An Overview of the Pentium 4's Architecture

Even though the Pentium 4’s pipeline is much longer than that of the G4e, it still performs most of the same functions. Figure 7-5 illustrates the Pentium 4’s basic architecture so that you can compare it to the picture of the G4e presented in Figure 7-4. Due to space and complexity constraints, I haven’t attempted to show each pipeline stage individually like I did with the G4e. Rather, I’ve grouped the related ones together so you can get a more general feel for the Pentium 4’s layout and instruction flow.
