SEGMENTATION HARDWARE

An execution to map two-dimensional user-defined addresses into one-dimensional physical addresses. This mapping is affected by means of segment table. Every entry in the segment table has a segment limit and a segment base. The segment base contains the starting address wherever the segment resides in memory, while the segment limit specifies the length of the segment.

A logical address concise of two parts: an offset and a segment number,s into that segment, d The segment number is utilized as an index to the table. The offset d of the logical address ought to be between 0 and the segment limit. The segment table is basically an array of base-limit register pairs.
