(15 points) Below is a portion of a timing diagram showing resource usage under the "Original" PCP. Note that $\mathrm{t}1$ is the highest priority process and that the ceiling is set accordingly Notice the diagram shows the long chain of waiting that can arise with IPCP and the time $t1$ spends blocked by $t4,t3,t2$, and $t4$ again before it gets to run. a. (10 points) Please redraw this diagram illustrating resource access under Improved PCP. b. (10 points) Considering your drawing above, what impact does ICPC have upon the number of context switches? c. (10 points) What is the intuition behind your observation in (C)?
