The Intel Pentium supports both the pure segmentation and segmentation with paging.  In Pentium system, the cpu generates logical addresses and give it to the segmentation unit. the segmentation units produces a linear address to for each logical address. The linear address is then given to the paging uint., which in turngenerates the physical address in the main memory. Thus the segmentation and paging form the MMU.
