Question: 6. What is the maximum memory size that can be addressed by 8086? 7. What is the addressing mode of MOV AX, [BX][SI]+55H ? 8.
6. What is the maximum memory size that can be addressed by 8086? 7. What is the addressing mode of MOV AX, [BX][SI]+55H ? 8. Calculate the physical address for fetching the next instruction to be executed, in 8086 ? 9. If the execution unit generates effective address of 43A2H and the DS register contains 4000H. What will be the physical address generated by the BIU? What is the Maximum Size of the data segment? 10. If a data segment begins at address 2400H, what is the address of the last location in the segment? 11. The register contents of 8086 is given below. CS=5000H,DS=8000H,SS=A000H,ES=B000H,SI=2000H, DI=6000H,BP=1002H,SP=0002H,AX=0000H,BX=5200H,CX=2000H,DX=2000H Calculate the effective address and physical address of the following instructions. a) MUL AX, [BP+BX8D] b) SBBAL,ES:[SI+5D] c) PUSH AX d) AND AH, [SI+42D] e) XOR DH, [DI+8D] f) DIV AX, [SI+2] 12. Assume SP=49FCH,AX=0F3AH,BX=F43CH,DI=0000H,SI=0000H and CX=0AH. Find the content of the stack and the stack pointer after the execution of the following instructions? PUSH AX PUSH BX POP DI
