WebThis is performed by the JMP instruction. Conditional execution often involves a transfer of control to the address of an instruction that does not follow the currently executing instruction. Transfer of control may be forward, to execute a new set of instructions or backward, to re-execute the same steps. 2. WebMar 25, 2024 · There are more than 30 different conditional jump instructions, but following are some commonly used ones: JZ — Jump if Zero; checks for ZF = 1. JE — Jump if Equal; checks for ZF = 1. JNZ — Jump if Not Zero; checks for ZF = 0. JNE — Jump if Not Equal; checks for ZF = 0. JC — Jump if Carry; checks for CF = 1.
