I doubt adding the xmos chip to the board raise the cost that much, the reason it cost this much is largely the small production run and I guess the CPU and OS4 development costs.


In parts, may about 15 USD. Some people have mentioned an increase in design complexity, I don't really agree with that. There's nothing to it. I doubt it had anything to do with causing the project to be delayed. For sure there's some work to be done on the software side of the fence, but given ssolie's last conference, i get the impression that support will be minimal, if there's anything at all.

XC, on the other hand, is similar to C, but it has easier ways to set up parallel threads and access I/O.


Yea, it's really slick and very intuitive.

Clearly the XMOS chip is on the motherboard because the Military (UK and/or US) had a specific use for such a device and since Verisys can make a few quid slogging it to the Military.  That's why they threw it on for not much extra money...

Perhaps it's for a drone that won't land when you muck up the GPS....

It's a fair comment that the price of XMOS is pretty irrelevant overall.

The chip itself, the sockets, support components etc may seem cheap, but when you start piling up all those "little" costs on top of each other...

But more importantly, and aside from components costs, added complexity means longer R&D and testing time (all done by an external firm on a consultant basis AFAIK, charging money for their time, unlike when, say, bPlan or Acube are doing it in-house for themselves) and potentially a more expensive PCB with more layers. This can be a major contributor to the end-user price tag, especially on extremely low volume projects, where *all* R&D and testing costs would have to be divided on just *a few hundreds* of units.

So I hope there is a plan for it, that there is an obvious point (at least obvious to *themselves*, since *nobody* outside seems to be able to come up with an idea where this makes sense), if not, then I would label it as a design flaw that played its part in putting the consumer price tag way out of reach for most potential customers...

If I had to guess, I'd suggest that perhaps the intended purpose of the XMOS chip is to allow the signal specification for the "xorro" slot to be customised from software. A customisable geek port that you can rewire using code, maybe?

I agree.

But who will do it? I mean designing and manufacturing the custom PCB-things...? And for what purose that couldn't be done by existing USB/PCI devides?

Yes, maybe those people was indeed the target audience...?

Good for a PC on a stick with software so that it works kind of like the old Siamese system maybe?

I'd be surprised if anyone did anything with it at all considering that there's been nothing stopping people interested in xcore microcontrollers from having a go at it for the low price of 100 USD with kit directly from XMOS. We've had what, two years now since this was all announced? I've seen nothing from the hobby hackers.

You obviously haven't been paying attention then.

We've had several interesting projects created with XMOS hardware.

But Piru is right, there is not enough bandwidth for emulating hardware as complex as a 68K.
I, myself, was looking at 6809 emulation with this hardware (closer to its capabilities).

Really, the Xena port is more of hacker oriented I/O port.

Examples? And please don't refer to stuff on the xcore website project directory as those have nothing to do with the A1X1K.

Is it really? What's hacker friendly about a PCIe connector?

Sorry, but the only projects I have any interest in have nothing to do with the X1000.

Have you actually looked into XMOS programming?
Its not just hacker friendly, its relatively easy to use (and quite flexible).
Its just not that fast.

Yes, I used the XS1L1 in a commercial product, where I designed the hardware and wrote the firmware. I'm very familiar with it.
