  4. Lab 4 : C Operator Exercise • Leftshifta variable A to the left by 5 bits and store it in A. A = A << 5; • Rightshift a variable A to the left by 5 bits and store it in A. A = A >> 5; • AND, OR, and XOR two variables and store them into a third variable. z = x & y; z = x | y; z = x ^ y; • Change a variable into its negation. z = ~z;

  5. Lab 4 : Virtual Memory • What to implement (vmem.c) • create_address_space() • map_page() Optional: • map_shared_page() • pfault() • Where to start with • Start from reading ‘mem.h’ • Each function in vmem.c has headers in mem.h which has comprehensive comments on what to do.

  6. Lab 4 : Virtual Memory • Useful Physical Memory API functions • Headers provided in mem.h, implementations provided in pmem.c • allocate_physical_page() • dereference_physical_page(unsigned intppn) • Debugging Tools • gdb debuggers • Function : dump_physical_memory()
