Question A $(17$ points$)-$Course name $-$ Real time systems $-$ CPRE $558$

Consider a system with $3$ periodic tasks $T_1,T_2,T_3$ and three resources. Assign

suitable priorities and resource access patterns for these tasks, and answer the

following subquestions.

Note: Use the hypothetical scenario discussed in the class $($with task two tasks

and two resources$)$ as a template to show your answer.

Show the "execution sequence" that leads to deadlock using conventional

semaphore. Also, show the "wait$-$for graph" for this execution sequence.

Show the "execution sequence" using Priority Ceiling Protocol $($PCP$)$ that

avoids deadlock. Also, show the "wait$-$for graph" for this execution

sequence.
