For forward and backward branch instruction , these offset need to be signed :) If you are saying saying offset as a unsigned integer it implies that you data structure can be queue (increasing address ) . But in stack you need to have negative and positive offset forward and backward position of stack pointers !! 1 1 replyShare Digvijay Pandey commented Apr 18, 2015 reply Follow flag BASE-REGISTERADDRESSINGFor base-register addressing,the interpretation is the following:The referenced register contains a main memory address,and the address field contains a displacement (usually an unsigned integer representation) from that address.The register reference may be explicit or implicit.
