The logical address (0,137), (1,4000), (2,3600), the 0,1,2,5 in (5,230) represents the segment number, and the 137,4000,3600,230 represents the amount of displacement. The memory address 50K in segment number 0 indicates the starting address of paragraph No. 0, and 10K indicates the length of the segment. For the logical address (0,137), first find the segment number 0, Physical address = starting address + displacement, that is, physical address =50k+137=50x1024+137=51337. (Note 1k=1024)
for (1,4000), because the displacement is 4000>3x1024, it crosses the line and produces the interrupt signal.
for (2,3600), locate segment number 2, Physical address =70k+3600=70x1024+3600=75280
for (5,230), the segment number of the logical address 5> the table length 4, the crossing occurs, and the interrupt signal is generated.
