Suppose that a superscalar version of our 5-stage MIPS pipeline system contains the following functional units: 1 load/store unit, 1 branch unit, 2 integer units and 2 floating point units. The following instruction sequence is to be executed on this system:

                                        lui      $5,0×1234

                                        addiu  $5,$5,0×22

                                        sw      $5,0×4800($2)

                                        sub     $11,$4,$7

                                        sltu     $3,$9,$10

                                        sll       $12,$14,2

a) To avoid stalls, what is the maximum number of entrys required for a centralized instruction window to handle this instruction sequence?

b) If reservation stations are used instead of an instruction window, how many reservation stations are required for the system?
