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

0

Opcode rs rt rd shamt funt

a) Give the functional form of the instruction based on the register names.

b) Give the functional form based on the instruction fields.

c) Draw the changes on the datapath diagram.

d) Give the values of the control signals.
