The code in Part A has two data dependencies (R3 and R4), and can be resolved using forwarding and double-pumped register file. However, we still have control dependency for "beq" instruction. To solve the control dependency issue, we add a "nop" after the "beq" instruction, as showsn in Part B. Question: We would like to keep the pipeline full as much as possible and improve the performance. Can we reorder the instructions to avoid NOPs? If so, how?

For the whole question, pseudo-instructions are not allowed except “j target_label”and “jr ra”. One suggestion for assembly programming problems is that you can includecomments to one or a block of instructions. Consider a RISC-V assembly function func1. func1 has three passingarguments stored in registers a0, a1 and a2, uses temporary registers t0-t3 andsaved registers s4–s10. func1 needs to call func2 and other functions may call func1also. func2 has two passing arguments stored in registers a0 and a1, respectively. Infunc1, after the program returns to func1 from func2, the code needs the originalvalues stored in registers t1 and a0 before it calls func2. (a) How many words are the stack frames of function func1?(b) Indicate which registers are stored on the stack of func1.
Show examples of C code that explicitly do a read-modify-write operation on SAMD21 I/O pin PA02 to setthis bit in a PORT register, clear it in a PORT register, and toggle it in a PORT register. You may assumeit has already been initialized as an output. If possible, show an example of code that implicitlydoes a read-modify-write operation on this pin.
In some instruction sets, call and return instructions make use of a RR register to hold the return address rather than doing so on the stack. Show how the code in the above problem should be changed if call and return instructions used a RR register for return addresses rather than the stack. Don't change the program's function. 500 MOV R1, X 501 MOV R2, Y 502 MOV R3, Z 503 PUSH R1 504 CALL 550 505 POP R3 506 CALL 560 507 HALT · · 550 PUSH R2 551 CALL 560 552 POP R2 553 RET · · 560 PUSH R3 561 PUSH R1 562 POP R2 563 POP R1 564 RET
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 would you implement the EXECUTE state for the same novel ANDI instruction? Fill in the blank with one or more lines that would replace the one below it in the response box. Signals include the accumulator (AC), instruction register (IR), memory output data (mem_data), programme counter (PC), fetched operand field (operand), and memory write (MW), should you require them. If ex_andi=>state is less than fetch, then
1. If the AL register is storing the binary number 10010010, what will be the contents of the BX register in binary after the instruction "movzx bx, al"? What would be the contents of the BX register in binary if this instruction is performed instead: "movsx bx, al"? What happens if you set ECX to 0 before beginning a loop? Is LOOP an unconditional or conditional transfer instruction?
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.
5. Pipelined datapath has five stages, ie., instruction fetch (IF), decode (ID), execution (EX), memory (MEM), and write back (WB). It has a hazard detection unit. An instruction will be stalled at the decode stage if any of its operands isn't ready. Consider executing the following code on this datapath (1) At the end of fifth cycle of execution, what instruction will be in each of the pipeline stages? (If there is any "bubble" in the pipeline, please write "NOP" in the corresponding pipeline stage.) (5%) You must write the answer with the following format. instruction IF instruction lw $r2, 10($1) sub $r4, $13, Sr2 add $r5, Sr6, $7 and Sr8, Sr4,$r5 IF ID EX (2) If the datapath has a forwarding unit to resolve the data hazard, what instruction will be in each of the pipeline stages at the end of the fifth cycle? (If there is any "bubble" in the -pipeline, please write "NOP" in the corresponding pipeline stage.) (5%) You must write the answer with the following format: (D MEM EX WB.…

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?
Using graphical representation to show the forwarding technique cannot completely avoid the data hazard. How many stall cycles are there when the forwarding technique is used? What is the advantage of having the source register fields in a fixed location for each instruction in instruction pipeline design?
