A NOP is most commonly used for timing purposes, to force memory alignment, to prevent hazards, to occupy a branch delay slot, to render void an existing instruction such as a jump, as a target of an execute instruction, or as a place-holder to be replaced by active instructions later on in program development (or to …
How does loop work in assembly?
- The loop instruction always extracts the number of iterations from the ECX register.
- The loop instruction decrements the value of ECX and compares it with zero.
- If the value in ECX is equal to zero, the program jumps to the L1 label; otherwise, the program exits the loop.

The LOOP instruction assumes that the ECX register contains the loop count. When the loop instruction is executed, the ECX register is decremented and the control jumps to the target label, until the ECX register value, i.e., the counter reaches the value zero.
