Amiga & AROS A few moments ago, a woman appeared at my doorstep with a package for me. Since it was about 19:30, I was a little perplexed - this isn't a very usual time to be delivering packages. Also, this was a woman who I've seen walking around town before - she's a local. She handed over the package, and when I saw the note on top, I was even more intrigued: "From Trevor Dickinson, A-EON Technology".

On paper, it seems like a very good CPU. Does anyone know what the consequences will be for the Amiga OS? does this CPU offer greater functionality and performance than Intel CPUs? what is the advantage of this CPU?


It was a great cpu in its time (a few yeasr it would have attraced me stropngly) and today is still a nice one, ableit waaay to expensive and not really up to date.
The reason for OS4 to chose PA6T is plain and simply that it is a ppc and thus offers a big endian data type. And OS 4 is ppc/big endian only. A switch to x86/little endian for that OS is far from trivial if you want to keep backwards compability.
Diffrent to most other OSes OS4 shares structs between the OS and apps, if these dont match the same endianess you are in deep trouble. The same is true for MorphOS.
If the PA6T or any othe rppc is only a particuar choice, but generally the PA6T is a nice cpu, albeit not developed any longer and not my first choice (which Freescale 86xx or some QorIQ chip).
