Unformatted text preview: numbers to be trademarked. Instead, they coined the name “Pentium” using the the Greek root word penta as an indication that this was their fifth generation machine. Since then, they have used variants of this name, even though the PentiumPro is a sixth generation machine (hence the internal name P6), and the Pentium 4 is a seventh generation machine. Each new generation involves a major change in the processor design. End Aside. Over the years, several companies have produced processors that are compatible with Intel processors, capable of running the exact same machine-level programs. Chief among these is AMD. For years, AMD’s strategy was to run just behind Intel in technology, producing processors that were less expensive although somewhat lower in performance. More recently, AMD has produced some of the highest performing processors for IA32. They were the first to the break the 1-gigahertz clock speed barrier for a commercially available microprocessor. Although we will talk about Intel processors, our presentation holds just as well for the compatible processors produced by Intel’s rivals. Much of the complexity of IA32 is not of concern to those interested in programs for the Linux operating system as generated by the GCC compiler. The memory model provided in the orig...
