Consider the following code that will be executed on the MIPS implemented in 5-stage pipeline, IF, ID, EX, MEM, WB, as in the text. add $3, $3, $4 1w $2, 100 ($3) add $2, $3, $6 (1) Assume the MIPS pipeline implementation is without data forwarding and no delayed slot, show how many cycles need to be spent to finish the code. To show the pipeline stalls, when and where, insert "nop" instructions into the code and also state the CPI for the code. (2) Now the pipeline is with data forwarding but without delayed slots, show how many cycles are needed for the code. To show the pipeline stalls, when and where, insert "nop" instructions into the code and also state the CPI for the code
