Well AOS4 doesn't belong to AEon and ACube's version of the Minimig doesn't run AOS4 and was featured by A-Eon too.

You really think they would invest so much money in expensive Linux board?

It seems this board has generated more interest than the X5000.

Well, the majority(?) could argue themselves into buying a 700 euro computer if the specs are semi reasonable up to date.
Shelling out 2000-2500 for x1/5000 stops people dead in their tracks. And I belive some consider 440/460 to be too old/picky about what hardware addons, ram you can use etc.

So having a "reasonably priced" using more "off the shelf" accessories could entice more people to make the leap.

"OK-ish speed", "720p video playback". The latter is a bit ambiguous, doesn't say anything about codec etc. For sure this CPU is not close to the much higher clocked G4 7447A CPU's with Altivec and working H/W FPU, who plays most x.264 720p streams in full speed, full size, with no frame drop. It's unrealistic that this board could do this (at least from CPU). I'd say that performance wise, Kronos is probably winning the cake by putting it on par with the Pegasos2:

So compared to a Pegasos2 it is:
- 10 years later
- 2x the price

@TRIPOS

I will arther wait for actual benchmarks.

If all the stories about "industrial users" for Sam440 or Sam460 are true, it could be another part of ACube's industrial product line.

Examples:

http://www.acube-systems.biz/index.php?page=hardware&pid=4

It is a bargain compared with other boards around the same CPU:

Tabor the name

Tabor was the name of a mountain in the holy land, one of the few victories of the crusaders where fought at Mount Tabor and inspired people in Europe using this name (Germany: Montabaur, Bohemia: Taborites)
https://en.wikipedia.org/wiki/Mount_Tabor

Some people believed Jesus went to heaven from the top of Mount Tabor

Eh, of course. Linux is a SMP capable OS. Would be strange if it didn't!

and the new SPE (Single Processing Engine)

"Single Processing Engine"?

What we are talking about is the FPU unit in this chip that simply is incompatible with the normal FPU's used in the Book-E/PowerISA specification (it's not compatible with the IEEE754 standard).

As far as "Linux works with this", there is much info and additional references for you to read in this thread. It seems "it works" by simply ignoring this part of the chip, and letting the CPU handle all FPU operations in S/W.

As has been mentioned earlier, the former Debian PowerPCSPE maintainer called it "braindead". I don't know about that, but it seems to have been some kind of brain spasm over at Freescale when this core was designed. In the later core that followed this one, the e500mc, Freescale corrected this by reinstating the "classic" FPU, and the SPE, SPESFP, and DPESFP are all removed.

Quote:

This IS a very good reference for the OS4 implementation!

No, not in any way!

OS4 is striving for Amiga compatibility, SMP breaks this. And the best way for OS4 to deal with this "special" FPU is probably to ignore it just like Linux does, and letting the CPU take care of FPU emulation in S/W.

Well, Cyrus, Nemo, Tabor - all names from Jules Verne novels...

Sure, Tabor originates in religious texts, but A-Eon´s inspiration is clearly based on Verne (eg. see Tabor Island).

Tabor still nice city in the Czech Republic.

From what I see on picture(s): P1022 1.2 GHz (2x e500v2 cores) 1x PCIe x16 (2.0?? x16/x4) 1x RAM (DDR3) 2x SATA 1x DVI?? (from integrad GFX: DIU LCD controller; can´t see details of this port between serial and audio) Audio (again integrated via I2S of P1022 SoC) ?x USB 2.0 1x Serial port LAN port?? (next to USB)

Nope.
More likely a T10XX, probably T1022.
PCI-e X16 with 4 lanes, yes.
1X RAM, yes.
2X SATAII, yes (that is all it can support).

DVI? What the heck is that doing there?
Audio, yes the sound is probably connected the I2S
(its what Freescale told me would be appropriate).

USB # who knows, but it could have two or more LAN connections.

If I read Christian Zigotzky´s threads on Freescale forums correctly, plain PowerPC application also work in SPE version of Linux.

@Zylesea

Five pages already. A modern MicroA1 if I do say so myself.

BTW, what's with that old fashioned RAM? Green went out last decade.

What's that exactly?

Of course it isn´t. It offers better integer performance than 460EX, two cores and rich features on the SoC (SATA, USB, LAN, audio, GFX etc.). Only FPU is weak (when using native applications) or sloooooooow (emulated).

I´m sure we will see some real application benchmarks until it is on sale for all to decide for themselves.

Which software makes heavy use of the FPU? Why would A-EON opt for a such a motherboard CPU setup?

Blender, lame, 3D games like Quake.


What will work more or less OK with slow FPU (based on my WinUAE/OS4 experience): web browsing, video playback, (most) emulators and replacement engines.

At time when motherboard design started, they probably hadn´t other choices.

@AmigaBlitter

GPU accelerated video decoding/playback. Not very usable when discussing CPU performance.

Let's see the CPU do the number crunching instead!

@pavlor

I don't understand that chooice if this is true.

Why choosed the p version instead of the T?
