| kristianpaul | wolfspraul: got your rca male-male cable, good ! | 12:12 |
|---|---|---|
| kristianpaul | lekernel: for the disable video-in is not just enought to comment define ENABLE_VIDEOIN at setup.v? | 12:13 |
| kristianpaul | ah well in boards/gen_capabilities.v i just see | 12:15 |
| kristianpaul | `ifdef ENABLE_VIDEOIN | 12:15 |
| kristianpaul | assign videoin = 1'b1; | 12:15 |
| kristianpaul | `else | 12:15 |
| kristianpaul | assign videoin = 1'b0; | 12:15 |
| kristianpaul | `endif | 12:15 |
| kristianpaul | hmm | 12:34 |
| kristianpaul | and a PULLDOWN | 13:14 |
| wolfspraul | pulldown? | 13:17 |
| kristianpaul | wolfspraul: http://www.xilinx.com/itp/xilinx4/data/docs/cgd/p13.html#1000057 | 13:20 |
| kristianpaul | hmm but reading more deeper i just may aply to 3-state nest.. | 13:21 |
| kristianpaul | nets* | 13:21 |
| kristianpaul | ah, wait may be pulldown as a library | 13:27 |
| kristianpaul | http://www.xilinx.com/support/documentation/sw_manuals/xilinx11/spartan6_hdl.pdf page 218 | 13:28 |
| kristianpaul | ergg, but we need ground it.. lets wait better a sebastien answer ;-) | 13:29 |
| lekernel | kristianpaul: we are talking about the video _out_ | 13:36 |
| kristianpaul | ahhh !! | 13:39 |
| kristianpaul | but reply somthing about modifying the verilog code.. | 13:40 |
| kristianpaul | okay this is physical not logical then, sorry for the confusion ! | 13:41 |
| lekernel | can't see what you mean. we want to set the voltage to 0 on all video out signals to the adc | 13:42 |
| lekernel | there are many ways to do that, but the simplest one is to assign 0 in the verilog source | 13:42 |
| kristianpaul | okay so input is not relevant, that was my confution | 13:47 |
| kristianpaul | nv my silly questions ;-) | 13:47 |
| rejon | milkymist fucking rules! | 15:57 |
| rejon | plugged into my parents flat screen totally cool ambient experience | 15:57 |
| Fallenou | :)) | 16:01 |
| lekernel | :) | 16:03 |
| lekernel | did you try with the video input too | 16:03 |
| lekernel | ? | 16:03 |
| rejon | lekernel not yet | 16:14 |
| rejon | what type of camera to use for that? | 16:14 |
| rejon | usb will work? | 16:15 |
| lekernel | no, composite | 16:15 |
| rejon | ok, i don't have a composite camera | 16:15 |
| rejon | need to pick one up | 16:15 |
| lekernel | look for cctv ones :) | 16:16 |
| lekernel | if you want cheap | 16:16 |
| rejon | i'll get one in china | 16:19 |
| rejon | next week | 16:19 |
| lekernel | phew. how many times are you on the plane a month? :) | 16:19 |
| Fallenou | in a little bit more than 2 hours we will know if Milkymist is accepted as a GSoC org :) | 16:25 |
| Fallenou | it seems they just made their first 28 nm fpga at Xilinx | 16:29 |
| Fallenou | they are testing it right now | 16:30 |
| Fallenou | http://www.youtube.com/watch?v=abmQPQ6Eiww | 16:30 |
| lekernel | I wonder where the timing models in ise 13.1 come from | 16:35 |
| lekernel | if they did not measure timing, how do they know about it? model a 28nm model? | 16:37 |
| Fallenou | ahah don't know | 16:37 |
| Fallenou | you mean they already had the timing information of the 7 series 28nm in ISE ? | 16:37 |
| lekernel | yes | 16:37 |
| Fallenou | before having made the chip ? | 16:37 |
| Fallenou | ahah nice | 16:37 |
| lekernel | maybe | 16:38 |
| lekernel | don't know | 16:38 |
| Fallenou | I am looking at the same exact video, but from altera side :p | 16:38 |
| Fallenou | it's like a youtube battle | 16:38 |
| lekernel | less than 300 views so far | 16:38 |
| lekernel | even milkymist videos are more popular | 16:38 |
| Fallenou | "look I'm at 10 Gb/s and the eye is wide open !!" | 16:38 |
| Fallenou | http://www.youtube.com/watch?v=EWnXBptAsW8&NR=1 | 16:38 |
| Fallenou | for altera 28nm chip | 16:39 |
| lekernel | btw: http://www.synopsys.com/Community/SNUG/UK/Pages/default.aspx | 16:39 |
