What makes PPC so great? What advantage does it have over ARM or MIPS? Have freescale magically added all the features that ia32 and amd64 got ages and ages ago? Can they even get their designs running at clocks to be considered competition?

Amiga community needs to show the world that PPC is alive! Both AmigaOS 4 and MorphOS are today PPC operating systems.


There are plenty of operating systems that are actually capable of doing something that run on PPC, some of them still actively support m68k.. netbsd. It's very possible to write code that can be built to run on different hardware platforms and operating systems these days. Writing generic tools in PPC assembly for AmigaOS would be a little be backwards...

"Same with AROS for PPC. PPC is a great place to be for developers. Its not the "commercial" pressure on it as on x86."


/me fails to see how a processor arch. links to commercial interests.... other than if that arch isn't commercially viable there won't be any hardware around that uses it.

You also have low focus on viruses and other lamer exterminators!


I don't think either OS4, morphos or AROS have any serious security functionality. The only reason you wouldn't get a "virus" would be that no one is interested in your tiny platform, they could better spend their time stealing credit card details from millions and millions of people (opposed to like 5 or 6 - people -) running Windows. I doubt any of the available browsers etc are all that resistant to attack, it's just no one has be arsed to check them out.

I wish that more people instead of ditching PPC...


IIRC Freescale still fund linux development for the PPC in some way or fashion. I think they gave the Debian m68k guys some coldfire boards too. But that would be because some embedded partner wants linux and not because freescale has any interest in hobbyists.

Alternative platforms are a hobby not a religion ;).

Which magic in ia32 and amd64 are you thinking about ? PPC is a modern and clean processor. If it was more popular, processors and compilers will be even better.


What makes the PPC any cleaner than ARM, MIPS, SPARC?,... Maybe ia32 is a mess but most of negative comments about it come from people that have no idea what the hell they're talking about. There are broken bits but most of the time that stuff is handled in the OS and simply doesn't matter to desktop users. Anyhow it's probably better to listen to people like Theo de Raadt et al. on what's wrong with ia32 opposed to passers by on forums that have uneducated axes to grind.

Whats good about ia32 and now amd64.... Number 1; hellava cheap. Number 2; Performance/Dollar, Pound etc ratio very high; Number 3; Lots of modern (read as fast) hardware around. Number 4: Did I mention its cheap?

-- Edit, forgot to mention what ia32/amd64 has that most don't

- Decent'ish hardware virtualisation support without breaking the bank.
- Hardware support for marking no executable pages. All ia32 makers seem to have done this including Via and Transmeta. In Linux at least this seems to be emulated for PPC and SPARC.
- Highspeed memory and processor interconnects within the same die.

blah etc blah

oh did I say.. it's cheap?
