status flags (cont’d) • uses of zero flag. For zero result, it will be 1. A carry flag (cf) indicates that an arithmetic operation resulted in zero, whereas a zero flag (zf) indicates that two numbers were added and the result was overflow. The zero flag (zf) is a conditional flag in assembly language that is part of the status flags or flags register. ∗two main uses of zero flag. Zf = 1 if char is $ cmp ax,bx » counting to a preset. If there is a carry out from the most significant bit (msb) on addition, or there is a borrow.
