Just got this from production:
from previously posted layout...
This is a pretty serious signal processor application, but dropping the Zed on there makes it easy. We can plug a USB logic analyzer directly onto that Mictor connector, which has 16 signals and a clock from the uZed.
Rather than being cautious, I just plugged 24 volts into it, and the Zed lit up and ran Linux.

What does 'Z' do that a Raspbery Pi cannot?
Very nice!
Is there stuff under the uZed as well?
I calculated that (for us anyway) the assembly cost in small quantities on the uZed would exceed the price, so it's kind of a no-brainer if it will do the job.
Best regards,

Integrate two 600 MHz ARM cores and a screaming-fast FPGA onto one chip. And the Zed has Ethernet, flash, DRAM, USB, power supplies, all that stuff done and tested. It's a great way to do gear that will be built in fairly small quantities.
This app will do a lot of signal processing in the FPGA at 48 M samples/second.

It's not nice, it's beautiful.
No, just three rotary hex switches that set the IP address. The customer insisted on that.
Life would be great without customers.
All that DDRx ram and microSim and Ethernet and stuff is a nuisance to design and test. For a tad under $200, it's a bargain.
The Xilinx software is, as usual, a horror story, but it looks like we have things working now, namely a Linux app talking to the FPGA talking to pins on the interface connectors. As far as I know, there is *no such* reference design!

Well rapsi has that, but only one core.
any combination thereof.
But rapsi also has HD HDMI out, and audio out, etc...
That HDMI out is cool, as you can plug it into almost any modern monitor and make nice user friendly presentations. Something that is not so simple or needs extra hardware on other platforms. My rapsi even plays HD movies... Just imagine, when it starts up you can make it play the Highland background with cows grazing. with greener grass...

The chip has an integrated FPGA and a dual Cortex-A9
What it doesn't have is video and gpu, but you don't need that for crunching numbers

The yellow block is silkscreened. That's where they usually put the part number + serial number sticker.
#1 is mine. I'll scratch up the board to make it ugly enough that they won't swipe it and sell it.

Is there a small low-power single board computer that already has full audio (not just output), some ADC/DAC capabilities and things like that on board and runs a decent OS where one does not have to be a computer whizkid?
Oh, and decent mounting holes like the MicroZED. The Raspberry Pi is a bit pathetic there, only two holes for flimsy 2.5mm screws. One fall onto tile floor and it goes sailing.

The ZYNQ FPGA does have an on-chip ADC, brought out to the board-board connector. I'm using that in one of my self-test modes.
It's good for 1 MHz. It provides 16 bits, the low four of which are apparently noise.

I came across that a while back, thought they worked for you... They all look a bit like that MS windows background I have seen in places.
No, but Bernard Riondet is sort of an old friend. We never could find a good project to work on together, so he did his own thing. We did the master timing system for NIF, and then he apparently did the one for LMJ.

I think I recognize S2 and S3 for some reason. :)
Does it have a shell and Tetris installed?
Matt Roberds
Which did you complain about?
Yes. Me.
I did crank down the resolution for public presentation. The original is much better.
I have an open-top light tent in the back of the building, next to the north-facing windows. And a few boxes that work nicely as camera supports. The north light is a little blue, but Irfanview fixes that.
Works well enough. Show us some pics of your boards.

This is a much better board picture than the ones i had complained about. Did you find someone in your company to do them?

Sure, just as soon as i make one. I am still looking for the one i did over 40 years ago as a teen. (Just when i get a bit bored though, doesn't happen much.)

It's been a long time since I last etched a board. It's in the works, but here's what happens meanwhile. :)

Nice. Not as nice and cheap as the Parallella board, but at least you can already buy it.
