Part B? pseudo code is fine. 3.3 Suppose a computer has Part B? pseudo code is fine.

3.3 Suppose a computer has an atomic swap instruction, defined as follows: Swap (vari, var2): (tmp = varl; varl - var2; var2 = tmp; ) In the above, tmp is an internal register. (a) Using Swap, develop a solution to the critical section problem for n pro- cesses. Do not worry about the eventual entry property. Describe clearly how your solution works and why it is correct. (b) Modify your answer to (a) so that it will perform well on a multiprocessor system with caches. Explain what changes you make (if any) and why
