How do conditional jumps work?
Conditional Jumps: Branching in Assembly
A conditional jump instruction, like "je" (jump-if-equal), does a goto somewhere if the two values satisfy the right condition. For example, if the values are equal, subtracting them results in zero, so "je" is the same as "jz".What is the function of the conditional jump in writing and assembly language program?
The conditional jumps use as a condition the flags or logical combination of the flags. The flags can be set by any of the instructions that affect the flags.How does CPU implement conditional jump?
? To implement a conditional jump, the CPU looks at the Flag registers. ? If the conditions for the jump (expressed as a combination of status flag settings) are true; the CPU adjusts the IP to point to the destination label, so that the instruction at this label will be done next.- a.
- Conditional jump evaluates the state of specified flag to determine whether to fetch its next instruction from the jump destination location or to fetch its next instruction from the next sequential memory location.
