Conditional jumps are harder for pipelined execution than normal data dependencies, because they can change which instruction should be next in the stream of instructions flowing through the pipeline. This is called a control dependency, as opposed to a data dependency (like an add where both inputs are outputs of other recent instructions). The long conditional jump becomes two instructions: a NOP and a JMP. NOP is a specific instruction used for padding, it does nothing and cost only one bytes in memory and one CPU cycle. Opcode of a NOP is 90. As example, if I want to force this conditional …

The various types of control transfer instruction in Assembly Language include conditional and unconditional branches and call instructions. Looping in PIC assembly language will be performed using an instruction to decrement a counter and to jump to the top of the loop if the counter is not zero. The will be accomplished with the BNZ In the x86 assembly language, the JMP instruction performs an unconditional jump. Such an instruction transfers the flow of execution by changing the instruction pointer register. There are a number of different opcodes that perform a jump; depending on whether the processor
