25. Reading from data memory

• Basic instruction to read integer from memory is called load word

  
       lw $t1, 4($t2)  # $t1 = Memory[$t2+4]
  
  

  Here, $t2 contains the base address, and 4 is the offset

• Note that there is a shortcut:

  
       lw $t1, 0($t2)
       lw $t1, $t2          # the same
  
       lw $t1, label        # $t1 = Memory[label]
       lw $t1, label + 4    # $t1 = Memory[label+4]
