UNCLASSIFIED Hi Shep, Thanks for the info. I'm sure I will have plenty of questions once the FPGA cards arrive and we have the openCPI demos running. Is it going to be possible for us to get openCPI working with our various platforms/FMCs without a BlueSpec compiler? We've been quoted a high price, compared to the rest of the reference platform, for a not for profit BlueSpec licence. The cost of BlueSpec and it being sole source are probably our biggest concerns when considering if we should adopt OpenCPI as our middleware. The cost of a full BlueSpec license may also be a barrier for FPGA Card and FMC OEMs supporting openCPI by developing their own board support packages. Cheers, Troy

For example, our firm owns a 4DSP FMC150, but we have yet to port the existing opencpi device workers to the ML605. The ML605 is a fine, stable platform; and we have had few issues with it over the years. Specifically with regard to LVDS ADC/DAC integration remains porting the IOSERDES logic from V5 to V6. It may or may not be trivial. Examples from V5 are given here: https://github.com/opencpi/opencpi/blob/master/hdl/primitives/util_virte x5/imports/ddrInput2.v https://github.com/opencpi/opencpi/blob/master/hdl/primitives/util_virte x5/imports/ddrOutput2.v We can volley emails if you have more questions.

An initial review of your documents has shown that OpenCPI seems to meet our requirements for a middleware. The platforms we are targeting are your i7/ML605 reference platform for development and a uTCA platform for field trials. The field trial platform will consist of the follow or similar: - i7 quad core CPU, 8G RAM, PCIe Gen II x8 : http://www.gocct.com/sheets/AM/am31xx0x.htm - Xilinx V6 FPGA AMC, PCIe Gen II x8 : http://www.lyrtech.com/products/perseus_601x.php - One of these FMC o 8 x 250 Msam/sec ADC : http://www.4dsp.com/FMC108.php o 4/2/1 x 1.25/2.5/5 Gsam/sec ADC : http://www.4dsp.com/FMC125.php o 2 x 1 Gsam ADC, 2 x 1 Gsam DAC : http://www.4dsp.com/FMC110.php o RF Transceiver : http://www.lyrtech.com/products/radio420x.php Or preference for time synchronisation is Precision Time Protocol (IEEE 1588) for CPUs and 10MHz/PPS for FPGAs provided by the following or similar: - Meinberg LANTIME PTP - http://www.meinberg.de/english/products/lantime-m600-mrs-ptpv2.htm The use of PTP requires a recent version of the Linux kernel and we prefer a distribution which has all pre-requisites available as packages. Thus our preferred Linux distribution is Ubuntu 10.11. It appears that Ubuntu and PCIe Gen II x8 are not currently supported by OpenCPI. So some initial questions we have are: - When is the next stable release due? - How much of the specification documents will be implemented for the next release? - Are there any technical issues when selecting a platform that we need to be aware of? - How trivial is it to update OpenCPI to support the field trial platform? - Is there a roadmap available for platform support (OS, FPGA cards, FMC cards, Fabrics)? - The bug tracking tool at opencpi.org seems unused, is there an alternative being used? - The forum at opencpi.prg appears to be broken Any help will be much appreciated.
