i am sharing you a question from the subject modern micro processor 8086
1) Assume that the physical address for a location is 0046CH, suggest a possible logical address ( answer is 0042:004C)
( kindly show all calculations in proper steps and label steps as 1, 2, 3 and so on and plz also tell its vice virsa, how to find physical address from logical address with same calculations )
2) I am sharing you some commands along with their addressing modes kindly tell how to read them in simple words
for example in (a ) part we will read as " take the value from DS and save it to AX" in this way kindly write each instruction plz do it properly
a) MOV AX, DS - Register addressing mode
b) MOV BX, 5678H - Immediate addressing mode
c) MOV CX, [3000] - Direct addressing mode
d) MOV AL, CH - Register addressing mode
e) MOV [DI], BX - Register indirect addressing mode
f) MOV AL, [BX] - Register indirect addressing mode
g) MOV DX, [BP+DI+4] - Based indexed with displacement mode
h) MOV CX, DS - Register addressing mode
i) MOV [BP+6], AL - Based addressing mode
j) MOV AH, [BX+SI+50] - Based indexed with displacement mode
k) MOV BL, [SI]+10 - Indexed addressing mode
l) MOV [BP][SI]+12.AX - Base relative plus indexing
