The Front End; Figure 1-5 The Intel Pentium M Processor Microarchitecture - Intel ARCHITECTURE IA-32 Reference Manual

The Intel Pentium M processor microarchitecture is designed for lower
power consumption. There are other specific areas of the Pentium M
processor microarchitecture that differ from the Intel NetBurst
microarchitecture. They are described next. A block diagram of the Intel
Pentium M processor is shown in Figure 1-5.

The Front End

The Intel Pentium M processor uses a pipeline depth that enables high
performance and low power consumption. It's shorter than that of the
Intel NetBurst microarchitecture.
The Intel Pentium M processor front end consists of two parts:
•
fetch/decode unit
•
instruction cache
