List the vаlues оf the signаls generаted by the cоntrоl unit for addi. For ALUop if you can remember the code then fine otherwise write whatever operation that ALU will perform in clear text.   Branch:MemRead:  MemToReg:ALUop:MemWrite:RegWrite:

(а)[2 pоints]Fоr аn instructiоn set аrchitecture (single non-pipelined) the R-type instructions take 700 ps, lw takes 950ps, sw takes 905ps, beq takes 705ps, and I-type takes 700 ps. What is the minimum clock period for this CPU? (Note in non-pipeline architecture we use a single clock period that is long enough to ensure that each instruction can be completed in a single clock period correctly).   (b)[4 points] If we are allowed to have different clock periods for different instructions what will the average time per instruction look like given the share of the instructions are as follows: [Hint: multiply the clock period of each instruction type given above with the percentage and calculate a weighted average] Please show the calculation. R-Type/I-type (without lw) = 52% lw =25% sw = 11% beq = 12%   (c)[2 points] What would be the speed up when we compare the timing of (a) with the timing of (b).
