01:28 <Oksanaa> Hmm, this camera sensor technology sounds interesting: https://en.wikipedia.org/wiki/Foveon_X3_sensor

05:19 <Joerg-Neo900> Donnager: help

05:19 <Donnager> Joerg-Neo900: I am a ban management and anti-spam bot, using this plugin: <https://github.com/ncoevoet/ChanTracker>. If you need help, ask the user who invited me to your channel, or ask pinkieval.

08:43 <Joerg-Neo900> folks, while waiting for metacollin to show up again, let's do something useful and specify a few details for STEP2. To start with - which SoC to use?

08:48 <sn0wmonster> how about lowrisc (RISC-V)?

08:48 <sn0wmonster> is that gonna come out anytime soon?

08:48 <sn0wmonster> its something the Raspi guys founded (linux embedded chip)

08:49 <anon-> are you guys going to wait for him?

08:49 <sn0wmonster> their webite says it is expected to finish this year

08:49 <sn0wmonster> it would solve the whole TI chip issue at least

08:49 <sn0wmonster> (althoguh i have no clue how that would complicate the OS integration or anything else)

08:50 <sn0wmonster> the Linux kernel recently added RISC-V support iirc

08:50 <sn0wmonster> buti guess its a matter of the individual distros incorporating it?

08:50 <sn0wmonster> anon-, i don't think there's any point in waiting any longer

08:50 <Joerg-Neo900> that chip is planned to have a GPU? which one?

08:50 <sn0wmonster> but as there's no one else available, its kind of the default position :)

08:50 <sn0wmonster> Joerg-Neo900, let me dig it up

08:51 <sn0wmonster> http://www.lowrisc.org/

08:51 <sn0wmonster> i dont know if it has a GPU, where would i find that?

08:51 <sn0wmonster> How is this different to Raspberry Pi?

08:51 <sn0wmonster> not include a GPU.

08:51 <sn0wmonster> Our goals and focus are quite different. The Raspberry Pi exists to improve computer science education worldwide. A fully open-source SoC is not necessary to reach this goal, or even a pragmatic way of achieving it given the timescales involved. While it is an ultimate goal to support all the features of a modern commercial SoC, it will require a number of iterations of the design to achieve this. For example, early versions of our SoC will

08:52 <Joerg-Neo900> I'm very wary about using vaporware chips that have not even proven to work at all. Odds are the chip has SiErr bugs you can't work around, in first few releases

08:52 <sn0wmonster> so it doesn't have it early

08:52 <sn0wmonster> undoubtedly, yea

08:52 <sn0wmonster> http://www.lowrisc.org/faq/

08:54 <Joerg-Neo900> anon-: we got no other choice than waiting for him right now

08:56 <sn0wmonster> vaporware or not, it does seem to line up with our ethos

08:56 <sn0wmonster> perhaps worth investigating

08:56 <sn0wmonster> anyone here know anything about it?

08:56 <sn0wmonster> i emailed lowrisc with some questions, let me see what they say about the GPU and timelines

08:57 <Joerg-Neo900> RISC-V?

08:57 <sn0wmonster> yea

08:57 <Joerg-Neo900> timeline will be in the years, if they come up with something useful at all

08:58 <sn0wmonster> still want to look into it for future use

08:58 <sn0wmonster> better to keep track of these things than wait until everyone else is already using them :D

09:01 <Joerg-Neo900> of course :-) but consider how long it will take them to just _write_ something similar to full documentation of the chip. like https://community.nxp.com/servlet/JiveServlet/downloadBody/101840-102-5-17945/IMX6DQRMr2_part1.pdf https://community.nxp.com/servlet/JiveServlet/downloadBody/101783-102-6-17831/IMX6DQRMr2_part2.pdf, and writing that is a promille of the job, they also need to *design* and *implement* all that, and then debug it, and

09:01 <Joerg-Neo900> only THEN the chip could get benchmarked if it *really* performs in all relevant aspects

09:04 <Joerg-Neo900> then it might turn out the instruction set of the CPU or the system design (It's SYSTEM on a Chip, remember?) has a flaw in the concept that - while irrelevant for e.g. rPi - makes it not suited for battery powered embedded

09:04 <sn0wmonster> nice

09:04 <sn0wmonster> long haul then rey

09:04 <sn0wmonster> ey*

09:05 <sn0wmonster> Dec 2015: We have untethered the Rocket SoC, which now runs standalone on the KC705 and Nexys4DDR FPGAs. This release also includes support for simulation using Verilator and is accompanied by extensive documentation.

09:06 <sn0wmonster> seems like they are basing this new one off of something that was already around

09:10 <sn0wmonster> this is one of their workshop projects http://opencelerity.org/

23:34 <Oksanaa> sn0wmonster : FPGA doesn't sound particularly nice...
