Consider the two designs D1 and D2 for a pipeline processor. D1 has 5 pipeline stages with execution time of 4 ns, 3 ns, 5ns, 3ns and 4 ns. While the design D2 has 8 pipeline stages each with 4ns execution time. The buffer delay for both designs is 1 ns. How much time can be reduced in using design D2 over design D1 for executing 100 instructions?
Assume a classical RISC pipeline with regular (not delayed) branches. This pipeline has five stages: Instruction Fetch (IF), Instruction Decode (ID), Execute Instruction (EX), Memory Access (MEM), and Writeback (WB). You may assume that there are no resource hazards in this pipeline, but data hazards may exist. Draw a timing diagram that shows the execution of the following instructions in this pipeline. Assume that R1, R2, etc. are registers while A, B, etc. are memory operands. The first operand is the destination while the second operand is the source. The numbers on the left are the addresses of the instructions. BRA is an unconditional branch to a target address 120.
Given three instructions below: Sub $2, $1, $3And $12, $4, $5Or $13, $6, $2 Modify the pipeline machine below (by adding the forwarding related lines and components) so that it can resolve the above data hazard of the third instruction (or $13, $6, $2). Please note that your modification should be just enough to resolve the given data hazard. Any additional modification (i.e., it does not involve the above data hazard) will result in a penalty. show your in-between work or explanation.

We have a program of 10^6 instructions in the format of “lw,add,lw,add,…”. The add instruction depends only on the lw instruction right before it. The lw instruction also depends only on the add instruction right before it. If this program is executed on the 5-stage MIPS pipeline: a) Without forwarding, what would be the actual CPI? b) With forwarding, what would be the actual CPI

Q:..
In a 5-stage pipeline, where 2 stages are 150 ps each and 3 stages are 200 ps each, the latency of instruction execution in pipelined execution with no data or control hazards is Note that ps is 10-12 seconds 750ps 900 ps 1000 ps 600 ps Say an operation takes total 10 units of time and I decide to pipeline the operation by subdividing it into 10 stages. Theideal throughput of the pipelined operation would now be a. 1 completed operation every 10 units of time b. 1 completed operation every 1 units of time c. 1 completed operation every 5 units of time d. None of the above answers are correct
