Wait, I've been corrected on Moo and via PM that XCore tools are closed. You'd need to have XMOS developers do a port. I think that was a statement of XMOS employee made in a thread eons ago. Looking for it.

There's two different aspects to keep in mind here: Developing for it and OS support for using the core. The protocol for talking to the chips over the JTAG pins are well documented, and so to load software onto Xena and use it requires just writing a device driver to do the transfer.

To develop for it, you obviously need a few more tools, and it'd be nice to have them available natively, though not as critical. But go look at their site. The source for *most* of their tools are available for download, and are adaptations of "standard" OSS tools like gcc, gdb etc..

There are some parts (most notably the XC compiler) that are not open source and would require cooperation from XMOS to port. But however nice to have the closed source tools (and the IDE etc. for those who care about IDE's - I don't) would be, they are *not* necessary.

You can develop for XMOS chips using plain C plus some small ASM wrappers for things like starting threads (half a dozen instructions to set up the thread) and using channels etc.. The required ASM is well documented in their manuals.

OK, thanks for further explanation. Next FAQ will be about XENA/XMOS, right? May we have this question asked: what kind of support can we expect for XMOS under OS4.x

A-Eon site still say, "you won't have to wait until summer".

I think this true! People say no updated the site, but because they work so hard assemble cases, motherboards, install the OS4, and things. No time work the website update people.

Shipping the X1000 in just weeks now!!

That's silly.

Clearly you don't need a senior system developer to be designing web pages.

At the very least, establishing a landing page provides contact information and legitimizes a business opportunity.

That's only good for single thread, correct?

good news for the gfx card. ati r700 support is quite a nice surprise.
there will be hardware acceleration for 3d ? or just 2d?

too bad about smp.. but well if its planned for near future its ok i guess .. (i mean *near*)

any news about unicode support?

and memory protection and resources tracking .. when ?
so ppl won't laugh, looking at the stability of the whole thing..

Q. Does the A1-X1000 have proprietary BIOS or free BIOS? A. The A1-X1000’s BIOS is the Common Firmware Environment, or CFE.

I still have trouble believing in the impossible. So for now I'll assume they ported the one PowerPC implementation to something else or that perhaps this list is old and not updated.

As I just saw is already linked by gerograph :

@ddni:

Kickstart on the CF card sounds interesting. It might be a possibility, but we must remember that loading a bunch o' files from a CF card is slower than loading it from a good high-speed disk.

Quicker to spot the similarities...

1. they are both motherboards.
2. they both have CF slots

errr I am drying up now...

No that is incorrect. You can't start new threads from plain C. But the assembly required to start additional threads is documented in their manuals. It takes half a dozen or so instructions in order to set up a stack for the new thread, set the program counter etc. and then finally start the new thread.. Wrapping those in a small function callable from C is easy.

This CPU would be really nice (although nearly impossible to get). Sure, it is 3 years old, but still probably the best PowerPC CPU ever made.

PA6T is on the same performance level as 970MP or Core Duo (not Core 2): 4-5 times faster than 440EP (and probably even much faster in FPU operations).

@pavlor
However, we should consider that A-Eon's partner might have access to a "remaining stock" of those (one of the tentative names that were made here, works with both Xmos and PASemi) considering that the X1000 wont sell HUGE numbers, they might have more than we will ever need...

when look at the X1000 image there can see a little of silver headspreader.look simular to the pa6 image.

I dont know if there are other PPC CPU that look simular to that.here can see the CPU in Big

really strange there are not much benches here.there was a announce that pasemi t join to eembc but no benches here.

http://www.eembc.org/press/pressrelease/070320.htm

btw here is a price for a Pa6 System.single price 4200$

and thats only a small card

http://www.xes-inc.com/press/070615.html

http://www.xes-inc.com/Products/XPedite8000/XPedite8000.html

so pa6 system seem not cheap

I agree. There are some scores on the coremark page, but it is really not so simple to interpret them (strange values for some CPUs, Pentium III 866 MHz two times faster than Celeron 1 GHz etc.). However, I estimate that PA6T performance is on the G5 level (thus two times slower than most Core 2 CPUs).

It seems that 1500 EUR for X1000 is not that much... (if it has PA6T)

>It seems that 1500 EUR for X1000 is not that much... (if it has PA6T)

if....

when read in the FAQ3

"""
We know exactly what parts we want, but we have to ensure that those parts are obtainable in the quantities we need, with suitable volume discounts and lead times. Once this process is complete we will have a better handle on the total system cost and be able to provide details of the initial retail price. Obviously the final price point is something that everyone wants
"""

there can only hope that they get a suitable volume discount to produce this.
outside the OS4 world i think the price for a Desktop System is extreme high.

The powerstation is not produce anymore but offer more power for sure and have lower price.

Yes and yes (if you meant 200W CPU...)

@bernd

Here is the picture without the masks.
