mkarlsson ported the Open Bench Logic Sniffer code to run on Pipistrello LX45:
FYI, I have ported the Demon 3.07 code to Pipistrello LX45 FPGA board with the following changes:
1) The sample buffer size is increased by a factor of 8 from 24kB to 192kB
2) The interface is changed to serial (Pipistrello uses a FTDI 2232H High-speed USB chip)
3) The baud rate is increased from 115200 to 921600 to reduce the data upload time
4) The meta data has changed to indicated Pipistello implementationI believe this is the largest buffer size of any of the “SUMP” implementations. It runs great with the latest JaWi OLS Java client.
Get a Logic Sniffer for $50, with free worldwide shipping.
Hmm…200MHz sampling.
A Pipistrello LX45 is $150: http://saanlima.com/store/index.php?route=product/product&product_id=51
Still need probes (not sure where to get them) for a logic analyzer…
These should do:

and maybe an bufferwing http://www.seeedstudio.com/depot/logic-sniffer-16bit-input-buffer-wing-p-721.html
When I get my parallella board, I’ll probably port the core to it.
The 2 boards I ordered in the kickstarter campaign are Z-7020 based and will have lots of room. With the embedded ARM cores, you can even build a portable LA with no PC at all.
The boards you can order now are $99 , like the Kickstarter price, but will come with a Zynq 7010, not the 7020.
The parallella has 1GB or 32-bit wide DDR3L currently running at 400MHz, which should be enough for 64 bits @200MHz with lots of room to spare (e.g. with spares enough for the CPU and refresh access).
