Techopedia Explains No Operation (NOP)
In some cases, no-op instructions are used for timing purposes. They can also help to deal with certain memory issues, or work in conjunction with a group of other instructions to facilitate some kind of end result. No-op instructions may be used for pipeline synchronization or to delay some type of CPU activity.