| lekernel | http://www.synopsys.com/Community/SNUG/Pages/default.aspx | 16:39 |
| Fallenou | oh | 16:40 |
| lekernel | I most probably won't go, but it could be a nice place to learn about EDA/ASICs | 16:40 |
| lekernel | if you manage to get through the ivory tower's "authorized persons only" scanner | 16:41 |
| Fallenou | =) | 16:42 |
| Fallenou | http://www.synopsys.com/Community/SNUG/France/Pages/default.aspx | 16:43 |
| Fallenou | :) | 16:43 |
| lekernel | actually I emailed them about the registration details and fees, and the answer said "details are to be published later" (which they didn't) and that I had to note that such events were solely for "authorized persons" | 16:45 |
| lekernel | maybe just gatecrash | 16:45 |
| lekernel | sometimes it's surprisingly easy | 16:45 |
| Fallenou | to get access what do you basically need ? | 16:47 |
| Fallenou | to pay ? | 16:47 |
| Fallenou | to be from specific company? | 16:47 |
| lekernel | no idea :) | 16:48 |
| Fallenou | hum hum | 16:48 |
| Fallenou | it smells bad when nothing is explained :) | 16:49 |
| lekernel | pay synopsys licenses I guess | 16:49 |
| Fallenou | as if they wanted to advertise about it | 16:49 |
| Fallenou | but didn't want anyone to come | 16:49 |
| lekernel | that's how the asic business is | 16:49 |
| lekernel | very small world | 16:49 |
| Fallenou | or at least not someone not invited through some private channel | 16:49 |
| lekernel | very closed | 16:49 |
| lekernel | I'm not really surprised to see such behaviour | 16:50 |
| lekernel | and I wouldn't be surprised either if they had little security at the entrance | 16:50 |
| lekernel | even if there's a $3000 entrance fee | 16:50 |
| Fallenou | =) | 16:50 |
| Fallenou | anyway I won't be in London anymore in May | 16:51 |
| lekernel | usually this is paid for by rich companies who send their employees, and they don't really take into account curious individuals trying to get it | 16:51 |
| lekernel | interesting: http://www.freepatentsonline.com/6301693.pdf | 17:01 |
| lekernel | (asic placement algorithm) | 17:02 |
| Fallenou | But I guess you can't use it | 17:04 |
| Fallenou | right ? | 17:04 |
| scrts | if its patented, then.. :) | 17:06 |
| Fallenou | =( | 17:06 |
| larsc | well, of course you can use it. just pay the patent fee ;) | 17:06 |
| lekernel | software (i'd even say math) isn't patentable in europe | 17:08 |
| lekernel | if people want to argue about that or to find ways around the patent's claims, they feel free, but I won't spend a split second on that | 17:09 |
| lekernel | anyway, the first versions of my placer will use simulated annealing. that's for later. | 17:10 |
| Fallenou | lekernel: after llhdl and antares, I guess you will need a bitgen clone, is it difficult to do ? | 17:14 |
| lekernel | moderately | 17:15 |
| lekernel | it'll probably be built into the antares tools anyway... it's simpler than re-reading XDL files | 17:16 |
| lekernel | kristianpaul: looks interesting that labsurlab | 18:56 |
| kristianpaul | lekernel: yeah it is :-) | 18:56 |
| kristianpaul | lekernel: i'l aleready spare a talk with dorkbot people about milkymist too | 18:56 |
| kristianpaul | already* | 18:57 |
| lekernel | :) | 18:57 |
| lekernel | "uso y abuso de un satelite militar yankee" | 18:58 |
| lekernel | lol | 18:58 |
| kristianpaul | ;-)) | 18:58 |
| lekernel | at least you're doing it properly, I've heard (but I don't know if it's true) that some people simply hook a varactor doubler to a hamradio TX | 18:59 |
| lekernel | this sounds like a lot of EM pollution | 18:59 |
| lekernel | without proper filtering... | 19:00 |
| kristianpaul | (hook a varactor doubler to a hamradio TX) oh yes, its true ! | 19:00 |
| kristianpaul | There are lots of cases, one intentionals others not so, radio is really fun | 19:01 |
| lekernel | and what do you use for receiving? | 19:06 |
