ZDNET UK: Transmeta’s Crusoe: How it works

“The chip relies on software smarts to save power while keeping
performance high.”

Transmeta is billing its Crusoe chip as the first smart,
software-upgradable microprocessor.

“Using a software element called Code-Morphing Software by
Transmeta, Crusoe chips transform instructions meant for other
processor types, namely x86 chips manufactured by Intel or Advanced
Micro Devices (AMD), to instructions that can be run by one of its
own TM3120 of TM5400 processors. This means that the chips can run
the Windows operating system and Windows applications on top of or
in place of Transmeta’s own Mobile Linux.”
