textbook. Examine this ﬁgure carefully to see exactly where each signal is located (i.e. before or after
pipeline registers). After Clock cycle 5, Indicate the resulting register values in hexadecimal in the spaces
provided below. Assume all data memory locations contain the word address of the location. Assume that
each register contains a value equal to the register number prior to execution of this code. add $4,$3,$4 7 / 0
