Consider a memory management unit that uses segmentation with: • the segment implicitly determined by the source of the VA (PC, stack access, or heap access), • 16-bit VAS, • all segments growing positive (not negative), • the following segment register contents: Segment Base (physical) Bounds (physical) Code 12670 27117 Heap 27142 40894 Stack 38467 53522 • all addresses are expressed in decimal. When the CPU pops a value at VA 3261, what PA will that be translated into? Enter -1 if the result is a segfault.
