Explain segmentation hardware?
We define an completion 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 base and a segment limit. The segment base holds the starting address where the segment resides in memory, where the segment limit specifies the length of the segment.
A logical address consists of two parts that are a segment number's, and an offset into that segment d. The segment number is utilized as an index to the table. The offset d of the logical address should be between 0 and the segment limit. The segment table is fundamentally an array of base-limit register pairs.
