Moobunny attacks everything. Sorry - that's unfair - Moobunny doesn't but it attracts a lot of very bitter people which do.

Moobunny's appeal is that it is a truly uncensored site but that does tend to have its own issues.

@ChrisH "how the XMOS chip interfaces with the X1000, perhaps someone with more time & experience could tell us what it will & won't be able to do?"

I tried. Put it is not too easy to understand.
But...

- It does have IRQ line to CPU, so I imagine it is able to connect with very low latency to the system. (far better than via USB etc.)
- PA6T might be able to "talk" directly with the xmos side just like yet another XCORE.

I wish they could send "empty" prototyping/developer board for xorro to every x1000 buyer that want's it...
(like this http://media.digikey.com/photos/Twin%20Industries%20Photos/MFG_7586-5100.jpg
or this http://www.knjn.com/ShopItemsPics/Board_Dragon-E.jpg , but with xorro connection.

Hello from Japan. Maybe you have heard of this site Moobunny. They X1000 and this project seems to attack Amigaworld website. http://moobunny.dreamhosters.com/cgi/mbmessage.pl/amiga/188000.shtml Some of the members are attacking it. The name and post it as a user authentication system looks lacking. Does anyone see this site before? Feud or available? Like below. http://moobunny.dreamhosters.com/cgi/mbmessage.pl/amiga/188020.shtml

The vocabulary used on moobunny should tell you plenty about the emotional level and manners of that site.

I'd agree with you, but then we'd both be wrong.

no worries my friend as the aforementioned site is not well respected.

More importantly, hope things are starting to be bearable after the horrific tragedy

I read the posts. The language would be rated R. Sounds like somebody very wired and way over the edge. Usually people that talk like that are very insecure and making a big effort to impress people. But I wonder how much truth there is in what they're saying. It gives a whole different point of view.

Great news!!
Hope everything will be well with that rev.2 board so they don't have to make a rev.3 which would take considerable time.

About moobunny: That site for idiots, by idiots.

Since when does the release of some schematics = production??!!

Another bad joke being played on Amiga land.

I'm liking the Xena interface. 16 bit multiplexed address/data, basically an 8086 interface. Tried and tested, nothing wrong with that (Zorro3 was a 32 bit version of the same).

Should be good for a few hundred MB/s of throughput, methinks. And the same interface is used to tell the PLD to program the XMOS via JTAG. Mesa like.

First order of the day would be to make a system where several programs can all upload tiny apps to the XMOS and have the XMOS follow the host CPU context switches. That would be cool.

When CPU is busy with other tasks, it obviously needs an interrupt to hop back to receiving data once the XMOS buffer is starting to fill up.

So efficient programming of XENA will require control of interrupts as well as user space programming for two architectures. Not simple, but potentially very cool.

@olegil

I like your thinking. I have been wondering if the XENA chip could be used to write
a "hardware" assisted debugger (I am not convinced it is a good idea yet though).

AFAICT, on the XCore side it's just a bunch of I/O lines, whereas on the CPU side it's the "Processor Local Bus", which is primarily used to attach a ROM for the firmware.

There isn't much technical info about the 1682 around, but one presentation I found (sorry, didn't bookmark) mentioned this bus to run at 33MHz. Which *may* be slow enough for the XCore to implement its end (i.e. pretend to be a memory-like device), although I am far from convinced (after all, each thread runs at a maximum of 125 million instructions per second, so bit-banging an asynchronous 33MHz protocol would at least be challenging....)

So assuming a protocol with one address cycle, followed by one data cycle, you are looking at 33MB/s, max. Which, of course, isn't much of a problem, seeing as it will still fill the XCore's memory in 2ms, but it *is* a far cry from "a few hundred MB/s".

@umisef (you just don't know how to spell unicef, do you? )

Hmm, missed those two important pieces of that puzzle. Bit of a disappointment, really. I'm used to PPC chips which can easily run at least 100MHz off the local bus.

But seriously? You're saying the chip won't be able to utilize it's power unless at least 4 threads are running anyway, meaning that you in any case have 125MIPS allotted to just handle that interface. (down to half that if you MUST use threads 5 through 8). Half full/half empty sort of situation if you ask me

Edit: Now, the GOOD news is, this made me look up some more facts about the XCore and I'm intrigued. From a technical point of view. As an embedded systems developer

Unless you use (?) the Local Bus to control the functions of Xmos
and let the I/O data be handled by the inline PCIe.

Local Bus as CP/M, PCIe as data paths.

P.S. XS1-L2 = 16 threads max.

Sounds like a good topic for a thread.

X1000

It seems there is now x1000 rev2 thread started also @xmos forums:

@Mechanic

How on earth would that help? You would need an external PCIe to localbus chip to get that data path into the XMOS chip anyway, and in that case you're stuck with two local bus interfaces. One to each core.

The news was about the Rev. 2 being in production. Because it was now in production they also decided to release the schematics.

The news was not about the schematics being release and everyone misinterpreting this as the board being in production, which I'm guessing you implied with your post
