It depends on the question. Had it been mentioned that instruction uses relative addressing mode, then we have to use program counter for calculating branch target address. Therefore in this question, Base register content is 32856. Branch target address for jump instruction = 32856-30 = 32826. 1 votes 1 votes srestha commented Apr 30, 2019 reply Follow Share ok, thanks :) 0 votes 0 votes SuvasishDutta commented Apr 30, 2019 reply Follow Share Ok mam 1 votes 1 votes Please log in or register to add a comment.
