1- How to read data from Memory location 0100 by using the figure ? MOV AX,0 0100 0102 0100 Address Bus Data Bus Instruction Pointer Decode Unit General Purpose Register AX Execute Unit Instruction Register a) O MPU generates the address 0100, then the content of 0100 is loaded into Instruction register thru Data bus. b) O Memory informs that it has the instruction address at 0100, then MPU generates this address to access, then instruction is loaded into Instruction register thru Data bus. Accumulator generates the address 0100, then the content of 0100 is loaded into Instruction register thru Data bus. d)O Instruction register generates the instruction address at 0100, then instruction is loaded into Instruction register thru Data bus. C) e) O MPU generates the address 0100 then accesses into Memory thru Data bus. Later on, memory delivers the content of 0100 into Instruction register thru address bus. f)Instruction register generates the address according to Instruction Pointer, then the content of 0100 is loaded into Accumulator thru Data bus.
