hardware OS4   hardware OS4 : Introducing Tabor and the A1222

Introducing Tabor and the A1222
A powerful, low cost, entry level PowerPC motherboard

San Francisco 19th October 2015


A-EON Technology Ltd is pleased to announce that Tabor, a new powerful, low cost, entry level PowerPC motherboard, which forms part of our A1200 series, is about to undergo beta testing.

As part of our drive to create more powerful lower cost, entry level hardware and expand the Next-Generation user base we commissioned Ultra Varisys to create a new PowerPC motherboard. The result is Tabor, a 170 mm x 170 mm mother-board based on a Freescale QorIQ P1022 32-bit e500v2 dual-core PowerPC processor running at 1.2 GHz. Prototypes have already been shipped to key developers and members of A-EON Technology’s Core Linux support team and, as a result, several Linux distributions are already up and running on the Tabor board. Working in cooperation with ACube srl, a beta test programme is about to commence, which is already over-subscribed.

The full system is designated the AmigaOne A1222.

I think by saying "cheap" (or low cost or whatever) are building a bit too much expectation. I doubt it will be less than 500 Euro after VAT.

@KimmoK

DDR3 uses a DOUBLE DATA RATE, so unless someone is being EXTREMELY thick "400MHz DDR3" should mean it's doing 800MT/s

How you got a multiplier of 3 is so far beyond me I can almost see it approaching from the other side.

Would love to finally have a dedicated OS4 machine.

This is the best news I have heard in years - finally I might be able to afford a new Amiga. MUST have OS4 running on it before I buy one though.

@KimmoK

The P1022 has a 36-bit physical addressing so I guess it can handle 64GB or RAM.

Topaz because it is a B-52 song, so it follow CBM codename.

Yeah, indeed, double means double, not triple, no matter what number follows...

How other systems use more than 4GB with 32bit OS:

The more common term for the memory is PC3-6400.

It will be interesting to see if SPD is implemented on this board.

1200 series ??

Hmm I somehow predict a "middle class" board coming too

My guess is it's gonna be called the A1252 (like in B-52)

Of course this is pure speculation on my part

Actually, I thought it was "PC3-6400".

I am not very technical, do the specs in the brochure confirm the FPU incompatibility?

one of the lead OS developers confirms that FPU has to be emulated (as already mentioned a couple of times)

I have gathered so far:

It seems emulated FPU is super slow on A1222. (1/30 of real FPU speed?)

But SPE optimized emulation is not that bad, even if it still is very slow. (1/10 of real FPU speed?)

I think there is no PPC FPU to SPE JIT anywhere, yet. Perhaps never will be.

SPE optimized/compiled version of SW is OK fast. (~1:1 of real FPU speed)


So vs SAM460, without optimized SW, all FPU using SW is slow.
-> Better to use non FPU versions of 68k SW. Unless petunia is updated for A1222.
-> Better to use A1222 optimized versions of AOS4.x SW.


I have not yet seen any plan of implementing some kind of JIT compiler for 4.x legacy apps.... ?
(Most likely not needed as main apps can be recompiled for SPE.)

you mean JIT for 4.X applications? I do not think that this will happen because of only few resources

Which one? And what exactly did he mention? "Emulation"? Or was it rather "replacement"?

@all:

It΄s much too early to discuss the topic "missing" FPU. Just wait and see how this special thing is handled.

then it would be heavy competition for some of Acubes products


Just remember:
- porting OS4 won't start before X5000 port is done
- porting OS4 does take time
- porting OS4 to this board has the extra FPU-hurdle built in

So all in all one cane say that Tabor won't be competition for Acubes products till 2018.

The re-availibility of the SAM460 might even be connected to this.

Depending on the price tag. This might be my first OS4 machine. (Not counting the OS4 classic running in FS-UAE).

Same here. I haven't yet got to AOS4 on FS-UAE, but it seems like a logical next step.
