This is all the info

Consider again the datapath in Figure 1 and the program code in Listning 1 on the last page. For each of the code lines 3 and 4, when Inst has the corresponding machine code value of these code lines, state the values of the eight signals marked as black filled circles. If the signal has a uniquely defined value, (independent of the loop iteration) state that value as a hexadecimal number. If the value is always located in a specific register, (e.g. $t0) then state the register name (e.g., $t0). Otherwise, state that the signal value is unknown.
