title: Instruction execution latencies for A53
body: <p>I'm working on optimizing a function which uses floating point instructions.</p>
  
  <p>For bench marking I need to know execution latency of the instructions to know theoretical possible performance.</p>
  
  <p>I have found such manual for A57: <a href="http://infocenter.arm.com/help/topic/com.arm.doc.uan0015b/Cortex_A57_Software_Optimization_Guide_external.pdf" rel="nofollow noreferrer">http://infocenter.arm.com/help/topic/com.arm.doc.uan0015b/Cortex_A57_Software_Optimization_Guide_external.pdf</a></p>
  
  <p>But, I don't find any such doc for A53.
  Am I missing something?
  Is there any such optimization guide available for A53?</p>
