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)

Using MIPS assembly Calling a Subroutine Make your multiplier code into a function, and call it from a main. You must pass the two numbers to be multiplied into your function using the $a0 and $a1 registers, and return the answer back to main using the $v0 register. Do not load from your .data section or store to your .data section inside the function. You may load from and store to the stack, of course. After the multiplied value has been returned to main, you should place it into a main memory location and then print out the result using syscall. A sentence like "5 times 6 is 30." should be printed out in the terminal.

In deeper pipelines a branch prediction is very important because many more instructions are in flight and a wrong prediction would waste more time and power than that in a shallower pipeline. Select the best answer. True False
CPI stands for clock cycles per instruction. Speedup from pipelining = (Number of pipeline stages) / (Achieved CPI ). Assume a 5-stage pipeline. Assume that CPI = 1 when there are no pipeline stalls (the ideal case). Now assume that every branch instruction causes a 3 clock cycle stall in the pipeline. Assume that for the program being executed 30% of executed instructions are branch instructions. What speedup from pipelining is achieved by this program?
Determine the effective CPI, MIPS rate, and execution time for this program. Consider two different machines, with two different instruction sets, both of which have a clock rate of 200 MHz. The following measurements are recorded on the two machines running a given set of benchmark programs: Instruction Count (millions) Instruction Type Machine A Arithmetic and logic Load and store Branch Others Machine A Arithmetic and logic Load and store Branch Others 8424 10 9824 Cycles per Instruction 1343 1243 4 a. Determine the effective CPI, MIPS rate, and execution time for each machine. b. Comment on the results.
Suppose that we are developing a new version of the AMD Barcelona proces- sor with a 4 GHz clock rate. We have added some additional instructions to the instruction set in such a way that the number of instructions has been reduced by 15% from the values shown for each benchmark in Exercise 1.12. The execution times obtained are shown in the following table. a. Name Execution Time (seconds) Reference Time (seconds) bzip2 700 9650 SPECratio 13.7 1.13.2 [10] In general, these CPI values are larger than those obtained in previous exercises for the same benchmarks. This is due mainly to the clock rate used in both cases, 3 GHz and 4 GHz. Determine whether the increase in the CPI is similar to that of the clock rate. If they are dissimilar, why?
