Consider a pipeline processor with 5 stages S1 to S5. We want to execute the following loops: while(i ≤ 1) {11, 12, 13, 14) where i = 0. Time(ns) taken by the instruction 11 to 14 for stages S1 to S5 are given below: S1 S2 S3 S4 S5 11 1 1 2 1 1 12 1 2 1 1 1 13 1 2 2 1 1 14 2 1 2 1 1 The output of 14 will be available after

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
We wish to execute a single LC-3 instruction that will subtract the decimal number 33 from R1 and put the result in R2. Can we do it? a. No, because the smallest number that fits 5 bits is -32b. No, because we don't have SUB instruction to subtractc. No, because the smallest number that fits 5 bits is -16d. Yes, we can do it with a single instruction.e. none of the above.
Algorithm A, Algorithm B, and Algorithm C perform the same task. On input of size n, Algorithm A executes 10500n instructions, Algorithm B performs 30n2 instructions, and Algorithm C executes the ceiling of (1/1024) * 2n instructions. Assume each instruction requires the same amount of time in each algorithm. Algorithm A is slower than Algorithm B when the size of the input is less than .... Algorithm A is slower than Algorithm C when the size of the input is less than .... Algorithm C is fastest of the three when the size of the input is less than ....
