Segmentation Unit
- Segmentation Unit: Converts logical to linear address
- Check TI (table indicator) bit to see if its in the GDT (gdtr register) or LDT (ldtr register) (0=GDT?)
- Compute base address of segment descriptor from index in segment selector x8
- Add offset from segment selector to the base field of the segment descriptor to get the correct linear address of whatever you’re looking for
- Note: Because of the non programable register attached to the segmentation register you can skip the calculation of the address of the descriptor (first 2 steps)
