Our single$-$cycle datapath implementation consisted of a sequence of operations that resulted in the successful execution of a MIPS instruction. Place these operations in the correct order. $1$st $[$ Choose $]$ Read the value stored in the PC register $2$nd Decode the instruction in the control unit and fetch operands from registers $($if necessary$)$ Perform the required operation in the ALU $($if necessary$)$ Load an instruction from memory into the IR register $3$rd Load or store information using Data Memory $($if necessary$)$ Store the result into a register $($if necessary$)$
