Figure 2.3. Address Translation
SEGMENT REGISTER USAGE
The main data structure used to organize memory is
the segment. On the 80376, segments are variable
sized blocks of linear addresses which have certain
attributes associated with them. There are two main
types of segments, code and data. The simplest use
of segments is to have one code and data segment.
Each segment is 16 Mbytes in size overlapping each
other. This allows code and data to be directly ad-
dressed by the same offset.
In order to provide compact instruction encoding
and increase processor performance, instructions
do not need to explicitly specify which segment reg-
ister is used. The segment register is automatically
chosen according to the rules of Table 2.3 (Segment
Register Selection Rules). In general, data refer-
ences use the selector contained in the DS register,
stack references use the SS register and instruction
fetches use the CS register. The contents of the In-
struction Pointer provide the offset. Special segment
override prefixes allow the explicit use of a given
segment register, and override the implicit rules list-
ed in Table 2.3. The override prefixes also allow the
use of the ES, FS and GS segment registers.
There are no restrictions regarding the overlapping
of the base addresses of any segments. Thus, all 6
segments could have the base address set to zero.
Further details of segmentation are discussed in
Section 3.0 Architecture.
