Question

Two processes are concurrently evaluating the expression (a + b) (c + d) - (e/f). Insert wait(S) and signal(S) operations into the code to enforce correct execution. The semaphore S, must guarantee that the additions must be completed before being used in
the multiplication. Initialize the semaphore with the initial value.
Process 1:
tl = a + b;
Process 2:
t2 =c + d;
t4 = t1*t2;
t5 = t4 - t3;
t3 = e/f;
The positions of instructions are given as line numbers. Copy and paste wait(S) in the position where you would insert the wait operation. Copy and paste signal(S) in the position number where you would insert the signal operation. (Note: exact matching
needed, hence type correctly or copy and paste). Enter NA if nothing to insert (Do not leave it blank).
Process 1:
1.
P1-
2. t1 - a + b:
3.
P3-
4. t4 - t1*t2:

The Java Virtual Machine (and your computer’s assembly language) support a goto instruction so that the search can be “wired in’’ to machine code, like the program at right (which is exactly equivalent to simulating the DFA for the pattern as in KMPdfa, but likely to be much more efficient). To avoid checking whether the end of the text has been reached each time i is incremented, we assume that the pattern itself is stored at the end of the text as a sentinel, as the last M characters of the text. The goto labels in this code correspond precisely to the dfa[] array. Write a static method that takes a pattern as input and produces as output a straight-line program like this that searches for the pattern. Straight-line substring search for A A B A A A int i = -1;sm: i++;s0: if (txt[i]) != 'A' goto sm;s1: if (txt[i]) != 'A' goto s0;s2: if (txt[i]) != 'B' goto s0;s3: if (txt[i]) != 'A' goto s2;s4: if (txt[i]) != 'A' goto s0;s5: if (txt[i]) != 'A' goto s3; return i-8;

Develop a program in C to create three processes A, B and C. Job of these individual processes are as follows: Process A: Reads n numbers from the keyboard and counts the number of odd numbers in it. Then this count will be sent to the Process B. Process B: Reads the count from Process A and determines the fibonacci sequence of that count. This fibonacci sequence result will be sent to the process C. Process C: This process reads the fibonacci sequence from process B and sort the numbers in descending order.
There are many algorithms presented in this text that would lend themselves to beincluded as subprograms in the utils.asm file.

Consider a computer running a program that requires 250 seconds, where 70 seconds is spent executing FP instructions, 55 seconds for INT operations, 85 seconds for load/save operations, and 40 seconds for branch instructions. By how much is the time for INT operations reduced if the total time is reduced by 20%?
