PLEASE SHOW ALL THE VALUES OF THE CONTROL SIGNALS THAT ARE ACTIVATED IN THE EXECUTION OF INS
(20 pts) Figure 1 shows the datapath for the single-cycle implementation of the subset of MIPS instructions studied in this course. On Figure 1, show the values of all the control signals that are activated in the execution of the instruction sw $ 30, 37($ 31), assuming that register 30 contains the two's complement representative of -10 (base 10) and register 31 contains the two's complement representative of 16 (base 10). Assume the PC is 0x20. (a) Give the hex representation of the command. (b) What is the sign-extended value and the left shifted values of offset? (c) Where (what address) is the data stored? (d) Show the control signals on Figure 1.
