title: MIPS I instruction immediate field
body: <p>The field is used by arithmetic and conditional branch instructions.</p>
  
  <p>First question is:</p>
  
  <p>What would be the range of values which can be stored in an immediate arithmetic instruction and conditional branch? </p>
  
  <p>Second is:</p>
  
  <p>if a MIPS processor has 64 registers, how would you change the immediate instruction format to reference these registers? How would I draw and label the format?</p>
