| 14:32 | se6astian | hey guys!
|
| 14:32 | se6astian | just read your email
|
| 14:35 | TiN | hey! :)
|
| 14:37 | vila_ | hey, nice to meet you!
|
| 14:38 | TiN | me too, just read vila's email :)
|
| 14:39 | TiN | we are looking a camera similar to the new elphel
|
| 14:39 | vila_ | the thing is... we are working with cameras, and the problem we have with COTS cameras is that we are too far from the data
|
| 14:40 | vila_ | we need to run some real time calculations with the data stream
|
| 14:40 | se6astian | I assume you mean the upcoming Elphel 393, what is it that makes it only similar but not perfect for you?
|
| 14:40 | vila_ | and we've been looking quite a while for a camera that allow us to have some sillicon space near the sensor
|
| 14:42 | TiN | se6astian, mm no I mean the new camera, based on this post http://blog.elphel.com/2014/06/ddr3-memory-interface-on-xilinx-zynq-soc-free-software-compatible/
|
| 14:42 | TiN | is under development
|
| 14:42 | se6astian | yes thats Elphel 393
|
| 14:43 | vila_ | i like the elphel 393, but i thinks the best for me is to tell you what are we looking for. and you, the expert, tell me what do you think is a good option
|
| 14:43 | TiN | Ok, weird. I just thought that 393 has Spartan or something similar
|
| 14:43 | se6astian | Elphel 353 is the lastest camera model in production with spartan 6
|
| 14:44 | se6astian | but we (apertus) are not associated with Elphel in any way, I just know the guys from the past
|
| 14:45 | se6astian | so that "real time calculations" you mentioned you want to do inside the main FPGA or do you plan to use a dedicated chip ?
|
| 14:45 | vila_ | the main FPGA would be more than enough i think
|
| 14:46 | se6astian | great
|
| 14:46 | se6astian | we use a Zynq 7020 currently in the AXIOM Alpha and in the upcoming AXIOM Beta
|
| 14:46 | se6astian | this is the current image processing pipeline in the Alpha
|
| 14:46 | se6astian | https://wiki.apertus.org/index.php?title=AXIOM_Alpha_Software#Image_Pipeline
|
| 14:47 | se6astian | you can tap into the data and do you own stuff at any level as everything is released as open source
|
| 14:51 | vila_ | what are the chances of change the sensor at some point. (i.e. how sensor-specific is the rest of the camera)
|
| 14:52 | vila_ | it would be a major design change or just a little one?
|
| 14:52 | TiN | it looks really good, Zynq 7020 has dual cortex A9 :)
|
| 14:54 | vila_ | yeah!
|
| 14:55 | vila_ | we have now some designs based on a kintex-7 that would be the 7030, but is really close to it
|
| 14:55 | TiN | Uh, you are using the CMV12000 sensor. It has 64 LDVS lines@300MHz
|
| 14:56 | TiN | it is very similar to our current sensor too
|
| 14:58 | se6astian | we plan to use either Zynq 7015 or 7030 at a later point as we need the high speed transceivers
|
| 14:59 | se6astian | actually we plan to have several different sensor modules for the Beta
|
| 14:59 | se6astian | at least a Truesense Kac12040 and CMV12000 seem likely currently
|
| 15:00 | se6astian | changing sensor is intended so the design change is kept minimal but of course its still a bit of work
|
| 15:00 | vila_ | nice
|
| 15:01 | vila_ | and when do you think you'll have a release candidate of the Beta?
|
| 15:06 | se6astian | crowd funding should start soon and then approximately 6 months
|
| 15:10 | vila_ | how much do you expect to raise to fund the project?
|
| 15:10 | se6astian | we aim for around 100.000€
|
| 16:45 | Bertl | TiN: what is your current sensor?
|
| 16:48 | TiN | Bertl, vita 25k
|
| 16:48 | TiN | http://www.onsemi.com/pub/Collateral/NOIV1SN025KA-D.PDF
|
| 16:52 | Bertl | nice, is there anything you need an NDA for (datasheet wise)?
|
| 17:00 | se6astian | am I right with a per chip price estimate of around 4000$ ?
|
| 17:01 | Bertl | from the design, the vita25k would fit for the beta board
|
| 17:01 | Bertl | although it would be a little tricky to get it on-center
|
| 17:01 | Bertl | (because of the huge offset the visual area has)
|
| 17:02 | Bertl | TiN: do you use some kind of socket for the sensors?
|
| 17:03 | TiN | left the channel |
| 17:04 | TiN | joined the channel |
| 17:04 | TiN | Bertl, yes sadly is necessary an NDA to get "the full datasheet"
|
| 17:04 | Bertl | that would at least for us be a reason against the sensor
|
| 17:05 | TiN | yes we used a socket
|
| 17:06 | Bertl | what socket if you don't mind and where did you get it (and at what price)?
|
| 17:08 | Bertl | @NDA, although at first glance, the sensor datasheet you linked looks fairly complete
|
| 17:12 | TiN | Bertl, I really don't mind but the camera was made by a 3rd party provider and we don't have all the technical details. But I'll take a look on the board if I can see the model
|
| 17:13 | Bertl | ah, that's always nice, 3rd party development and not much data available :)
|
| 17:14 | TiN | yes so sad
|
| 17:19 | Bertl | so you want to go the FOSS/OH route next time because of the 3rd party experience? or is that unrelated?
|
| 17:29 | TiN | yes it is related, the experience wasn't good... But also we need to do some processing of the images in real time. Anyway that could be done in other ways, it is not really necessary all open...
|
| 17:31 | TiN | The most team uses free software, and we are trying to change to open hardware as well
