title: Looking for a way to sleep ( delay ) MIPS using QT SPIM
body: <p>i am trying to find a way to delay my program for a couple of seconds in MIPS. 
  I have seen some answers regarding syscalls in MARS but nothing works in SPIM. Any way to delay in SPIM ? thanks in advance. </p>
  
  <p>edit : im looking for a more convenient and smart approach, not like "write code that loops one million times" </p>