| lekernel | I mean, the "poor man's" solution like that one for TX :-) | 19:06 |
| kristianpaul | I dont know really, i just was told about what you pointed, but i bet another cheap radio and hackish atena will do the job. | 19:08 |
| kristianpaul | I can tell more about this after the labsurlab ;) | 19:08 |
| Fallenou | lekernel: seems we're not in gsoc this year again :x | 19:12 |
| kristianpaul | Why?? | 19:14 |
| rejon | suck! | 19:16 |
| rejon | i just saw | 19:16 |
| rejon | aiki got turned down too | 19:16 |
| rejon | man! | 19:16 |
| rejon | i tried harder than normal | 19:16 |
| rejon | they have a lots of legacy projects they support now | 19:16 |
| rejon | fine, well, at least google giving money | 19:16 |
| rejon | that was the last time i will try gsoc for any project | 19:16 |
| kristianpaul | (legacy projects they support now) | 19:17 |
| rejon | i would rather have $$$ anyway | 19:17 |
| Fallenou | enlightenment was refused too | 19:17 |
| kristianpaul | not sound well | 19:17 |
| kristianpaul | what? | 19:17 |
| Fallenou | dokuwiki got accepted ... | 19:17 |
| kristianpaul | :-( | 19:17 |
| Fallenou | wordpress too | 19:17 |
| rejon | yeah, well, they paid fabricatorz today though | 19:17 |
| rejon | which is good | 19:17 |
| rejon | :) | 19:17 |
| rejon | my company they paid 4 months late | 19:17 |
| lekernel | as usual I guess they gave you no reason for rejection? | 19:18 |
| rejon | lekernel right | 19:21 |
| rejon | actually its good | 19:21 |
| rejon | i just emailed the list | 19:21 |
| kristianpaul | 5000usd ! great :-) | 19:28 |
| Action: kristianpaul dint knew it about rejon company | 19:28 | |
| rejon | http://fabricatorz.com and aikilab | 19:28 |
| rejon | and of course sharism.cc | 19:28 |
| rejon | and sharism.org | 19:28 |
| kristianpaul | and you the sharism guy ! nice to met you some day :-) | 19:30 |
| rejon | sure | 19:31 |
| rejon | kristianpaul where you live? | 19:31 |
| kristianpaul | rejon: Buga, Colombia | 19:32 |
| kristianpaul | some far :-) | 19:32 |
| rejon | cool | 19:32 |
| kristianpaul | Fallenou: rtems got in gsoc? | 19:33 |
| Fallenou | yep | 19:34 |
| kristianpaul | kanzure_: hi, do you have something new to tell about organic semiconductors? :-) | 19:36 |
| Fallenou | oh I didn't know about this project | 22:21 |
| Fallenou | http://en.qi-hardware.com/wiki/Xu%C3%A9 | 22:21 |
| Fallenou | nice ! | 22:21 |
| kristianpaul | I wonder if i bought i dual/quad cored cheap cpu sintesis speed will improve a bit.. | 22:25 |
| kristianpaul | 45 minutes waiting to confirm a _single_ change is PAIN | 22:26 |
| Fallenou | yes it is :( | 22:26 |
| kristianpaul | I bet that what more encorage sebastien for start llhdl ;-) | 22:26 |
| Fallenou | AFAIK the synthesis process is purely mono threaded | 22:26 |
| kristianpaul | argh! | 22:26 |
| Fallenou | so you would not gain anything with N cores | 22:26 |
| Fallenou | Xst and all the toolchain uses only one core :( | 22:27 |
| kristianpaul | -_- | 22:27 |
| Fallenou | but the more you add cores the more you can do things in parallel without slowing down the synthesis :) | 22:27 |
| kristianpaul | hahag | 22:27 |
| kristianpaul | s/g/h | 22:27 |
| kristianpaul | nah | 22:27 |
| kristianpaul | i may add ram later for some experiments | 22:27 |
| kristianpaul | i'm happy with my single core | 22:28 |
| Fallenou | it could be great to have several server to do synthesis on them | 22:28 |
| Fallenou | you could test several changes at the same time | 22:28 |
| Fallenou | if you have like a 8 cores machine | 22:28 |
| Fallenou | you can put 8 virtual machines | 22:28 |
| kristianpaul | ah, servers.. | 22:28 |
| Fallenou | and do 8 synthesis in parallel | 22:28 |
| kristianpaul | wpwrak: tuxrandon have some GUI isnt? and VNC? i remenber | 22:29 |
| Fallenou | or just with some cp trick and without any virtualmachine :p | 22:29 |
