Hazards in example multiple cycle pipeline

• Structural: Yes

  • Divide unit is not pipelined. Any Divides separated by less than 25 cycles will stall the pipe
  • Several writes might be “ready” at the same time and want to use WB stage at the same time

• RAW: Yes

  • Essentially handled as in integer pipe but with higher frequency of stalls. Also more forwarding needed

• WAW : Yes (see later)

• Out of order completion : Yes (see later)
