Modify the single-cycle datapath by implementing the ‘load word indexed’ instruction (lwx). Below is the syntax and the encoding. The instruction below reads the word from memory address (t1+t2) and stores it in register t0. lwx $t0, ($t1 + $t2)unique t1 t2 t0 0 0opcode rs rt rd shamt functa) Explain the functional form of the instruction based on the register names. b) Explain the functional form based on the instruction fields. c) Draw the changes on the datapath diagram and highlight them so they're visibled) Give the values of the control signals.
