title: Datapath for a jump instruction(MIPS)
body: <p>Recently, I have studied Datapath for R-type,load, store, branch Instruction,jump.
  On control signal session, </p>
  
  <p>-Jump-</p>
  
  <p>RegDst : don't care</p>
  
  <p>ALUSrc : don't care</p>
  
  <p>MentoReg : don't care</p>
  
  <p>RegWrite : 0</p>
  
  <p>MemRead : 0</p>
  
  <p>MemWrite :0</p>
  
  <p>Branch : don't care</p>
  
  <p>ALUOp : don't care.</p>
  
  <p>jump : 1</p>
  
  <p>I can't understand why RegWrite,MemRead,Memwrite have '0' value.
  I think these three signals have to be don't care, since none of the data flow Registers,Datamemory.
  Could you explain why they got '0' value?</p>
