Intel ® Pentium ® M Processor Microarchitecture
Like the Intel NetBurst microarchitecture, the pipeline of the Intel
Pentium M processor microarchitecture contains three sections:
• in-order issue front end
• out-of-order superscalar execution core
• in-order retirement unit
Intel Pentium M processor microarchitecture supports a high-speed
system bus (up to 533 MHz) with 64-byte line size. Most coding
recommendations that apply to the Intel NetBurst microarchitecture also
apply to the Intel Pentium M processor.
