Generate a hold or stall signal when a dependency between consecutive instructions is detected,

  • If MAR and MDR registers are being used in consecutive instructions
  • If an instruction uses as operand the result of the immediately past instruction
  • Conditional branch, stop the conditional branch instruction in the decode stage until the result is ready (the instruction evaluating a condition is in the retire stage)
  • Unconditional branch, ¿something to take care of?
