What is the branch address if the address field of jump instruction contains -30 in the address field and instruction is designed with base register addressing mode? 32826 25657 32886 25717 CO and Architecture co-and-architecture branch-conditional-instructions addressing-modes + – Na462 asked Dec 2, 2018 • retagged Aug 1, 2022 by Shubham Sharma 2 Na462 505 views answer comment Share Follow See all 2 Comments See all 2 2 Comments reply Na462 commented Dec 8, 2018 reply Follow Share I have one doubt as the branch offset is added to program counter for getting the branch address but tin question they have added it to the base register why ?

0 votes 0 votes Addressing mode -- base register So branch address = 32856 + (-30) = 32826 Program counter is taken if it is PC relative addressing mode sachin486 answered Jul 31, 2020 sachin486 comment Share Follow See all 0 reply Please log in or register to add a comment.
