Forwarding

• Recall that forwarding for the AbM pipelined implementation was done with the execute module

  • Two execute operands; had to check three paths for each operand (Mpacket, Rpacket, Wpacket)

• Forwarding within AbM VLIW

  • Still need to check three paths for each operand
  • Each path can now contain EUMAX instructions!!
  • Forwarding checks = three paths * EUMAX * 2 operands
