Question
Please solve me this question, I have been struggling with it for so long :(
(a) Consider that two processes, P1 and P2, are executing concurrently. Both the processes share a standard variable named "Counter", having an initial value = 5. Find the final value of Counter and update tables below: Process P1 tries to increment the value of the counter. Process P2 tries to decrement the value of the counter. Update column Reg 1, Counter and Reg 2. The execution order of the instructions may be P1, P1, P2, P2. (Notes: Column P1 with value 1 is produce 1 slot and column P2 with value 1 is consume 1 slot) Time to tl t2 t3 t4 t5 t6 t7 t8 t9 t10 t11 P1 1 1 Reg 1 5 Counter 5 Reg 2 5 P2 1 1
