Data hazards are as different format:-
Instruction 2 depend on instruction 1 that caused by register 4 with RAW hazard.Instruction 4 depends on instruction 3 that also caused by register 2 with RAW hazard and so on.

7 [24 marks] Consider the following MIPS code segment that is executed on a 5-stage pipeline architecture that does not implement forwarding or stalling in hardware. (1) add $4, $1, $1 (2) add $7, $4, $9 (3) lw $2, 40($8) (4) sub $8, $1, $2 (5) sw $8, 80(S2) (6) sub $2, $8, $4 (7) lw S8, 2($1) (8) add $8, $4, S2 Identify the data dependences that cause hazards. You are to use the following format to inform each...
Computer architecture help: (60 points) The following instructions are executed on the 5-stage MIPS pipelined datapath. add r5,r2, r1 lw r3, 4(r5) lw r2, 0(r2) or r3, r5, r3 sw r3, 0(r5) (a) (20 points) List the data hazards in the above code. For each data hazard identified, clearly mark the source and the destination. For example you can say, there is a data hazard from instruction X to instruction Y on register Z. (b) (20 points) Assume there is...
The code chain below is executed on a data forwarding, 5-stage pipelined processor. Which of the following instructions will encounter a stall? Write the instruction number along with the number of stall cycles that instruction experiences. (Note the data forwarding) 1. add $4, $5, $6 2. add $7, $4, $5 3. sw $8, 0($7) 4. add $8, $8, $6 5. lw $6, 0($8) 6. add $10, $9, $8
(Computer Architecture MIPS Assembly) Using minimum amount of nops - rewrite the code segment below so it doesn't cause any hazards. You may not reorder the original instructions, just insert nop where needed. add $3, $2, $3 lw $4, 100($3) sub $7, $6, $2 xor $6, $4, $3
4. Suppose the MIPS code below is running on the pipeline processor we introduced in the course: Original code: Reordered code: 11: Jw $50, $a0(4) 12: sub $s1, $50, $s3 13: add $81, $si, $s2 14: lw $t1, $a0(8) 15: Jw $t2, $a0(12) 16: add $s3, $t1, $t2 a) List all Read-After-Write (RAW) dependencies in the code. Highlight them over the code above. b) Assume there is no forwarding hardware capability available. How many cycles it takes to run the...
c. The classic five-stage pipeline MIPS architecture is used to execute the code fragments. Assume the followings: Register write is done in the first half of the clock cycle; register read is performed in the second half of the clock cycle, Branches are resolved in the second stage of the pipeline and the architecture does not utilize any branch prediction mechanism Forwarding is fully supported Clock Cycle à 1 2 3 4 5 6 7 8 9 10 11 12...
1.Please use 5-stage pipeline to describe following MIPS assembly code in non-forwarding pipeline. lw $s0, 0($t0) add $s1, $s0, $s0 mul $s2, $s1, $s0 . 2.Please use 5-stage pipeline to describe following MIPS assembly code in forwarding pipeline. lw $s0, 0($t0) add $s1, $s0, $s0 mul $s2, $s1, $s0 sw $s2, 4($t0)
1. Given the following instruction sequence for the MIPS processor with the standard 5 stage pipeline $10, S0. 4 addi lw S2.0(S10) add sw S2,4(510) $2, $2, $2 Show the data dependences between the instructions above by drawing arrows between dependent instructions (only show true/data dependencies). a. Assuming forwarding support, in what cycle would the store instruction write back to memory? Show the cycle by cycle execution of the instructions as they execute in the pipeline. Also, show any stalls...
The classic five-stage pipeline MIPS architecture is used to execute the code fragments. Assume the followings: Register write is done in the first half of the clock cycle; register read is performed in the second half of the clock cycle, Branches are resolved in the SECOND stage of the pipeline and the architecture does not utilize any branch prediction mechanism Forwarding is FULLY supported. Assuming there is no dependence other than one(s) given in the code, show the pipeline diagram....
Hello, I need someone to help me solving this problem, please. ================ For the code sequence below: add $1, $2, $3 sub $4, $1, $5 and $6, $1, $7 or $8, $1, $9 xor $4, $1, $5 1) Draw the pipelined dependences. 2) Show the forwarding paths needed to resolve the data hazards.
