my first microZed board

Just got this from production:

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, --sp

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. -- John Larkin Highland Technology, Inc jlarkin att highlandtechnology dott com http://www.highlandtechnology.com

It's not nice, it's beautiful.

No, just three rotary hex switches that set the IP address. The customer insisted on that. https://dl.dropboxusercontent.com/u/53724080/PCBs/ASP_SN1_side.jpg 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! -- John Larkin Highland Technology, Inc jlarkin att highlandtechnology dott com http://www.highlandtechnology.com

Well rapsi has that, but only one core.

http://www.bugblat.com/products/pif/ So all together with tools about 75 $; raspi + FPGA board. 2 rapsis ... makes... 3 rapsis makes... 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...

If my understanding is correct, the RPi's GPIO is particularly weedy and slow. OTOH, the Zync has a high performance FPGA tightly integrated with the CPU and memory. Hence if FPGA-CPU-DRAM communication performance is important, the Zync would win hands down.

Which version of the Xilix toolset are you using? Please let us know if you continue to find things easy, or if you have had to workaround infelicities.
