2. Use the following MIPS code for this problem: sub $2, $1, $3 add $1, $3, $2 or $1, $1, $2 and $1, $3, $:3 a. b. c. Identify which instructions and registers have data hazards. What type of data hazards are they? Schedule the code in the 5-stage MIPS pipeline without forwarding (only use stalls/bubbles). Clearly label your figure to show clock cycles, pipeline stages, etc. Schedule the code in the 5-stage MIPS pipeline with forwarding. d
