Consider the following duration for each stage: IF - 286 ID = 196 EX (addition) 383 EX (subtraction) = 389 MEM = 182 WB = 332 Now answer the following questions: By how many ns the single cycle datapath clock period is greater than the 5 stage pipeline clock period? Only write the value, no need to mention unit For a single cycle datapath, what is the duration to execute 3 sub instructions, 6 lw instructions and 1 add instruction? If we were to build an architecture where only R type instructions will be executed and design the pipeline according to that, how many clock cycles would be needed to execute consecutive 66 R type instructions (without any dependencies)?

You are given snapshots of the MIPS pipeline from two successive cycles. For each figure, fill in all the relevant information in each stage, corresponding to the instruction in that stage at that cycle. Remember to specify clearly how control signals are set. Assume $x contains x * 100 (e.g. $1 contains 100). MIPS instructions used: add rd, rs, rt rd = rs + rt or rd, rs, rt rd = rs or rt lw rt, I(rs) rt = Mem[rs + I] (load word) sw rt, I(rs) Mem[rs + I] = rt (store word)

How do stalls impact the performance of a pipeline, and what techniques are used to minimize them?
MIPS instructions classically take five steps: IF, ID, EX, MEM, WB. A certain MIPS pipeline has the following properties: - IF: 1 cycle - ID: 1 cycle - EX: 1 cycle for A type instructions, 2 cycles for B type instructions, 3 cycles for C type instructions. МЕМ: 1 суcle WB: 1 сycle EX stage of the pipeline has three separate datapaths, to accommodate for the various cycle counts. A-type instructions B-type instructions B-type instructions C-type C-type C-type instructions instructions instructions Run the following instruction sequences through this pipeline with and without forwarding (Assume full data hazard, meaning each instruction depends on data that was produced by the previous instruction, and assume no load/store instructions): a) AAAAAAAABBBBBBBBCCCCCCCC b) АВСАВСАВСАВСАВСАВСАВСАВС с) АСВАСВАСВАСВАСВАСВАСВАСВ
Consider a datapath with 6 stages. Operation times/delays associated with each of these 6 stages are shown below: Register Write Back Instruction Instruction Execute 1 Execute 2 Data Access Fetch 200 ps Decode 100 ps 150 ps 150 ps 200 ps 100 ps Answer the following questions: a) What is the shortest possible clock period for single-cycle, non-pipelined implementation? What is the shortest possible clock period for pipelined implementation? How long will it take to execute 5 instructions on single-cycle, non-pipelined implementation? How long will it take to execute 5 instructions on pipelined implementation? Assume that no pipeline hazards are encountered while executing these 5 instructions. How long will it take to execute 5 instructions on pipelined implementation? Assume that there are 2 pipeline stalls (due to hazards) while executing these 5 instructions. b) c) d) e)

The instruction “addi” is an I-type instruction that can be executed using the Single-cycle datapath without modification. Answer the following question: (a) Give values of all control signals needed to execute this instruction on the single-cycle data. For example: addi $t2, $S2, 3.
Which of the following statements are correct? Allowing jumps, branches, and ALU instructions to take fewer stages than the five required by the load instruction will increase pipeline performance under all circumstances. Trying to allow some instructions to take fewer cycles does not help, since the throughput is determined by the clock cycle; the number of pipe stages per instruction affects latency, not throughput. You cannot make ALU instructions take fewer cycles because of the writeback of the result, but branches and jumps can take fewer cycles, so there is some opportunity for improvement. Instead of trying to make instructions take fewer cycles, we should explore making the pipeline longer, so that instructions take more cycles, but the cycles are shorter. This could improve performance.
What would happen if an instruction was disobeyed, and why would that be the case? In the following scenarios, a TLB that is maintained by software is more efficient than one that is handled by hardware:
