title: Pipelining with bypassing
body: <p>I am trying to understand the concept of bypassing by reading the following slide<a href="https://i.stack.imgur.com/PBRvu.png" rel="nofollow"><img src="https://i.stack.imgur.com/PBRvu.png" alt="enter image description here"></a></p>
  
  <p>Bypassing is reading a value from an intermediate source. What does the arrow stand for?, does it mean that X is executed after M in the sequence?. How does it work?</p>
