title: How do i calculate the size of a tag field?
body: <p>I'm revising for an exam and i've came across a question that I have no idea how to do, i've looked through my notes and cant seem to find anything on it, can anyone help me?</p>
  
  <p>Given a 64KB cache that contains 1024 blocks with 64 bytes per block, what is the size of the tag field for a 32-bit architecture?</p>
  
  <p>The question is only worth 1 mark so i cant imagine the answer is too hard, but i cant seem to find anthing on it.</p>
