"All" Linux needs is things like:
- Memory protection
- Hopefully a FPU
which is all provided fairly nicely by many families of CPUs including
IA-32, MIPS, ARM, PPC, Alpha, 68030 (and greater), SPARC.
There have been some rumors that Transmeta's chip may be somewhat "optimized
Rumor only... The only thing that appears clear is that they are doing CPU
At any rate, in order to do a "scaled down" Linux system is not particularly
dependent on the CPU, but rather on the overall system.
The fact that IA-32 "accessory hardware" such as motherboard,
SCSI/IDE/Serial/Parallel I/O controllers, and video cards are widely
available deployed in the "Windoze world" results in their being cheap.
In contrast, a StrongARM-based system may use a dirt-cheap CPU, but since
you don't have 15 vendors hawking motherboards, the secondary hardware is
much less available and relatively more costly.
Design and build an 8-chip SMP motherboard using $25 MIPS CPUs that uses PCI
and sells for under $500 and you'll see SMP MIPS get popular real quick now.
Design a "Linux chip" that requires a custom-built motherboard and nobody
Those who do not understand Unix are condemned to reinvent it, poorly.
