A system is using segmentation without paging. • The segment table of the currently executing process has the following entries: Size Address 854 1251 1 140 240 810 3 100 145 4 400 2601 15 380 • The process is currently executing in segment 2. • References to segments other than the current segment are logical addresses of the form (s, w). • Self-references are of the form (BR, w), where BR is a base register and w is an offset. The register BR is loaded with the starting address of the current segment 2, and w is added to complete the physical address. Translate each of the following logical addresses into the corresponding physical address. If the address is illegal, enter a value of -1. Logical Address Physical Address (3,0) Blank 1 (4,250) Blank 2 (5,20) Blank 3 (6,10) Blank 4 (BR, 10) Blank 5 (BR,245) Blank 6
