EA = PC + operand part after fetching instruction PC will be incremented by 2 Hence PC = A+2 operand part = B. Hence effective address = A+B+2. 4 4 replyShare priyanka manwani commented Sep 8, 2018 reply Follow flag why we are adding operand???since when did this started to happen?? can you please make a diagram of this 0 0 replyShare Saloni27 commented Sep 14, 2019 reply Follow flag @ashwina can you plzz verify the ans for this question? 0 0 replyShare Please log in or register to add a comment.
Best answer 2 2 votes Since the addressing mode is relative therefore EA=A+PC where A is the address of current instruction being executed therefore during execution of instruction A the pc contains A+2 as it is a 2 word instruction as soon as it gets location B then operand will available at A+B+2 Saloni27 answered Sep 14, 2019 • selected Sep 15, 2019 by dragonball Saloni27 comment Share Follow See 1 comment 1 1 comment reply debasish paramanik commented Sep 25, 2020 reply Follow flag Please correct it EA=B+PC 2 2 replyShare Please log in or register to add a comment.
