Intel Pentium M (Dothan)

The Pentium M "Dothan" is the second generation Pentium M processor. The fabrication process was reduced to 90 nm and the L2-Cache was doubled to 2 MB. The second revision of Dothan Pentium M processors features a 533 MHz FSB and accompanies the Sonoma Centrino platform. Features 1.0 - 2.26 GHz clock speed 400/533 MHz FSB 170 Million Transistors 90 nm fabrication process 2 MB L2-Cache (Enhanced) EIST, Deeper Sleep XD-Bit (on most models) MMX, SSE, SSE2 instruction sets

Thermal Specifications

The max. Core Temperature is 100°C.

GCC Optimization Flags

You should use the following for GCC version 3.4.4 and later if you have a Pentium M:

-Os -march=pentium-m -pipe

For GCC version 3.3.5 and earlier use the following:

-Os -march=pentium3 -msse2 -pipe

Also, if you don't plan to use debugging information, then you can safely add the following to either of the above for a possible performance improvement:

-fomit-frame-pointer