| kristianpaul | no man two sintesis threas and my computer will burnout.. | 22:30 |
| Fallenou | yes I meant on a server | 22:31 |
| Fallenou | with several cores :) | 22:31 |
| kristianpaul | :-) | 22:31 |
| Fallenou | and proper fans / heat sinks | 22:31 |
| Fallenou | it still won't improve the synthesis time | 22:32 |
| Fallenou | but can make it possible to test several changes in less time | 22:32 |
| wpwrak | kristianpaul: tuxrandon ? qu'est-ce que c'est ? | 22:32 |
| Fallenou | wpwrak: il ne parle pas francais je pense | 22:32 |
| wpwrak | Fallenou: i think it's the universal symbol of puzzledness ;-) | 22:33 |
| kristianpaul | wpwrak: je ne parle francais | 22:33 |
| Fallenou | wpwrak: just say "wtfff ?" | 22:33 |
| Fallenou | it's more universal :p | 22:33 |
| kristianpaul | wpwrak: turandot, sorry typo | 22:33 |
| kristianpaul | ah no | 22:34 |
| kristianpaul | no | 22:34 |
| Last message repeated 1 time(s). | 22:34 | |
| kristianpaul | wpwrak: fidelio ! | 22:34 |
| wpwrak | Fallenou: also very good to convey early to students the complexity they'll face in the coming years :) | 22:34 |
| Fallenou | the complexity of what ? | 22:35 |
| kristianpaul | life? | 22:35 |
| kristianpaul | physics? | 22:35 |
| kristianpaul | :p | 22:35 |
| kristianpaul | s/software/gas | 22:35 |
| wpwrak | turandot sounds dangerous. "While working on Turandot, Puccini grew ill and died [...]" | 22:35 |
| kristianpaul | hahaha | 22:35 |
| wpwrak | Fallenou: the french language | 22:35 |
| kristianpaul | wpwrak: (french) but you speak spanish, the swich is not so _big_ | 22:36 |
| Fallenou | I don't get it , is kristianpaul coming to study in france ? | 22:36 |
| kristianpaul | lol | 22:36 |
| kristianpaul | Not that i'm aware off ;-) | 22:36 |
| Fallenou | ok :p | 22:36 |
| Fallenou | kristianpaul: a few minutes ago 4 spanish-or-assimilated guys just started following me on twitter | 22:37 |
| Fallenou | I guess it comes from you :p | 22:37 |
| kristianpaul | oh yes? | 22:37 |
| wpwrak | Fallenou: naw, don't you know the old song "psycho killer" (or the parody "psycho chicken") ? there, they also use "qu'est-ce que c'est" as a term of puzzlement in an otherwise english text | 22:37 |
| Fallenou | like "truequedigital" or "cartograsonoras" | 22:37 |
| kristianpaul | i dont know use twitter, just mirror microblof from identi.ca | 22:38 |
| Fallenou | oh no sorry wpwrak :) didn't know ! | 22:38 |
| Fallenou | ok :p | 22:38 |
| kristianpaul | let me confirm thats not spam | 22:38 |
| wpwrak | Fallenou: http://en.wikipedia.org/wiki/Psycho_Killer | 22:38 |
| Fallenou | there is miqrorelatos too | 22:39 |
| Fallenou | and camkiant | 22:39 |
| Fallenou | camikant | 22:39 |
| Fallenou | wpwrak: thanks :) | 22:39 |
| kristianpaul | ah yes, trusty near related people | 22:40 |
| kristianpaul | may be from labsurlab i think | 22:40 |
| kristianpaul | yes | 22:41 |
| Fallenou | it's right after i retweeted something from you | 22:41 |
| Fallenou | about your labsurlab stuff in fact :) | 22:42 |
| Fallenou | kristianpaul: is there going to be a milkymist show/presentation somewhere ? | 22:42 |
| kristianpaul | phew, almost finishing a better diagram for milkymist SoC, now do it in dia :p | 22:43 |
| Fallenou | at labsurlab ? | 22:43 |
| Fallenou | oh a new soc block diagram ? :) cool ! | 22:43 |
| kristianpaul | (at labsurlab) not yet, it begin at april 4 | 22:50 |
| kristianpaul | conbus 2x5: mico32 <-> slaves (NOR, ROM, CSR, FML) | 23:28 |
| kristianpaul | and i gues in the that order arbitrer take cares.. | 23:30 |
| scrts | hm | 23:30 |
| kristianpaul | (NOR, ROM, YSB, CSR, FML)** | 23:30 |
| kristianpaul | s/YSB/USB | 23:31 |
| scrts | are there any plans of streaming video through lan? :) | 23:31 |
| kristianpaul | scrts: i think that pushing data to lan is the only think ethernet drivr do best | 23:31 |
| kristianpaul | (note not makinf resposible Fallenou for this) | 23:31 |
