a.
Explanation of Solution
Miss penalty:
- The term “p” denotes misprediction probability.
- The “TOK” denotes time for execution of code without misprediction.
- The misprediction penalty is denoted by “TMP”.
- The average time to execute code as a function of “p” is shown below:
Tavg(p) = TOK + pTMP
- The equation for miss penalty is shown below:
TMP = 2(Tran - TOK)
- The “Tran” denotes average time for random pattern...

int abs(int x)
{
}
return x > (sizeof(int)*8-1);
int comp = x mask;
return comp;
}
A. What bit pattern does mask have, as a function of x?

results?
D. For the cases where they produce different results, how are the two
results related?
E. Show that with the addition of just one single arithmetic operation
(any C operation is allowed) that you can fix opt abs. Show your
modifications on the original code. (You can just provide the line that
you will add).
F. Are there any values of x such that abs returns a value that is not
greater than 0? Which value(s)?

Priscilla suggests that they should use the execution times of the algorithms as criterion; but Julius insists that they should use the number of statements the algorithms execute as criterion. Discuss the reasons why both criteria they are considering are not good for comparing algorithms; and recommend an ideal solution/criterion that Priscilla and Julius should rather use for comparing algorithms.arrow_forwardPROBLEM 21 - 0517: Write a subroutine which computes the roots of the quadratic equation a,x2 + a,x + a, = 0 according to the quadratic formula: X12 = (-az/2a,) + V[(a,/2a,)2 – (a,/a,)) (= [{a, + v(a?, - 4a,a,)} / 2a,]) (START SUBROUTINE QUAD COMPUTE, DISCRIMINANT (DISC) DISCarrow_forwardPROBLEM 24 - 0578: (a) Water flows into a tank at a constant rate Q.
