Question 1: Explain how logical to physical address translation works
This question asks you to illustrate organization of the x86, 4K, 32bit segmentation and paging mechanisms through a simple example. Assume that the hardware translates the logical address '0x803004' that is involved into a memory access in the data segment into the physical address '0x8004'. The physical addresses of the page table directory (Level 1) and the page table (Level 2) involved in the translation of this virtual address are respectively 0x5000 and 0x8000. The entry 1 of the Global Descriptor Table (GDB) contains the base of 0x1000000 and the limit of 2GBs. The DS register contains the value 0x8. Draw a diagram (hand drawn figures are sufficient, but need to be clear) representing the state of the GDT, page table, and hardware CPU registers pointing to the GDT and page table directory and the process of translation (similar to Figure 2-1 in the xv6 book but using concrete physical and virtual addresses and page table entries). Provide a short explanation.
