The Application Register Set consists of the registers most
often used by the applications programmer. These regis-
ters are generally accessible, although some bits in the
EFLAGS registers are protected.
The General Purpose register contents are frequently
modified by instructions and typically contain arithmetic
and logical instruction operands.
In real mode, Segment registers contain the base
address for each segment. In protected mode, the Seg-
ment registers contain segment selectors. The segment
selectors provide indexing for tables (located in memory)

that contain the base address for each segment, as well as
other memory addressing information.
The Instruction Pointer register points to the next instruc-
tion that the processor will execute. This register is auto-
matically incremented by the processor as execution
progresses.
The EFLAGS register contains control bits used to reflect
the status of previously executed instructions. This register
also contains control bits that affect the operation of some
instructions.
