1. This Question relates to the data path and its support of MIPS instructions. a. [10 points] Identify the portion of the data path used by the Instruction Fetch stage. b. [10 points] Identify the portion of the data path used by the R-format instructions. c. [10 points] Identify the portion of the data path used by the load/store instructions. d. [10 points] Identify the portion of the data path used by the branch instructions e. [10 points] Identify the portion of the data path used by the jump instructions 2. For a pipeline with 5 stages, this Question relates to the pipeline speedup: a. [10 points Find the pipeline speedup for a program with 15 instructions. b. [10 points] Find the pipeline speedup for a program with "non-stop" instructions. 3. [10 points] MIPS architecture does not support a "branch on less than" instruction. Let's call this imaginary instruction blt, and implement it as a pseudo instruction. Show how to do this
