Division in DLX programming

When we multiply or divide unsigned numbers, we must use logical shifts, as we will now see.

Example 1

  addui r1,r0,200   
  srli r2,r1,1 ;2^1  
  ;r2=200/2=100  

Example 2

  addui r1,r0,200   
  srli r2,r1,2 ;2^2  
  ;r2=200/4=50  

Example 3

  addui r1,r0,200   
  srli r2,r1,3 ;2^3  
  ;r2=200/8=25
