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 implementation
I believe this is the largest buffer size of any of the "SUMP" implementations. It runs great with the latest JaWi OLS Java client.
The implementation uses about 22% of the slices and 96 block rams (out of 116 total).
BTW, removing the advanced triggers reduce the size to about 7% of the slices making it quite possible to have this as an internal logic analyzer in a FPGA project.
More info and links to the complete XISE project and the bit file can be found at the saanlima forums (sight, the link got blocked, I guess you just have to google "pipistrello fpga").
