In assembly
1.What is the effect of the following instructions executing ona modern x86 64-bit system (describe what happens and the finalcontents of the registers involved)? Can you obtain the same endresult using only two instructions, and no other registers?
PUSH RAX
PUSH RBX
PUSH RCX
XOR RAX,RAX
XOR RBX,RBX
XOR RCX,RCX
POP RAX
POP RAX
POP RBX
2. What is the purpose of a segment register in protected modememory addressing?
3. For a 32-bit Pentium4 descriptor that contains a base addressof 01000000H, a limit of 0FFFFH, and G=0, what starting and endinglocations are addressed by it? (also see Segmentation andPagination Diagrams in BlackBoard, Other Reference Materials).
4. If DS=0105H in protected mode, which descriptor entry, table,and RPL are selected? (also see Segmentation and PaginationDiagrams in BlackBoard, Other Reference Materials).
5. What is the purpose of the TLB located within the Pentiumclass microprocessor?
