A.

Program Plan Intro

Memory aliasing:

  • It denotes a case where two pointers might designate to memory location that is same.
  • The compiler should assume that unlike pointers might be aliased for safe optimizations.
  • The program aspects that could limit chances for a compiler in generating optimized code denote optimization blockers.
  • If a compiler is unable to determine whether two pointers might be aliased, it should adopt that either case would be possible.
  • The possible optimization set is been limited in this case.

You are given a class that processes purchases for an online store. The class receives calls to: • Retrieve the prices for items from a database • Record the sold items • Update the database • Refresh the webpage a. What architectural pattern is suitable for this scenario? Illustrate your answer by drawing a model for the solution, showing the method calls/events. b. Comment on how applying this pattern will impact the modifiability of the system. c. Draw a sequence diagram for the update operation.
2. The memory management has contiguous memory allocation, dynamic partitions, and paging. Compare the internal fragmentation and external fragmentation for these three approaches. [2 marks] 3. Suppose we have Logical address space = 24 = 16 (m = 4), Page size=2² =4 (n = 2), Physical address space = 26 = 64 (r = 6). Answer the following questions: [4 marks] 1) Total # of pages ? 2) Total # of frames ? 3) Number of bits to represent logical address? 4) Number of bits to represent offset ? 5) Number of bits to represent physical address? 6) Number of bits to represent a page number? 7) Number of bits to represent a frame number / 4. What is translation look-aside buffers (TLBS)? Why we need them to implement the page table? [2 marks] 5. Why we need shared pages for multiple processes? Give one example to show the benefits. [2 marks] 6. How to implement the virtual memory by using page out and page in? Explain with an example. [2 marks] 7. We have a reference string of referenced page…
