Because the Intel family of microprocessors is quite diverse, this text initially concentrates on
real mode programming, which is compatible with all versions of the Intel family of microprocessors.
Instructions for each family member, which include the 80386, 80486, Pentium,
Pentium Pro, Pentium II, Pentium III, and Pentium 4 processors, are compared and contrasted
with those for the 8086/8088 microprocessors. This entire series of microprocessors is very similar,
which allows more advanced versions and their instructions to be learned with the basic
8086/8088. Please note that the 8086/8088 are still used in embedded systems along with their
updated counterparts, the 80186/80188 and 80386EX embedded microprocessor.
This text also explains the programming and operation of the numeric coprocessor, MMX
extension, and the SIMD extension, which function in a system to provide access to floatingpoint
calculations that are important in control systems, video graphics, and computer-aided
design (CAD) applications. The numeric coprocessor allows a program to access complex
arithmetic operations that are otherwise difficult to achieve with normal microprocessor programming.
The MMX and SIMD instructions allow both integer and floating-point data to be
manipulated in parallel at very high speed.
This text also describes the pin-outs and function of the 8086–80486 and all versions of the
Pentium microprocessor. First, interfacing is explained using the 8086/8088 with some of the
more common peripheral components. After explaining the basics, a more advanced emphasis is
placed on the 80186/80188, 80386, 80486, and Pentium through Pentium 4 microprocessors.
Coverage of the 80286, because of its similarity to the 8086 and 80386, is minimized so the
80386, 80486, and Pentium versions can be covered in complete detail.