| CIA-37 | antares: Sebastien Bourdeauducq master * rb27b033 / (3 files): place: enumerate control sets - http://bit.ly/i6Nq9u | 23:31 |
| CIA-37 | antares: Sebastien Bourdeauducq master * rb5f3c14 / (5 files in 3 dirs): pack: new architecture (incomplete) - http://bit.ly/goqqIl | 23:31 |
| scrts | well, its not so easy to push video data stream, since it can't be interrupted :) | 23:32 |
| kristianpaul | scrts: so yes, why not, but can you figure out how to dump video-in to a know format? thats the missing part i bet | 23:32 |
| scrts | I have a task to do TS to IP | 23:33 |
| scrts | however that will be on NIOS :\ | 23:33 |
| kristianpaul | hmm | 23:33 |
| scrts | TS -> transport stream | 23:33 |
| scrts | I think it will be MPEG-2 encoded | 23:33 |
| kristianpaul | so conbus 2x5: mico32 <-> slaves (NOR, ROM, USB, CSR, FML) that order arbitrer take cares i guess | 23:33 |
| kristianpaul | and slaves, 5 to date are maped in memory at thar order | 23:33 |
| Fallenou | kristianpaul: you mean "no pushing data to lan" is what the driver does best ? :p | 23:36 |
| Fallenou | second thing being crashing | 23:37 |
| kristianpaul | Fallenou: push to lan | 23:38 |
| kristianpaul | not lan to mm1 | 23:38 |
| kristianpaul | i remner i get a 4x troughtput and not crash when pulling a fake file from the mm1 using ftp | 23:39 |
| Fallenou | so you mean one way works better than the other ? | 23:40 |
| kristianpaul | oh, yes i do | 23:41 |
| kristianpaul | so lets say stream is much more posible ;-) | 23:41 |
| Fallenou | oh ok so uploading from M1 works better than downloading | 23:42 |
| Fallenou | well the new driver design should have improved the downloading part on M1 side :( | 23:42 |
| Fallenou | too bad it didn't work | 23:42 |
| kristianpaul | so conbus 6x1: (mico32, AC97, PFPU, TMU*, Minimac ) <-> slave FML so this the DMA-like thing | 23:45 |
| kristianpaul | as FML is the proper way in order to get to ram i guess | 23:45 |
| Fallenou | yes | 23:46 |
| kristianpaul | but note the TMU* is part also of the FML bus not just wishbone | 23:46 |
| Fallenou | FML is Fast memory link | 23:46 |
| Fallenou | it's aimed at accessing ram at high speed | 23:46 |
| Fallenou | good for dma | 23:46 |
| kristianpaul | i like High Trughput Link ;-) | 23:46 |
| kristianpaul | Trought* | 23:46 |
| kristianpaul | me so lazy, i took two weeks to understand this :( | 23:47 |
| Fallenou | it's not easy to understand all these things, if it's not your field of study | 23:48 |
| Fallenou | and if you do not have all the day to study it :) | 23:48 |
| kristianpaul | all day, oh my shame.. | 23:48 |
| Fallenou | you're working right ? | 23:49 |
| kristianpaul | yeap | 23:49 |
| Fallenou | so you just have a look at milkymist during your free time | 23:49 |
| Fallenou | it's usually a small amount of time :) | 23:49 |
| Fallenou | not easy to progress | 23:49 |
| kristianpaul | yeah, and meanwhile travel | 23:49 |
| kristianpaul | but i'll get there :-) | 23:49 |
| Fallenou | sure ! | 23:49 |
| kristianpaul | (field of study) i never took microprocesor subject at univesity, so yes i also had to read about it | 23:50 |
| Fallenou | I mean you didn't study "soc design" as your main subject | 23:51 |
| kristianpaul | nah | 23:51 |
| Fallenou | neither do I | 23:51 |
| Fallenou | my subject is not even electronic nor fpga at all | 23:51 |
| Fallenou | it's more network and telecom | 23:51 |
| kristianpaul | oh, i work on network security ! | 23:52 |
| Fallenou | nice :) | 23:52 |
| kristianpaul | well more log analisys part but also network too | 23:52 |
| Fallenou | oh | 23:52 |
| Fallenou | I met a guy yesterday who did log analysis for network too | 23:52 |
| Fallenou | at getitmade meeting :p | 23:52 |
| kristianpaul | :_) | 23:53 |
| Action: Fallenou is really chatty | 23:54 | |
| Action: Fallenou speaks too much | 23:54 | |
